NAME
mmd - mtools utility to make a DOS directory SYNOPSIS
mmd [-v] msdosdirectory [msdosdirectories...] OPTIONS
Displays the new directory name if the name supplied is invalid. DESCRIPTION
The mmd command makes a new directory on a DOS file system. Unlike DOS conventions, this command accepts multiple arguments. Reasonable care is taken to create a valid DOS directory name. If an invalid name is specified, the mmd command changes the directory name and dis- plays the new name if the -v option is specified. If the directory specified exists, an error occurs. DOS subdirectory names are supported with either the '/' or '' separator. The use of the '' separator or wildcards will require the directory name to be enclosed in quotes to protect it from the shell. The mcd command can be used to establish the device and the current working directory (relative to DOS), otherwise the default is A:. EXIT STATUS
The following exit values are returned: Success. Failure. ENVIRONMENT VARIABLES
The following environment variables affect the execution of mmd: If set, this variable names the file that contains the name of the current mtools working directory as established by the mcd command. If this variable is not set, the file $HOME/.mcwd is used. FILES
