mtools

MTOOLS(1)						      General Commands Manual							 MTOOLS(1)

NAME

       Mtools - a collection of tools for manipulating MSDOS files

SYNOPSIS

       mattrib - change MSDOS file attribute flags
       mcd - change MSDOS directory
       mcopy - copy MSDOS files to/from Unix
       mdel - delete an MSDOS file
       mdir - display an MSDOS directory
       mformat - add an MSDOS filesystem to a low-level formatted diskette
       mlabel - make an MSDOS volume label
       mmd - make an MSDOS subdirectory
       mrd - remove an MSDOS subdirectory
       mread - low level read (copy) an MSDOS file to Unix
       mren - rename an existing MSDOS file
       mtype - display contents of an MSDOS file
       mwrite - low level write (copy) a Unix file to MSDOS

DESCRIPTION

       Mtools  is  a public domain collection of programs to allow Unix systems to read, write, and manipulate files on an MSDOS filesystem (typi-
       cally a diskette).  Each program attempts to emulate the MSDOS equivalent command as closely as practical.

       MSDOS filenames are optionally composed of a drive letter followed by a colon, a subdirectory, and a filename.  Subdirectory names can  use
       either the '/' or '' separator.  The use of the '' separator or wildcards will require the names to be enclosed in quotes to protect them
       from the shell.

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

       All options use the '-' (minus) flag, not '/' as you'd expect in MSDOS.

       The mcd command is used to establish the device and the current working directory (relative to the MSDOS filesystem), otherwise the default
       is assumed to be A:/.

SEE ALSO

       mattrib(1), mcd(1), mdel(1), mformat(1), mrd(1), mren(1), mtype(1), mcopy(1), mdir(1), mlabel(1), mmd(1), mread(1), mwrite(1)

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.
