emv is a tool for mass-renaming files with a text editor. It can perform two pass renaming, link creation, file list splitting, and link target editing. emv logs its actions as shell-script-style mv commands in case you want to undo them.

It's especially useful if you want to see all the files at once and want to think about their names while editing and changing whole groups of files.
