rename [options] expression replacement file...
rename will rename the specified files by replacing the first occurrence
of expression in their name by replacement.
Do not rename a symlink but its target.
Show which files were renamed, if any.
Do not make any changes; add --verbose to see what
would be made.
Do not overwrite existing files. When --symlink is
active, do not overwrite symlinks pointing to existing targets.
Ask before overwriting existing files.
Display version information and exit.
Display help text and exit.
The renaming has no safeguards by default or without any one of the options
--no-overwrite, --interactive or --no-act. 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.
As most standard utilities rename can be used with a terminal device (tty in
short) in canonical mode, where the line is buffered by the tty and you press
ENTER to validate the user input. If you put your tty in cbreak mode however,
rename requires only a single key press to answer the prompt. To set cbreak
mode, run for example:
sh -c 'stty -icanon min 1; "$0" "$@"; stty icanon' rename -i from to files

Given the files foo1, ..., foo9, foo10, ..., foo278,
rename foo foo00 foo?
rename foo foo0 foo??
will turn them into foo001, ..., foo009,
foo010, ..., foo278. And
will fix the extension of your html files. Provide an empty string
rename '_with_long_name' '' file_with_long_name.*
will remove the substring in the filenames.
