Easy Regex based mass renaming

ls /some/directory | sed -rn -e 's/input_file_regex/mv -v & output_file_name/p' | sh
Allows for quick mass renaming, assuming the user has some familiarity with regular expressions. Basically, it replaces the original_file_name in the output of ls with "mv -v original_file_name new_file_name" and passes the output to sh.
Sample Output
$ ls ~/manga/ | sed -rn -e 's/naruto_(...\.zip)/mv -v & \1/p' | sh
`naruto_431.zip' -> `431.zip'
`naruto_432.zip' -> `432.zip'
`naruto_433.zip' -> `433.zip'
`naruto_434.zip' -> `434.zip'

@unixmonkey2748: This 'rename' you are using is not portable and not present in most of the OSes. And the 'rename' you are using is not the 'rename' in util-linux-ng.

@jxy if you have Perl installed, you have 'rename'.

On my ubuntu system, rename is a symlink to prename, a perl script which uses (surprise) perl regular expression to do renaming. The util-linux rename command should still be available to invoke as 'rename.ul' Likewise, 'man rename.ul' will bring up the manpage for the util-linux rename.
