rename - rename files
rename [options] expression replacement file...
rename will rename the specified files by replacing the first occurrence of expression in their name by replacement.
-s, --symlink Do not rename a symlink but its target. -v, --verbose Show which files where renamed, if any. -V, --version Display version information and exit. -h, --help Display help text and exit.
Given the files foo1, ..., foo9, foo10, ..., foo278, the commands rename foo foo0 foo? rename foo foo0 foo?? will turn them into foo001, ..., foo009, foo010, ..., foo278. And rename .htm .html *.htm will fix the extension of your html files.
The renaming has no safeguards. If the user has permission to rewrite file names, the command will perform the action without any questions. For example, the result can be quite drastic when the command is run as root in the /lib directory. Always make a backup before running the command, unless you truly know what you are doing.
