mcd

mcd(1) General Commands Manual mcd(1)

Name
mcd - change MSDOS directory

Note of warning
This manpage has been automatically generated from mtools's texinfo documentation, and may not be entirely accurate or complete. See the
end of this man page for details.

Description
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 file system.

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.
