NAME
mcd - mtools utility to change or report the DOS working directory
SYNOPSIS
mcd [msdosdirectory]
DESCRIPTION
Without arguments, the mcd command reports the current device and working directory. Otherwise, the mcd command changes the current device
and current working directory relative to a DOS file system. Unlike the DOS command CD, the mcd command can be used to change to another
device.
The environment variable MCWD can be used to locate the file where the device and current working directory information is stored. The
default is $HOME/.mcwd. The file is created if it does not exist and a msdosdirectory is specified.
DOS pathnames that contain the '/' or '' separator are supported. If you use the '' separator or wildcards, you must enclose file names
in quotes to protect them from the shell.
The mcd command supports the use of to move back one directory in the tree, however, multiple relative moves such as are not supported and
do not affect your current position in the directory tree.
NOTES
At logout time, it is advisable to remove old files.
EXIT STATUS
The following exit values are returned: Success. Failure.
ENVIRONMENT VARIABLES

mtools working directory as established by the mcd command. If this variable is not set, the file $HOME/.mcwd is used.
