Replace in Filenames (Regex)

Summary: Lets you make changes to the filenames of the selected records using find and replace and regular expressions.
Requires: EagleFiler
Install Location: ~/Library/Scripts/Applications/EagleFiler/
Last Modified: 2011-11-09


EagleFiler will replace the source pattern with the replacement template in the filename of each selected record. This script deals with Unix filenames, so for a “/” character as shown in EagleFiler enter “:”, and for a “:” character enter “/”.

Regular expression patterns follow the Python syntax. The replacement template can use numeric backreferences (“\1”, “\2”) and named backreferences (“\g<1>”, “\g”).
