mren(1)


NAME

  mren - mtools utility to rename an existing DOS file


SYNOPSIS

  mren [-v] sourcefile targetfile


OPTIONS

  -v  Specifies verbose mode.  The new file name is displayed if the name
      supplied is invalid.


DESCRIPTION

  The mren command renames an existing file on a DOS file system.  You can
  also use the mren command to rename directories.  Reasonable care is taken
  to create a valid DOS file name.  If an invalid DOS targetname is
  specified, the mren command changes the name and, if the -v option is
  specified, prompts the user to accept or reject the new name.

  The path component of the targetfile argument, if supplied, is ignored.
  That is, you cannot use the mren command to move a file from one
  subdirectory to another.

  DOS subdirectory names 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 can be used to establish the device and the current working
  directory (relative to DOS), otherwise the default is A:\.

  Not all UNIX file names are supported in the DOS world.  The mren command
  may have to change UNIX names to fit the DOS file name conventions. The
  following table shows some examples of file name conversions:

  ______________________________________________
  UNIX name	DOS name   Reason for the change
  ______________________________________________
  thisisatest	THISISAT   file name too long
  file.stuff	FILE.STU   extension too long
  prn.txt	XRN.TXT	   PRN is a device name
  .abc		X.ABC	   null file name
  hot+cold	HOTXCOLD   illegal character
  ______________________________________________


RESTRICTIONS

  You cannot use the mren command to move a file from one subdirectory to
  another.


EXIT STATUS

  The following exit values are returned:

  0   Success.

  1   Failure.


ENVIRONMENT VARIABLES

  The following environment variables affect the execution of mren:

  MCWD
      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

  $HOME/.mcwd
      Contains the name of the current mtools working directory as
      established by the mcd command.  If this file does not exist, the
      default mtools working directory is A:\.

  /usr/bin/mtools/mren
      Executable file
