Given the files foo1, ..., foo9, foo10, ..., foo278, the commands
rename foo foo00 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. Provide an empty string for
rename '_with_long_name' '' file_with_long_name.*
will remove the substring in the filenames.
The renaming has no safeguards except the --no-act option. 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.
