mren(1)
NAME
  mren - mtools utility to rename an existing DOS file

SYNOPSIS
  mren [-v] sourcefile targetfile

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

DESCRIPTION
  The mren command renames an existing file on a DOS filesystem.  You can
  also use the mren command to rename directories.  Reasonable care is taken
  to create a valid DOS filename.  If an invalid DOS targetname is specified,
  the mren command changes the name and, if the -v flag 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 filenames 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 filenames are supported in the DOS world.  The mren command
  may have to change UNIX names to fit the DOS filename conventions.  The
  following table shows some examples of filename conversions:

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