Bulk rename files in macOS

Due to the fact I rip my CDs so I can listen them on my Sony NW-A306 I often have to bulk rename files after ripping.

This is the way you can do it

#!/bin/bash

for f in *.flac;
do
  NEW_FILE=`echo "$f" | sed 's/OLD_TEXT/NEW_TEXT/'`
  mv "${f}" "${NEW_FILE}"
done

Yes, I know, there are one liners that can do it. I don’t care.
