Mtools 4.0.10

This is mtools' documentation.

Introduction

Mtools is a collection of tools to allow Unix systems to manipulate MS-DOS files: read, write, and move around files on an MS-DOS filesystem (typically a floppy disk). Where reasonable, each program attempts to emulate the MS-DOS equivalent command. However, unnecessary restrictions and oddities of DOS are not emulated. For instance, it is possible to move subdirectories from one subdirectory to another.

Mtools is sufficient to give access to MS-DOS filesystems. For instance, commands such as mdir a: work on the a: floppy without any preliminary mounting or initialization (assuming the default `/etc/mtools.conf' works on your machine). With mtools, one can change floppies too without unmounting and mounting.

1. Where to get mtools

Mtools can be found at the following places (and their mirrors):
 
http://ftp.gnu.org/gnu/mtools/mtools-4.0.10.tar.gz
http://mtools.linux.lu/mtools-4.0.10.tar.gz
ftp://www.tux.org/pub/knaff/mtools/mtools-4.0.10.tar.gz
ftp://ibiblio.unc.edu/pub/Linux/utils/disk-management/mtools-4.0.10.tar.gz

Before reporting a bug, make sure that it has not yet been fixed in the Alpha patches which can be found at:
 
http://ftp.gnu.org/gnu/mtools/
http://mtools.linux.lu/
ftp://www.tux.org/pub/knaff/mtools

These patches are named mtools-version-ddmm.taz, where version stands for the base version, dd for the day and mm for the month. Due to a lack of space, I usually leave only the most recent patch.

There is an mtools mailing list at mtools @ tux.org . Please send all bug reports to this list. You may subscribe to the list by sending a message with 'subscribe mtools @ tux.org' in its body to majordomo @ tux.org . (N.B. Please remove the spaces around the "@" both times. I left them there in order to fool spambots.) Announcements of new mtools versions will also be sent to the list, in addition to the linux announce newsgroups. The mailing list is archived at http://lists.gnu.org/pipermail/info-mtools/

2.1 Options and filenames

MS-DOS filenames are composed of a drive letter followed by a colon, a subdirectory, and a filename. Only the filename part is mandatory, the drive letter and the subdirectory are optional. Filenames without a drive letter refer to Unix files. Subdirectory names can use either the '/' or '\' separator. The use of the '\' separator or wildcards requires the names to be enclosed in quotes to protect them from the shell. However, wildcards in Unix filenames should not be enclosed in quotes, because here we want the shell to expand them.

The regular expression "pattern matching" routines follow the Unix-style rules. For example, `*' matches all MS-DOS files in lieu of `*.*'. The archive, hidden, read-only and system attribute bits are ignored during pattern matching.

All options use the - (minus) as their first character, not / as you'd expect in MS-DOS.

Most mtools commands allow multiple filename parameters, which doesn't follow MS-DOS conventions, but which is more user-friendly.

Most mtools commands allow options that instruct them how to handle file name clashes. See section 2.5 Name clashes, for more details on these. All commands accept the -V flags which prints the version, and most accept the -v flag, which switches on verbose mode. In verbose mode, these commands print out the name of the MS-DOS files upon which they act, unless stated otherwise. See section 4. Command list, for a description of the options which are specific to each command.

2.2 Drive letters

The meaning of the drive letters depends on the target architectures. However, on most target architectures, drive A is the first floppy drive, drive B is the second floppy drive (if available), drive J is a Jaz drive (if available), and drive Z is a Zip drive (if available). On those systems where the device name is derived from the SCSI id, the Jaz drive is assumed to be at Scsi target 4, and the Zip at Scsi target 5 (factory default settings). On Linux, both drives are assumed to be the second drive on the Scsi bus (/dev/sdb). The default settings can be changes using a configuration file (see section 3. How to configure mtools for your environment).

The drive letter : (colon) has a special meaning. It is used to access image files which are directly specified on the command line using the -i options.

Example:
 
 mcopy -i my-image-file.bin ::file1 ::file2 .

This copies file1 and file2 from the image file (my-image-file.bin) to the /tmp directory.

You can also supply an offset within the image file by including @@offset into the file name.

Example:
 
 mcopy -i my-image-file.bin@@1M ::file1 ::file2 .

This looks for the image at the offset of 1M in the file, rather than at its beginning.

2.3 Current working directory

The mcd command (4.6 Mcd) is used to establish the device and the current working directory (relative to the MS-DOS filesystem), otherwise the default is assumed to be A:/. However, unlike MS-DOS, there is only one working directory for all drives, and not one per drive.

2.4 VFAT-style long file names

This version of mtools supports VFAT style long filenames. If a Unix filename is too long to fit in a short DOS name, it is stored as a VFAT long name, and a companion short name is generated. This short name is what you see when you examine the disk with a pre-7.0 version of DOS. The following table shows some examples of short names:

 
Long name       MS-DOS name     Reason for the change
---------       ----------      ---------------------
thisisatest     THISIS~1        filename too long
alain.knaff     ALAIN~1.KNA     extension too long
prn.txt         PRN~1.TXT       PRN is a device name
.abc            ABC~1           null filename
hot+cold        HOT_CO~1        illegal character

As you see, the following transformations happen to derive a short name:

The initial Unix-style file name (whether long or short) is also called the primary name, and the derived short name is also called the secondary name.

Example:
 
 mcopy /etc/motd a:Reallylongname
Mtools creates a VFAT entry for Reallylongname, and uses REALLYLO as a short name. Reallylongname is the primary name, and REALLYLO is the secondary name.
 
 mcopy /etc/motd a:motd
Motd fits into the DOS filename limits. Mtools doesn't need to derivate another name. Motd is the primary name, and there is no secondary name.

In a nutshell: The primary name is the long name, if one exists, or the short name if there is no long name.

Although VFAT is much more flexible than FAT, there are still names that are not acceptable, even in VFAT. There are still some illegal characters left (\"*\\<>/?:|), and device names are still reserved.

 
Unix name       Long name       Reason for the change
---------       ----------      ---------------------
prn             prn-1           PRN is a device name
ab:c            ab_c-1          illegal character

As you see, the following transformations happen if a long name is illegal:

2.5 Name clashes

When writing a file to disk, its long name or short name may collide with an already existing file or directory. This may happen for all commands which create new directory entries, such as mcopy, mmd, mren, mmove. When a name clash happens, mtools asks you what it should do. It offers several choices:

overwrite
Overwrites the existing file. It is not possible to overwrite a directory with a file.
rename
Renames the newly created file. Mtools prompts for the new filename
autorename
Renames the newly created file. Mtools chooses a name by itself, without prompting
skip
Gives up on this file, and moves on to the next (if any)

To chose one of these actions, type its first letter at the prompt. If you use a lower case letter, the action only applies for this file only, if you use an upper case letter, the action applies to all files, and you won't be prompted again.

You may also chose actions (for all files) on the command line, when invoking mtools:

-D o
Overwrites primary names by default.
-D O
Overwrites secondary names by default.
-D r
Renames primary name by default.
-D R
Renames secondary name by default.
-D a
Autorenames primary name by default.
-D A
Autorenames secondary name by default.
-D s
Skip primary name by default.
-D S
Skip secondary name by default.
-D m
Ask user what to do with primary name.
-D M
Ask user what to do with secondary name.

Note that for command line switches lower/upper differentiates between primary/secondary name whereas for interactive choices, lower/upper differentiates between just-this-time/always.

The primary name is the name as displayed in Windows 95 or Windows NT: i.e. the long name if it exists, and the short name otherwise. The secondary name is the "hidden" name, i.e. the short name if a long name exists.

By default, the user is prompted if the primary name clashes, and the secondary name is autorenamed.

If a name clash occurs in a Unix directory, mtools only asks whether to overwrite the file, or to skip it.

2.6 Case sensitivity of the VFAT filesystem

The VFAT filesystem is able to remember the case of the filenames. However, filenames which differ only in case are not allowed to coexist in the same directory. For example if you store a file called LongFileName on a VFAT filesystem, mdir shows this file as LongFileName, and not as Longfilename. However, if you then try to add LongFilename to the same directory, it is refused, because case is ignored for clash checks.

The VFAT filesystem allows to store the case of a filename in the attribute byte, if all letters of the filename are the same case, and if all letters of the extension are the same case too. Mtools uses this information when displaying the files, and also to generate the Unix filename when mcopying to a Unix directory. This may have unexpected results when applied to files written using an pre-7.0 version of DOS: Indeed, the old style filenames map to all upper case. This is different from the behavior of the old version of mtools which used to generate lower case Unix filenames.

2.7 high capacity formats

Mtools supports a number of formats which allow to store more data on disk as usual. Due to different operating system abilities, these formats are not supported on all OS'es. Mtools recognizes these formats transparently where supported.

In order to format these disks, you need to use an operating system specific tool. For Linux, suitable floppy tools can be found in the fdutils package at the following locations~:
 
ftp://www.tux.org/pub/knaff/fdutils/.
ftp://ibiblio.unc.edu/pub/Linux/utils/disk-management/fdutils-*

See the manpages included in that package for further detail: Use superformat to format all formats except XDF, and use xdfcopy to format XDF.

2.7.1 More sectors  Putting more sectors per track on the disk
2.7.2 Bigger sectors  Use bigger sectors to save header space
2.7.3 2m  Use a standard first track
2.7.4 XDF  OS/2's eXtended density format


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

2.7.1 More sectors

The oldest method of fitting more data on a disk is to use more sectors and more cylinders. Although the standard format uses 80 cylinders and 18 sectors (on a 3 1/2 high density disk), it is possible to use up to 83 cylinders (on most drives) and up to 21 sectors. This method allows to store up to 1743K on a 3 1/2 HD disk. However, 21 sector disks are twice as slow as the standard 18 sector disks because the sectors are packed so close together that we need to interleave them. This problem doesn't exist for 20 sector formats.

These formats are supported by numerous DOS shareware utilities such as fdformat and vgacopy. In his infinite hybris, Bill Gate$ believed that he invented this, and called it `DMF disks', or `Windows formatted disks'. But in reality, it has already existed years before! Mtools supports these formats on Linux, on SunOs and on the DELL Unix PC.


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

2.7.2 Bigger sectors

By using bigger sectors it is possible to go beyond the capacity which can be obtained by the standard 512-byte sectors. This is because of the sector header. The sector header has the same size, regardless of how many data bytes are in the sector. Thus, we save some space by using fewer, but bigger sectors. For example, 1 sector of 4K only takes up header space once, whereas 8 sectors of 512 bytes have also 8 headers, for the same amount of useful data.

This method allows to store up to 1992K on a 3 1/2 HD disk.

Mtools supports these formats only on Linux.

2.7.3 2m

The 2m format was originally invented by Ciriaco Garcia de Celis. It also uses bigger sectors than usual in order to fit more data on the disk. However, it uses the standard format (18 sectors of 512 bytes each) on the first cylinder, in order to make these disks easyer to handle by DOS. Indeed this method allows to have a standard sized bootsector, which contains a description of how the rest of the disk should be read.

However, the drawback of this is that the first cylinder can hold less data than the others. Unfortunately, DOS can only handle disks where each track contains the same amount of data. Thus 2m hides the fact that the first track contains less data by using a shadow FAT. (Usually, DOS stores the FAT in two identical copies, for additional safety. XDF stores only one copy, and it tells DOS that it stores two. Thus the same that would be taken up by the second FAT copy is saved.) This also means that your should never use a 2m disk to store anything else than a DOS fs.

Mtools supports these format only on Linux.


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

2.7.4 XDF

XDF is a high capacity format used by OS/2. It can hold 1840 K per disk. That's lower than the best 2m formats, but its main advantage is that it is fast: 600 milliseconds per track. That's faster than the 21 sector format, and almost as fast as the standard 18 sector format. In order to access these disks, make sure mtools has been compiled with XDF support, and set the use_xdf variable for the drive in the configuration file. See section 5. Architecture specific compilation flags, and 3.5.5 General Purpose Drive Variables, for details on how to do this. Fast XDF access is only available for Linux kernels which are more recent than 1.1.34.

Mtools supports this format only on Linux.

Caution / Attention distributors: If mtools is compiled on a Linux kernel more recent than 1.3.34, it won't run on an older kernel. However, if it has been compiled on an older kernel, it still runs on a newer kernel, except that XDF access is slower. It is recommended that distribution authors only include mtools binaries compiled on kernels older than 1.3.34 until 2.0 comes out. When 2.0 will be out, mtools binaries compiled on newer kernels may (and should) be distributed. Mtools binaries compiled on kernels older than 1.3.34 won't run on any 2.1 kernel or later.

2.8 Exit codes

All the Mtools commands return 0 on success, 1 on utter failure, or 2 on partial failure. All the Mtools commands perform a few sanity checks before going ahead, to make sure that the disk is indeed an MS-DOS disk (as opposed to, say an ext2 or minix disk). These checks may reject partially corrupted disks, which might otherwise still be readable. To avoid these checks, set the MTOOLS_SKIP_CHECK environmental variable or the corresponding configuration file variable (see section 3.4 Global variables)
[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

2.9 Bugs

An unfortunate side effect of not guessing the proper device (when multiple disk capacities are supported) is an occasional error message from the device driver. These can be safely ignored.

The fat checking code chokes on 1.72 Mb disks mformatted with pre-2.0.7 mtools. Set the environmental variable MTOOLS_FAT_COMPATIBILITY (or the corresponding configuration file variable, 3.4 Global variables) to bypass the fat checking.

3. How to configure mtools for your environment


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

3.1 Description

This sections explains the syntax of the configurations files for mtools. The configuration files are called `/usr/local/etc/mtools.conf' and `~/.mtoolsrc'. If the environmental variable MTOOLSRC is set, its contents is used as the filename for a third configuration file. These configuration files describe the following items:

3.2 Location of the configuration files  Where mtools looks for its configuration files
3.2.1 General configuration file syntax  The layout of the configuration files
3.3 Default values  Why you don't need a config file in most cases
3.4 Global variables  Variables that are independent of the drive
3.5 Per drive flags and variables  Variables that are specific to a given drive
3.6 Location of configuration files and parsing order  
3.7 Backwards compatibility with old configuration file syntax  Backwards compatibility


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

3.2 Location of the configuration files

`/usr/local/etc/mtools.conf' is the system-wide configuration file, and `~/.mtoolsrc' is the user's private configuration file.

On some systems, the system-wide configuration file is called `/etc/default/mtools.conf' instead.


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

3.2.1 General configuration file syntax

The configuration files is made up of sections. Each section starts with a keyword identifying the section followed by a colon. Then follow variable assignments and flags. Variable assignments take the following form:
 
name=value
Flags are lone keywords without an equal sign and value following them. A section either ends at the end of the file or where the next section begins.

Lines starting with a hash (#) are comments. Newline characters are equivalent to whitespace (except where ending a comment). The configuration file is case insensitive, except for item enclosed in quotes (such as filenames).


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

3.3 Default values

For most platforms, mtools contains reasonable compiled-in defaults for physical floppy drives. Thus, you usually don't need to bother with the configuration file, if all you want to do with mtools is to access your floppy drives. On the other hand, the configuration file is needed if you also want to use mtools to access your hard disk partitions and dosemu image files.


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

3.4 Global variables

Global flags may be set to 1 or to 0.

The following global flags are recognized:

MTOOLS_SKIP_CHECK
If this is set to 1, mtools skips most of its sanity checks. This is needed to read some Atari disks which have been made with the earlier ROMs, and which would not be recognized otherwise.
MTOOLS_FAT_COMPATIBILITY
If this is set to 1, mtools skips the fat size checks. Some disks have a bigger FAT than they really need to. These are rejected if this option is not set.
MTOOLS_LOWER_CASE
If this is set to 1, mtools displays all-upper-case short filenames as lowercase. This has been done to allow a behavior which is consistent with older versions of mtools which didn't know about the case bits.
MTOOLS_NO_VFAT
If this is set to 1, mtools won't generate VFAT entries for filenames which are mixed-case, but otherwise legal dos filenames. This is useful when working with DOS versions which can't grok VFAT longnames, such as FreeDos.
MTOOLS_DOTTED_DIR
In a wide directory, prints the short name with a dot instead of spaces separating the basename and the extension.
MTOOLS_NAME_NUMERIC_TAIL
If this is set to one (default), generate numeric tails for all long names (~1). If set to zero, only generate numeric tails if otherwise a clash would have happened.
MTOOLS_TWENTY_FOUR_HOUR_CLOCK
If 1, uses the European notation for times (twenty four hour clock), else uses the UK/US notation (am/pm)

Example: Inserting the following line into your configuration file instructs mtools to skip the sanity checks:
 
  MTOOLS_SKIP_CHECK=1

Global variables may also be set via the environment:
 
  export MTOOLS_SKIP_CHECK=1

Global string variables may be set to any value:

MTOOLS_DATE_STRING
The format used for printing dates of files. By default, is dd-mm-yyyy.

[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

3.5.1 General information

Per drive flags and values may be described in a drive section. A drive section starts with drive "driveletter" :

Then follow variable-value pairs and flags.

This is a sample drive description:
 
  drive a:
    file="/dev/fd0" use_xdf=1


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

3.5.2 Location information

For each drive, you need to describe where its data is physically stored (imag file, physical device, partition, offset).

file
The name of the file or device holding the disk image. This is mandatory. The file name should be enclosed in quotes.

partition
Tells mtools to treat the drive as a partitioned device, and to use the given partition. Only primary partitions are accessible using this method, and they are numbered from 1 to 4. For logical partitions, use the more general offset variable. The partition variable is intended for removable media such as Syquests, ZIP drives, and magneto-optical disks. Although traditional DOS sees Syquests and magneto-optical disks as `giant floppy disks' which are unpartitioned, OS/2 and Windows NT treat them like hard disks, i.e. partioned devices. The partition flag is also useful DOSEMU hdimages. It is not recommended for hard disks for which direct access to partitions is available through mounting.

offset
Describes where in the file the MS-DOS filesystem starts. This is useful for logical partitions in DOSEMU hdimages, and for ATARI ram disks. By default, this is zero, meaning that the filesystem starts right at the beginning of the device or file.

3.5.3 Disk Geometry Configuration

Geometry information describes the physical characteristics about the disk. Its has three purposes:

formatting
The geometry information is written into the boot sector of the newly made disk. However, you may also describe the geometry information on the command line. See section 4.13 Mformat, for details.
filtering
On some Unices there are device nodes which only support one physical geometry. For instance, you might need a different node to access a disk as high density or as low density. The geometry is compared to the actual geometry stored on the boot sector to make sure that this device node is able to correctly read the disk. If the geometry doesn't match, this drive entry fails, and the next drive entry bearing the same drive letter is tried. See section 3.5.7 Supplying multiple descriptions for a drive, for more details on supplying several descriptions for one drive letter.

If no geometry information is supplied in the configuration file, all disks are accepted. On Linux (and on Sparc) there exist device nodes with configurable geometry (`/dev/fd0', `/dev/fd1' etc), and thus filtering is not needed (and ignored) for disk drives. (Mtools still does do filtering on plain files (disk images) in Linux: this is mainly intended for test purposes, as I don't have access to a Unix which would actually need filtering).

If you do not need filtering, but want still a default geometry for mformatting, you may switch off filtering using the mformat_only flag.

If you want filtering, you should supply the filter flag. If you supply a geometry, you must supply one of both flags.

initial geometry
On devices that support it (usually floppy devices), the geometry information is also used to set the initial geometry. This initial geometry is applied while reading the boot sector, which contains the real geometry. If no geometry information is supplied in the configuration file, or if the mformat_only flag is supplied, no initial configuration is done.

On Linux, initial geometry is not really needed, as the configurable devices are able to auto-detect the disk type accurately enough (for most common formats) to read the boot sector.

Wrong geometry information may lead to very bizarre errors. That's why I strongly recommend that you add the mformat_only flag to your drive description, unless you really need filtering or initial geometry.

The following geometry related variables are available:

cylinders
tracks
The number of cylinders. (cylinders is the preferred form, tracks is considered obsolete)
heads
The number of heads (sides).
sectors
The number of sectors per track.

Example: the following drive section describes a 1.44M drive:

 
  drive a:
      file="/dev/fd0H1440"
      fat_bits=12
      cylinders=80 heads=2 sectors=18
      mformat_only

The following shorthand geometry descriptions are available:

1.44m
high density 3 1/2 disk. Equivalent to: fat_bits=12 cylinders=80 heads=2 sectors=18
1.2m
high density 5 1/4 disk. Equivalent to: fat_bits=12 cylinders=80 heads=2 sectors=15
720k
double density 3 1/2 disk. Equivalent to: fat_bits=12 cylinders=80 heads=2 sectors=9
360k
double density 5 1/4 disk. Equivalent to: fat_bits=12 cylinders=40 heads=2 sectors=9

The shorthand format descriptions may be amended. For example, 360k sectors=8 describes a 320k disk and is equivalent to: fat_bits=12 cylinders=40 heads=2 sectors=8

3.5.4 Open Flags

Moreover, the following flags are available:

sync
All i/o operations are done synchronously
nodelay
The device or file is opened with the O_NDELAY flag. This is needed on some non-Linux architectures.
exclusive
The device or file is opened with the O_EXCL flag. On Linux, this ensures exclusive access to the floppy drive. On most other architectures, and for plain files it has no effect at all.


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

3.5.5 General Purpose Drive Variables

The following general purpose drive variables are available. Depending to their type, these variables can be set to a string (precmd) or an integer (all others)

fat_bits
The number of FAT bits. This may be 12 or 16. This is very rarely needed, as it can almost always be deduced from information in the boot sector. On the contrary, describing the number of fat bits may actually be harmful if you get it wrong. You should only use it if mtools gets the autodetected number of fat bits wrong, or if you want to mformat a disk with a weird number of fat bits.

Describes the DOS codepage used for short filenames. This is a number between 1 and 999. By default, codepage 850 is used. The reason for this is because this codepage contains most of the characters that are also available in ISO-Latin-1. You may also specify a global codepage for all drives by using the global default_codepage parameter (outside of any drive description). This parameters exists starting at version 4.0.0
precmd
On some variants of Solaris, it is necessary to call 'volcheck -v' before opening a floppy device, in order for the system to notice that there is indeed a disk in the drive. precmd="volcheck -v" in the drive clause establishes the desired behavior.

blocksize
This parameter represents a default block size to be always used on this device. All I/O is done with multiples of this block size, independantly of the sector size registered in the filesystem's boot sector. This is useful for character devices whose sector size is not 512, such as for example CD Rom drives on Solaris.

Only the file variable is mandatory. The other parameters may be left out. In that case a default value or an autodetected value is used.

3.5.6 General Purpose Drive Flags

A flag can either be set to 1 (enabled) or 0 (disabled). If the value is ommitted, it is enabled. For example, scsi is equivalent to scsi=1

nolock
Instruct mtools to not use locking on this drive. This is needed on systems with buggy locking semantics. However, enabling this makes operation less safe in cases where several users may access the same drive at the same time.

scsi
When set to 1, this option tells mtools to use raw SCSI I/O instead of the standard read/write calls to access the device. Currently, this is supported on HP/UX, Solaris and SunOs. This is needed because on some architectures, such as SunOs or Solaris, PC media can't be accessed using the read and write syscalls, because the OS expects them to contain a Sun specific "disk label".

As raw Scsi access always uses the whole device, you need to specify the "partition" flag in addition

On some architectures, such as Solaris, mtools needs root privileges to be able to use the scsi option. Thus mtools should be installed set uid root on Solaris if you want to access Zip/Jaz drives. Thus, if the scsi flag is given, privileged is automatically implied, unless explicitly disabled by privileged=0

Mtools uses its root privileges to open the device, and to issue the actual SCSI I/O calls. Moreover, root privileges are only used for drives described in a system-wide configuration file such as `/usr/local/etc/mtools.conf', and not for those described in `~/.mtoolsrc' or `$MTOOLSRC'.

privileged
When set to 1, this instructs mtools to use its set-uid and set-gid privileges for opening the given drive. This option is only valid for drives described in the system-wide configuration files (such as `/usr/local/etc/mtools.conf', not `~/.mtoolsrc' or `$MTOOLSRC'). Obviously, this option is also a no op if mtools is not installed setuid or setgid. This option is implied by 'scsi=1', but again only for drives defined in system-wide configuration files. Privileged may also be set explicitely to 0, in order to tell mtools not to use its privileges for a given drive even if scsi=1 is set.

Mtools only needs to be installed setuid if you use the privileged or scsi drive variables. If you do not use these options, mtools works perfectly well even when not installed setuid root.

vold

Instructs mtools to interpret the device name as a vold identifier rather than as a filename. The vold identifier is translated into a real filename using the media_findname() and media_oldaliases() functions of the volmgt library. This flag is only available if you configured mtools with the --enable-new-vold option before compilation.

swap

Consider the media as a word-swapped Atari disk.

use_xdf
If this is set to a non-zero value, mtools also tries to access this disk as an XDF disk. XDF is a high capacity format used by OS/2. This is off by default. See section 2.7.4 XDF, for more details.
mformat_only
Tells mtools to use the geometry for this drive only for mformatting and not for filtering.

filter
Tells mtools to use the geometry for this drive both for mformatting and filtering.

remote
Tells mtools to connect to floppyd (see section 4.1 Floppyd).

3.5.7 Supplying multiple descriptions for a drive

It is possible to supply multiple descriptions for a drive. In that case, the descriptions are tried in order until one is found that fits. Descriptions may fail for several reasons:

  1. because the geometry is not appropriate,
  2. because there is no disk in the drive,
  3. or because of other problems.

Multiple definitions are useful when using physical devices which are only able to support one single disk geometry. Example:
 
  drive a: file="/dev/fd0H1440" 1.44m
  drive a: file="/dev/fd0H720" 720k

This instructs mtools to use /dev/fd0H1440 for 1.44m (high density) disks and /dev/fd0H720 for 720k (double density) disks. On Linux, this feature is not really needed, as the /dev/fd0 device is able to handle any geometry.

You may also use multiple drive descriptions to access both of your physical drives through one drive letter:

 
  drive z: file="/dev/fd0"
  drive z: file="/dev/fd1"

With this description, mdir z: accesses your first physical drive if it contains a disk. If the first drive doesn't contain a disk, mtools checks the second drive.

When using multiple configuration files, drive descriptions in the files parsed last override descriptions for the same drive in earlier files. In order to avoid this, use the drive+ or +drive keywords instead of drive. The first adds a description to the end of the list (i.e. it will be tried last), and the first adds it to the start of the list.


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

3.6 Location of configuration files and parsing order

The configuration files are parsed in the following order:

  1. compiled-in defaults
  2. `/usr/local/etc/mtools.conf'
  3. `/etc/mtools' This is for backwards compatibility only, and is only parsed if `mtools.conf' doesn't exist.
  4. `~/.mtoolsrc'.
  5. `$MTOOLSRC' (file pointed by the MTOOLSRC environmental variable)

Options described in the later files override those described in the earlier files. Drives defined in earlier files persist if they are not overridden in the later files. For instance, drives A and B may be defined in `/usr/local/etc/mtools.conf' and drives C and D may be defined in `~/.mtoolsrc' However, if `~/.mtoolsrc' also defines drive A, this new description would override the description of drive A in `/usr/local/etc/mtools.conf' instead of adding to it. If you want to add a new description to a drive already described in an earlier file, you need to use either the +drive or drive+ keyword.

3.7 Backwards compatibility with old configuration file syntax

The syntax described herein is new for version mtools-3.0. The old line-oriented syntax is still supported. Each line beginning with a single letter is considered to be a drive description using the old syntax. Old style and new style drive sections may be mixed within the same configuration file, in order to make upgrading easier. Support for the old syntax will be phased out eventually, and in order to discourage its use, I purposefully omit its description here.

4.1 Floppyd

Floppyd is used as a server to grant access to the floppy drive to clients running on a remote machine, just as an X server grants access to the display to remote clients. It has the following syntax:

floppyd [-d] [-l] [-s port] [-r user] [-b ipaddr] [-x display] devicenames

floppyd is always associated with an X server. It runs on the same machine as its X server, and listens on port 5703 and above.


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

4.1.1 Authentication

floppyd authenticates remote clients using the Xauthority protocol. Xhost authentication is not supported. Each floppyd is associated with an X server. When a remote client attempts to connect to floppyd, it sends floppyd the X authority record corresponding to floppyd's X server. Floppyd in turn then tries to open up a connection to the X server in order to verify the authenticity of the xauth record. If the connection to the X server succeeds, the client is granted access. DISPLAY.

Caution: In order to make authentication work correctly, the local host should not be listed in the xhost list of allowed hosts. Indeed, hosts listed in xhost do not need a correct Xauthority cookie to connect to the X server. As floppyd runs on the same host as the X server, all its probe connection would succeed even for clients who supplied a bad cookie. This means that your floppy drive would be open to the world, i.e. a huge security hole. If your X server does not allow you to remove localhost:0 and :0 from the xhost list, you can prevent floppyd from probing those display names with the -l option.


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

4.1.2 Command line options

d
Daemon mode. Floppyd runs its own server loop. Do not supply this if you start floppyd from inetd.conf
s port
Port number for deamon mode. Default is 5703 + displaynumber. This flag implies daemon mode. For example, for display hitchhiker:5, the port would be 5708.
b ipaddr
Bind address (for multihomed hosts). This flag implies daemon mode
r user
Run the server under as the given user
x display
X display to use for authentication. By default, this is taken from the DISPLAY variable. If neither the x attribute is present nor DISPLAY is set, floppyd uses :0.0.

devicenames is a list of device nodes to be opened. Default is /dev/fd0. Multiple devices are only supported on mtools versions newer than 3.9.11.


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

4.1.3 Connecting to floppyd

In order to use floppyd, add the flag remote to the device description in your `~/.mtoolsrc' file. If the flag remote is given, the file parameter of the device description is taken to be a remote address. It's format is the following: hostname:displaynumber[/[baseport][/drive]]. When using this entry, mtools connects to port baseport+displaynumber at hostname. By default baseport is 5703. The drive parameter is to distinguish among multiple drives associated with a single display (only mtools versions more recent than 3.9.11)


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

4.1.4 Examples:

The following starts a floppy daemon giving access to `/dev/fd0', listening on the default port 5703, tied to the default X servers:

 
floppyd -d /dev/fd0

Each of the following starts a floppy daemon giving access to `/dev/fd1', tied to the :1 local X servers, and listening on port 5704. We assume that the local host is named hitchhiker.

 
floppyd -d /dev/fd0
floppyd -d -x :1 -p 5704 /dev/fd0 

If you want to start floppyd by inetd instead of running it as a daemon, insert the following lines into `/etc/services':
 
# floppy daemon
floppyd-0    5703/tcp    # floppy daemon for X server :0
floppyd-1    5704/tcp    # floppy daemon for X server :1

And insert the following into `/etc/inetd.conf' (assuming that you have defined a user named floppy in your `/etc/passwd'):

 
# floppy daemon
floppyd-0 stream  tcp  wait  floppy  /usr/sbin/floppyd floppyd /dev/fd0 
floppyd-1 stream  tcp  wait  floppy  /usr/sbin/floppyd floppyd -x :1 /dev/fd0 

Note that you need to supply the X display names for the second floppyd. This is because the port is opened by inetd.conf, and hence floppyd cannot know its number to interfere the display number.

On the client side, insert the following into your `~/.mtoolsrc' to define a drive letter accessing floppy drive in your X terminal:
 
drive x: file="$DISPLAY" remote

If your X terminal has more than one drive, you may access the additional drives as follows:
 
drive y: file="$DISPLAY//1" remote
drive z: file="$DISPLAY//2" remote

4.2 Floppyd_installtest

Floppyd_installtest is used to check for the presence of a running floppyd daemon. This is usefull, if you have a small frontend script to mtools, which decides whether to use floppyd or not.

floppyd_installtest [-f] Connect-String

If the -f option is specified, floppyd_installtest does a full X-Cookie authentication and complains if this does not work.

The connect-String has the format described in the floppyd-section: hostname:displaynumber[/baseport]

4.3 Mattrib

Mattrib is used to change MS-DOS file attribute flags. It has the following syntax:

mattrib [-a|+a] [-h|+h] [-r|+r] [-s|+s] [-/] [-p] [-X] msdosfile [ msdosfiles ... ]

Mattrib adds attribute flags to an MS-DOS file (with the `+' operator) or remove attribute flags (with the `-' operator).

Mattrib supports the following attribute bits:

a
Archive bit. Used by some backup programs to indicate a new file.
r
Read-only bit. Used to indicate a read-only file. Files with this bit set cannot be erased by DEL nor modified.
s
System bit. Used by MS-DOS to indicate a operating system file.
h
Hidden bit. Used to make files hidden from DIR.

Mattrib supports the following command line flags:

/
Recursive. Recursively list the attributes of the files in the subdirectories.
X
Concise. Prints the attributes whithout any whitespace padding. If neither the "/" option is given, nor the msdosfile contains a wildcard, and there is only one Msdos file parameter on the command line, only the attribute is printed, and not the filename. This option is convenient for scripts
p
Replay mode. Outputs a series of mformat commands that will reproduce the current situation, starting from a situation as left by untarring the Dos filesystem. Commands are only output for attribute settings that differ from the default (archive bit set for files, unset for directories). This option is intended to be used in addition to tar. The readonly attribute is not taken into account, as tar can set that one itself.

4.4 Mbadblocks

The mbadblocks command is used to scan an MS-DOS floppy and mark its unused bad blocks as bad. It uses the following syntax:

mbadblocks drive:

Mbadblocks scans an MS-DOS floppy for bad blocks. All unused bad blocks are marked as such in the FAT. This is intended to be used right after mformat. It is not intended to salvage bad disks.


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

4.4.1 Bugs

Mbadblocks should (but doesn't yet :-( ) also try to salvage bad blocks which are in use by reading them repeatedly, and then mark them bad.


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

4.5 Mcat

The mcat command is used to copy an entire disk image from or to the floppy device. It uses the following syntax:

mcat [-w] drive:

Mcat performs the same task as the unix cat command. It is included into the mtools package, since cat cannot access remote floppy devices offered by the mtools floppy daemon. Now it is possible to create boot floppies remotely.

The default operation is reading. The output is written to stdout.

If the -w option is specified, mcat reads a disk-image from stdin and writes it to the given device. Use this carefully! Because of the lowlevel nature of this command, it will happily destroy any data written before on the disk without warning!


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

4.6 Mcd

The mcd command is used to change the mtools working directory on the MS-DOS disk. It uses the following syntax:

 
mcd [msdosdirectory]

Without arguments, mcd reports the current device and working directory. Otherwise, mcd changes the current device and current working directory relative to an MS-DOS filesystem.

The environmental variable MCWD may be used to locate the file where the device and current working directory information is stored. The default is `$HOME/.mcwd'. Information in this file is ignored if the file is more than 6 hours old.

Mcd returns 0 on success or 1 on failure.

Unlike MS-DOS versions of CD, mcd can be used to change to another device. It may be wise to remove old `.mcwd' files at logout.

4.7 Mclasserase

The mclasserase command is used to wipe memory cards by overwriting it three times: first with 0xff, then with 0x00, then with 0xff again. The command uses the following syntax:

 
mclasserase [-d] msdosdrive

Dos drive is optional, if none is specified, use A:. If more than one drive are specified, all but the last are ignored.

Mclasserase accepts the following command line options:

d
Stop after each erase cycle, for testing purposes
p
Not yet implemented

Mclasserase returns 0 on success or -1 on failure.


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

4.8 Mcopy

The mcopy command is used to copy MS-DOS files to and from Unix. It uses the following syntax:

 
mcopy [-bspanvmQT] [-D clash_option] sourcefile targetfile
mcopy [-bspanvmQT] [-D clash_option] sourcefile [ sourcefiles... ] targetdirectory
mcopy [-tnvm] MSDOSsourcefile

Mcopy copies the specified file to the named file, or copies multiple files to the named directory. The source and target can be either MS-DOS or Unix files.

The use of a drive letter designation on the MS-DOS files, 'a:' for example, determines the direction of the transfer. A missing drive designation implies a Unix file whose path starts in the current directory. If a source drive letter is specified with no attached file name (e.g. mcopy a: .), all files are copied from that drive.

If only a single, MS-DOS source parameter is provided (e.g. "mcopy a:foo.exe"), an implied destination of the current directory (`.') is assumed.

A filename of `-' means standard input or standard output, depending on its position on the command line.

Mcopy accepts the following command line options:

t
Text file transfer. Mcopy translates incoming carriage return/line feeds to line feeds when copying from Dos to Unix, and vice-versa when copying from Unix to Dos.
b
Batch mode. Optimized for huge recursive copies, but less secure if a crash happens during the copy.
s
Recursive copy. Also copies directories and their contents
p
Preserves the attributes of the copied files
Q
When mcopying multiple files, quits as soon as one copy fails (for example due to lacking storage space on the target disk)
a
Text (Ascii) file transfer. Mcopy translates incoming carriage return/line feeds to line feeds.
T
Text (Ascii) file transfer with charset conversion. Differs from -a in the Mcopy also translates incoming PC-8 characters to ISO-8859-1 equivalents as far as possible. When reading DOS files, untranslatable characters are replaced by '#'; when writing DOS files, untranslatable characters are replaced by '.'.
n
No confirmation when overwriting Unix files. Mcopy doesn't warn the user when overwriting an existing Unix file. If the target file already exists, and the -n option is not in effect, mcopy asks whether to overwrite the file or to rename the new file (2.5 Name clashes) for details). In order to switch off confirmation for DOS files, use -o.
m
Preserve the file modification time.
v
Verbose. Displays the name of each file as it is copied.

4.8.1 Bugs

Unlike MS-DOS, the '+' operator (append) from MS-DOS is not supported. However, you may use mtype to produce the same effect:
 
mtype a:file1 a:file2 a:file3 >unixfile
mtype a:file1 a:file2 a:file3 | mcopy - a:msdosfile

4.9 Mdel

The mdel command is used to delete an MS-DOS file. Its syntax is:

 
mdel [-v] msdosfile [ msdosfiles ...  ]

Mdel deletes files on an MS-DOS filesystem.

Mdel asks for verification prior to removing a read-only file.


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

4.10 Mdeltree

The mdeltree command is used to delete an MS-DOS file. Its syntax is:

 
mdeltree [-v] msdosdirectory [msdosdirectories...]

Mdeltree removes a directory and all the files and subdirectories it contains from an MS-DOS filesystem. An error occurs if the directory to be removed does not exist.


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

4.11 Mdir

The mdir command is used to display an MS-DOS directory. Its syntax is:

mdir [-/] [-f] [-w] [-a] [-b] msdosfile [ msdosfiles...]

Mdir displays the contents of MS-DOS directories, or the entries for some MS-DOS files.

Mdir supports the following command line options:

/
Recursive output, just like Dos' -s option
w
Wide output. With this option, mdir prints the filenames across the page without displaying the file size or creation date.
a
Also list hidden files.
f
Fast. Do not try to find out free space. On larger disks, finding out the amount of free space takes up some non trivial amount of time, as the whole FAT must be read in and scanned. The -f flag bypasses this step. This flag is not needed on FAT32 filesystems, which store the size explicitely.
b
Concise listing. Lists each directory name or filename, one per line (including the filename extension). This switch displays no heading information and no summary. Only a newline separated list of pathnames is displayed.

An error occurs if a component of the path is not a directory.

4.12 Mdu

Mdu is used to list the space occupied by a directory, its subdirectories and its files. It is similar to the du command on Unix. The unit used are clusters. Use the minfo command to find out the cluster size.

mdu [-a] [ msdosfiles ... ]

a
All files. List also the space occupied for individual files.
s
Only list the total space, don't give details for each subdirectory.

4.13 Mformat

The mformat command is used to add an MS-DOS filesystem to a low-level formatted diskette. Its syntax is:

 
mformat [-t cylinders] [-h heads] [-s sectors]
  [-f size] [-1] [-4] [-8]
  [-v volume_label]
  [-F] [-S sizecode] [-X]
  [-2 sectors_on_track_0] [-3]
  [-0 rate_on_track_0] [-A rate_on_other_tracks]
  [-M software_sector_size]
  [-N serial_number] [-a]
  [-C] [-H hidden_sectors] [-I fsVersion]
  [-r root_sectors] [-L fat_len] 
  [-B boot_sector] [-k]
  [-m media_descriptor]
  drive:

Mformat adds a minimal MS-DOS filesystem (boot sector, FAT, and root directory) to a diskette that has already been formatted by a Unix low-level format.

The following options are supported: (The S, 2, 1 and M options may not exist if this copy of mtools has been compiled without the USE_2M option)

The following options are the same as for Dos's format command:

v
Specifies the volume label. A volume label identifies the disk and can be a maximum of 11 characters. If you omit the -v switch, mlabel will assign no label to the disk.
f
Specifies the size of the DOS filesystem to format. Only a certain number of predefined sizes are supported by this flag; for others use the -h/-t/-s flags. The following sizes are supported:
160
160K, single-sided, 8 sectors per track, 40 cylinders (for 5 1/4 DD)
180
160K, single-sided, 9 sectors per track, 40 cylinders (for 5 1/4 DD)
320
320K, double-sided, 8 sectors per track, 40 cylinders (for 5 1/4 DD)
360
360K, double-sided, 9 sectors per track, 40 cylinders (for 5 1/4 DD)
720
720K, double-sided, 9 sectors per track, 80 cylinders (for 3 1/2 DD)
1200
1200K, double-sided, 15 sectors per track, 80 cylinders (for 5 1/4 HD)
1440
1440K, double-sided, 18 sectors per track, 80 cylinders (for 3 1/2 HD)
2880
2880K, double-sided, 36 sectors per track, 80 cylinders (for 3 1/2 ED)

t
Specifies the number of tracks on the disk.
h
The number of heads (sides).
n
Specifies the number of sectors per track. If the 2m option is given, number of 512-byte sector equivalents on generic tracks (i.e. not head 0 track 0). If the 2m option is not given, number of physical sectors per track (which may be bigger than 512 bytes).

1
Formats a single side (equivalent to -h 1)

4
Formats a 360K double-sided disk (equivalent to -f 360). When used together with -the 1 switch, this switch formats a 180K disk

8
Formats a disk with 8 sectors per track.

MSDOS format's q, u and b options are not supported, and s has a different meaning.

The following options are specific to mtools:

F
Format the partition as FAT32.

S
The sizecode. The size of the sector is 2 ^ (sizecode + 7).
X
formats the disk as an XDF disk. See section 2.7.4 XDF, for more details. The disk has first to be low-level formatted using the xdfcopy utility included in the fdutils package. XDF disks are used for instance for OS/2 install disks.
2
2m format. The parameter to this option describes the number of sectors on track 0, head 0. This option is recommended for sectors bigger than normal.
3
don't use a 2m format, even if the current geometry of the disk is a 2m geometry.
0
Data transfer rate on track 0
A
Data transfer rate on tracks other than 0
M
software sector size. This parameter describes the sector size in bytes used by the MS-DOS filesystem. By default it is the physical sector size.
N
Uses the requested serial number, instead of generating one automatically
a
If this option is given, an Atari style serial number is generated. Ataris store their serial number in the OEM label.
C
creates the disk image file to install the MS-DOS filesystem on it. Obviously, this is useless on physical devices such as floppies and hard disk partitions, but is interesting for image files.
H
number of hidden sectors. This parameter is useful for formatting hard disk partition, which are not aligned on track boundaries (i.e. first head of first track doesn't belong to the partition, but contains a partition table). In that case the number of hidden sectors is in general the number of sectors per cylinder. This is untested.
I
Sets the fsVersion id when formatting a FAT32 drive. In order to find this out, run minfo on an existing FAT32 drive, and mail me about it, so I can include the correct value in future versions of mtools.
c
Sets the size of a cluster (in sectors). If this cluster size would generate a FAT that too big for its number of bits, mtools automatically increases the cluster size, until the FAT is small enough.
d
Sets the number of FAT copies. Default is 2. This setting can also be specified using the MTOOLS_NFATS environment variable.
r
Sets the size of the root directory (in sectors). Only applicable to 12 and 16 bit FATs. This setting can also be specified using the MTOOLS_DIR_LEN environment variable.
L
Sets the length of the FAT.
B
Use the bootsector stored in the given file or device, instead of using its own. Only the geometry fields are updated to match the target disks parameters.
k
Keep the existing boot sector as much as possible. Only the geometry fields and other similar filesystem data are updated to match the target disks parameters.

m
Use a non-standard media descriptor byte for this disk. The media descriptor is stored at position 21 of the boot sector, and as first byte in each FAT copy. Using this option may confuse DOS or older mtools version, and may make the disk unreadable. Only use if you know what you are doing.

To format a diskette at a density other than the default, you must supply (at least) those command line parameters that are different from the default.

Mformat returns 0 on success or 1 on failure.

It doesn't record bad block information to the Fat, use mbadblocks for that.

4.14 Mkmanifest

The mkmanifest command is used to create a shell script (packing list) to restore Unix filenames. Its syntax is:

mkmanifest [ files ]

Mkmanifest creates a shell script that aids in the restoration of Unix filenames that got clobbered by the MS-DOS filename restrictions. MS-DOS filenames are restricted to 8 character names, 3 character extensions, upper case only, no device names, and no illegal characters.

The mkmanifest program is compatible with the methods used in pcomm, arc, and mtools to change perfectly good Unix filenames to fit the MS-DOS restrictions. This command is only useful if the target system which will read the diskette cannot handle vfat long names.


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

4.14.1 Example

You want to copy the following Unix files to a MS-DOS diskette (using the mcopy command).

 
  very_long_name
  2.many.dots
  illegal:
  good.c
  prn.dev
  Capital

Mcopy converts the names to:

 
  very_lon
  2xmany.dot
  illegalx
  good.c
  xprn.dev
  capital

The command:
 
mkmanifest very_long_name 2.many.dots illegal: good.c prn.dev Capital >manifest
would produce the following:
 
  mv very_lon very_long_name
  mv 2xmany.dot 2.many.dots
  mv illegalx illegal:
  mv xprn.dev prn.dev
  mv capital Capital

Notice that "good.c" did not require any conversion, so it did not appear in the output.

Suppose I've copied these files from the diskette to another Unix system, and I now want the files back to their original names. If the file "manifest" (the output captured above) was sent along with those files, it could be used to convert the filenames.

4.14.2 Bugs

The short names generated by mkmanifest follow the old convention (from mtools-2.0.7) and not the one from Windows 95 and mtools-3.0.

4.15 Minfo

The minfo command prints the parameters of a Dos filesystem, such as number of sectors, heads and cylinders. It also prints an mformat command line which can be used to create a similar Dos filesystem on another media. However, this doesn't work with 2m or Xdf media, and with Dos 1.0 filesystems
 
minfo drive:

Mlabel supports the following option:

v
Prints a hexdump of the bootsector, in addition to the other information

4.16 Mlabel

The mlabel command adds a volume label to a disk. Its syntax is:
 
mlabel [-vcsn] [-N serial] drive:[new_label]

Mlabel displays the current volume label, if present. If new_label is not given, and if neither the c nor the s options are set, it prompts the user for a new volume label. To delete an existing volume label, press return at the prompt.

Reasonable care is taken to create a valid MS-DOS volume label. If an invalid label is specified, mlabel changes the label (and displays the new label if the verbose mode is set). Mlabel returns 0 on success or 1 on failure.

Mlabel supports the following options:

c
Clears an existing label, without prompting the user
s
Shows the existing label, without prompting the user.
n
Assigns a new (random) serial number to the disk
N serial
Sets the supplied serial number. The serial number should be supplied as an 8 digit hexadecimal number, without spaces

4.17 Mmd

The mmd command is used to make an MS-DOS subdirectory. Its syntax is:

mmd [-D clash_option] msdosdirectory [ msdosdirectories... ]

Mmd makes a new directory on an MS-DOS filesystem. An error occurs if the directory already exists.


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

4.18 Mmount

The mmount command is used to mount an MS-DOS disk. It is only available on Linux, as it is only useful if the OS kernel allows to configure the disk geometry. Its syntax is:

mmount msdosdrive [mountargs]

Mmount reads the boot sector of an MS-DOS disk, configures the drive geometry, and finally mounts it passing mountargs to mount. If no mount arguments are specified, the name of the device is used. If the disk is write protected, it is automatically mounted read only.

4.19 Mmove

The mmove command is used to moves or renames an existing MS-DOS file or subdirectory.
 
mmove [-v] [-D clash_option] sourcefile targetfile
mmove [-v]  [-D clash_option] sourcefile [ sourcefiles... ] targetdirectory
Mmove moves or renames an existing MS-DOS file or subdirectory. Unlike the MS-DOS version of MOVE, mmove is able to move subdirectories. Files or directories can only be moved within one filesystem. Data cannot be moved from Dos to Unix or vice-versa. If you omit the drive letter from the target file or directory, the same letter as for the source is assumed. If you omit the drive letter from all parameters, drive a: is assumed by default.

4.20 Mpartition

The mpartition command is used to create MS-DOS filesystems as partitions. This is intended to be used on non-Linux systems, i.e. systems where fdisk and easy access to Scsi devices are not available. This command only works on drives whose partition variable is set.

 
mpartition -p drive
mpartition -r drive
mpartition -I [-B bootSector] drive 
mpartition -a drive
mpartition -d drive
mpartition -c [-s sectors] [-h heads]
[-t cylinders] [-v [-T type] [-b
begin] [-l length] [-f]

Mpartition supports the following operations:

p
Prints a command line to recreate the partition for the drive. Nothing is printed if the partition for the drive is not defined, or an inconsistency has been detected. If verbose (-v) is also set, prints the current partition table.
r
Removes the partition described by drive.
I
Initializes the partition table, and removes all partitions.
c
Creates the partition described by drive.
a
"Activates" the partition, i.e. makes it bootable. Only one partition can be bootable at a time.
d
"Desactivates" the partition, i.e. makes it unbootable.

If no operation is given, the current settings are printed.

For partition creations, the following options are available:

s sectors
The number of sectors per track of the partition (which is also the number of sectors per track for the whole drive).
h heads
The number of heads of the partition (which is also the number of heads for the whole drive). By default, the geometry information (number of sectors and heads) is figured out from neighbouring partition table entries, or guessed from the size.
t cylinders
The number of cylinders of the partition (not the number of cylinders of the whole drive.
b begin
The starting offset of the partition, expressed in sectors. If begin is not given, mpartition lets the partition begin at the start of the disk (partition number 1), or immediately after the end of the previous partition.
l length
The size (length) of the partition, expressed in sectors. If end is not given, mpartition figures out the size from the number of sectors, heads and cylinders. If these are not given either, it gives the partition the biggest possible size, considering disk size and start of the next partition.

The following option is available for all operation which modify the partition table:

f
Usually, before writing back any changes to the partition, mpartition performs certain consistenct checks, such as checking for overlaps and proper alignment of the partitions. If any of these checks fails, the partition table is not changes. The -f allows you to override these safeguards.

The following options are available for all operations:

v
Together with -p prints the partition table as it is now (no change operation), or as it is after it is modified.
vv
If the verbosity flag is given twice, mpartition will print out a hexdump of the partition table when reading it from and writing it to the device.

The following option is available for partition table initialization:

B bootSector
Reads the template master boot record from file bootSector.

4.21 Mrd

The mrd command is used to remove an MS-DOS subdirectory. Its syntax is:

 
mrd [-v] msdosdirectory [ msdosdirectories... ]

Mrd removes a directory from an MS-DOS filesystem. An error occurs if the directory does not exist or is not empty.


[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ]

4.22 Mren

The mren command is used to rename or move an existing MS-DOS file or subdirectory. Its syntax is:

 
mren [-voOsSrRA] sourcefile targetfile

Mren renames an existing file on an MS-DOS filesystem.

In verbose mode, Mren displays the new filename if the name supplied is invalid.

If the first syntax is used (only one sourcefile), and if the target name doesn't contain any slashes or colons, the file (or subdirectory) is renamed in the same directory, instead of being moved to the current mcd directory as would be the case with mmove. Unlike the MS-DOS version of REN, mren can be used to rename directories.

4.24 Mtoolstest

The mtoolstest command is used to tests the mtools configuration files. To invoke it, just type mtoolstest without any arguments. Mtoolstest reads the mtools configuration files, and prints the cumulative configuration to stdout. The output can be used as a configuration file itself (although you might want to remove redundant clauses). You may use this program to convert old-style configuration files into new style configuration files.

4.25 Mtype

The mtype command is used to display contents of an MS-DOS file. Its syntax is:

 
mtype [-ts] msdosfile [ msdosfiles... ]

Mtype displays the specified MS-DOS file on the screen.

In addition to the standard options, Mtype allows the following command line options:

t
Text file viewing. Mtype translates incoming carriage return/line feeds to line feeds.
s
Mtype strips the high bit from the data.

The mcd command may be used to establish the device and the current working directory (relative to MS-DOS), otherwise the default is A:/.

Mtype returns 0 on success, 1 on utter failure, or 2 on partial failure.

Unlike the MS-DOS version of TYPE, mtype allows multiple arguments.

4.26 Mzip

The mzip command is used to issue ZIP disk specific commands on Linux, Solaris or HPUX. Its syntax is:

 
mzip [-epqrwx]

Mzip allows the following command line options:

e
Ejects the disk.
f
Force eject even if the disk is mounted (must be given in addition to -e).
r
Write protect the disk.
w
Remove write protection.
p
Password write protect.
x
Password protect
u
Temporarily unprotect the disk until it is ejected. The disk becomes writable, and reverts back to its old state when ejected.
q
Queries the status

To remove the password, set it to one of the passwordless modes -r or -w: mzip will then ask you for the password, and unlock the disk. If you have forgotten the password, you can get rid of it by low-level formatting the disk (using your SCSI adaptor's BIOS setup).

The ZipTools disk shipped with the drive is also password protected. On Dos or on a Mac, this password is automatically removed once the ZipTools have been installed. From various articles posted to Usenet, I learned that the password for the tools disk is APlaceForYourStuff(1). Mzip knows about this password, and tries it first, before prompting you for a password. Thus mzip -w z: unlocks the tools disk(2). The tools disk is formatted in a special way so as to be usable both in a PC and in a Mac. On a PC, the Mac filesystem appears as a hidden file named `partishn.mac'. You may erase it to reclaim the 50 Megs of space taken up by the Mac filesystem.

4.26.1 Bugs

This command is a big kludge. A proper implementation would take a rework of significant parts of mtools, but unfortunately I don't have the time for this right now. The main downside of this implementation is that it is inefficient on some architectures (several successive calls to mtools, which defeats mtools' caching).

5. Architecture specific compilation flags

To compile mtools, first invoke ./configure before make. In addition to the standard autoconfigure flags, there are two architecture specific flags available.

./configure --enable-xdf
./configure --disable-xdf
Enables support for XDF disks. This is on by default. See section 2.7.4 XDF, for details.
./configure --enable-vold
./configure --disable-vold
Enables support for vold on Solaris. When used in conjunction with vold, mtools should use different device nodes than for direct access.

./configure --enable-new-vold
./configure --disable-new-vold
Enables new support for vold on Solaris. This is supposed to work more smoothly than the old support.

./configure --enable-floppyd
./configure --disable-floppyd
Enables support for floppyd. By default, floppyd support is enabled as long as the necessary X includes and libraries are available.

6. Porting mtools to architectures which are not supported yet

This chapter is only interesting for those who want to port mtools to an architecture which is not yet supported. For most common systems, default drives are already defined. If you want to add default drives for a still unsupported system, run config.guess, to see which identification autoconf uses for that system. This identification is of the form cpu-vendor-os (for example sparc-sun-sunos). The cpu and the os parts are passed to the compiler as preprocessor flags. The OS part is passed to the compiler in three forms.

  1. The complete os name, with dots replaced by underscores. sco3.2v2 would yield sco3_2v2
  2. The base os name. Sco3.2v2 would yield Sco
  3. The base os name plus its major version. Sco3.2v2 would yield Sco3

All three versions are passed, if they are different.

To define the devices, use the entries for the systems that are already present as templates. In general, they have the following form:

 
#if (defined (my_cpu) && defined(my_os))
#define predefined_devices
struct device devices[] = {
        { "/dev/first_drive", 'drive_letter', drive_description},
        ... 
        { "/dev/last_drive", 'drive_letter', drive_description}
}
#define INIT_NOOP
#endif

"/dev/first_drive" is the name of the device or image file representing the drive. Drive_letter is a letter ranging from a to z giving access to the drive. Drive_description describes the type of the drive:

ED312
extra density (2.88M) 3 1/2 disk
HD312
high density 3 1/2 disk
DD312
double density 3 1/2 disk
HD514
high density 5 1/4 disk
DD514
double density 5 1/4 disk
DDsmall
8 sector double density 5 1/4 disk
SS514
single sided double density 5 1/4 disk
SSsmall
single sided 8 sector double density 5 1/4 disk
GENFD
generic floppy drive (12 bit FAT)
GENHD
generic hard disk (16 bit FAT)
GEN
generic device (all parameters match)
ZIPJAZ(flags)
generic ZIP drive using normal access. This uses partition 4. Flags are any special flags to be passed to open.
RZIPJAZ(flags)
generic ZIP drive using raw SCSI access. This uses partition 4. Flags are any special flags to be passed to open.
REMOTE
the remote drive used for floppyd. Unlike the other items, this macro also includes the file name ($DISPLAY) and the drive letter (X)

Entries may be described in more detail:
 
 fat_bits,open_flags,cylinders,heads,sectors,DEF_ARG
or, if you need to describe an offset (filesystem doesn't start at beginning of filesystem)
 
 fat_bits, open_flags, cylinders, heads, sectors, offset, DEF_ARG0

fat_bits
is either 12, 16 or 0. 0 means that the device accepts both types of FAT.
open_flags
may include flags such as O_NDELAY, or O_RDONLY, which might be necessary to open the device. 0 means no special flags are needed.
cylinders,heads,sectors
describe the geometry of the disk. If cylinders is 0, the heads and sectors parameters are ignored, and the drive accepts any geometry.
offset
is used if the DOS filesystem doesn't begin at the start of the device or image file. This is mostly useful for Atari Ram disks (which contain their device driver at the beginning of the file) or for DOS emulator images (which may represent a partitioned device.

Definition of defaults in the devices file should only be done if these same devices are found on a large number of hosts of this type. In that case, could you also let me know about your new definitions, so that I can include them into the next release. For purely local file, I recommend that you use the /usr/local/etc/mtools.conf and ~/.mtoolsrc configuration files.

However, the devices files also allows to supply geometry setting routines. These are necessary if you want to access high capacity disks.

Two routines should be supplied:

  1. Reading the current parameters
     
    static inline int get_parameters(int fd, struct generic_floppy_struct *floppy)
    

    This probes the current configured geometry, and return it in the structure generic_floppy_struct (which must also be declared). Fd is an open file descriptor for the device, and buf is an already filled in stat structure, which may be useful. This routine should return 1 if the probing fails, and 0 otherwise.

  2. Setting new parameters
     
    static inline int set_parameters(int fd, struct generic_floppy_struct *floppy)
                                     struct stat *buf)
    
    This configures the geometry contained in floppy on the file descriptor fd. Buf is the result of a stat call (already filled in). This should return 1 if the new geometry cannot be configured, and 0 otherwise.

A certain number of preprocessor macros should also be supplied:

TRACKS(floppy)
refers to the track field in the floppy structure
HEADS(floppy)
refers to the heads field in the floppy structure
SECTORS(floppy)
refers to the sectors per track field in the floppy structure
SECTORS_PER_DISK(floppy)
refers to the sectors per disk field in the floppy structure (if applicable, otherwise leave undefined)

BLOCK_MAJOR
major number of the floppy device, when viewed as a block device

CHAR_MAJOR
major number of the floppy device, when viewed as a character device (a.k.a. "raw" device, used for fsck) (leave this undefined, if your OS doesn't have raw devices)

For the truly high capacity formats (XDF, 2m, etc), there is no clean and documented interface yet.
