mren—Rename or move an existing MS-DOS file or subdirectory
mren [ -voOsSrRA ] sourcefile targetfile
mmove [ -voOsSrRA ] sourcefile [ sourcefiles… ] targetdirectory
mren renames an existing file on an MS-DOS filesystem.
mren will allow the following command-line option:
voOsSrRA Verbose mode. Display the new filename if the name supplied is invalid.
If the first syntax is used (only one sourcefile), and if the target name doesn’t contain any slashes or colons, the file (or subdirectory) will be renamed in the same directory, instead of being moved to the current mcd directory as would be the case with mmove. Unlike the MS-DOS version of REN, mren can be used to rename directories.
