Given the files
foo1, ..., foo9, foo10, ..., foo278,
rename foo foo00 foo?
rename foo foo0 foo??
will turn them into
foo001, ..., foo009, foo010, ..., foo278.
rename .htm .html *.htm
will fix the extension of your html files.
Provide an empty string for shortening:
rename '_with_long_name' '' file_with_long_name.*
will remove the substring in the filenames.
The renaming has no safeguards except the
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.
