The script will wait for you to close the editor. (For convenience, I suggest to ⌘-drag the folder from the Finder into the Terminal window.) In Terminal.app, cd to the directory which contains the files you wish to rename. Install DiffMerge and gem install batch_rename (see README.md for details). edit 2 - the original Windows software is called Oscar's Renamer: I'm specifically looking for software with the kind of UI I described. edit - to clarify: I'm aware of OSX's built-in bulk file renaming options in Finder, and software along the likes of NameChanger, Renamer, Automator, ABetterFinderRename, etc. Modified filenames were highlighted with a different background and applying changes to all files was a simple CMD+S. You could use the keyboard's arrows to move around the filenames without extra clicks or bulky interfaces.

With the files in this interface, you had your 'standard' find/replace tools (CMD+F), as well as the ability to use REGEX. Imagine a text editor (such as TextEdit, Sublime Text, etc.) open to a document that simply lists all filenames, with each filename on a new line. You would select the files you wish to work with, and their filenames would appear within what was essentially a huge textarea. Many years ago - when I was a Windows user - I had an application which made renaming files an amazingly simple experience.
