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.
