Bulk Rename Files

Rename Multiple Files of the Same Name but Different Extension

for i in old_name.*; do mv "$i" "new_name.${i##*.}"; done

The Drupal module "mymodule" has multiple files with the name "mymodule" but differing extensions.

ls -1
mymodule.css
mymodule.inc
mymodule.info
mymodule.js
mymodule.module

We want to rename all of these files to "yourmodule" while keeping the various extensions intact.

for i in mymodule.*; do mv "$i" "yourmodule.${i##*.}"; done

ls -1
yourmodule.css
yourmodule.inc
yourmodule.info
yourmodule.js
