This is a use at your own risk bash script I wrote to grab the artist and title from an mp3’s id3 tags using exiftool. The script prompts the user to decide it they want to keep the old file name or rename it with the format:
I’ve written a lot of shell scripts but never posted one for others to use so, users, ye be warned!
Be sure to leave a comment it you try it out, I’d love to get some feedback on this. Thanks.
Here’s a listing of my script:
#!/bin/bash
# id3_convert.sh — Written by Christian Benedict — 11/27/2010
# Dependencies — exiftool, .mp3 files only at this time
# Check if $1 begins with “-” than translate it as a parameter. -f file mode (default), -d directory mode, -n no prompt to skip empty id3 files, –help
# I may add ability to edit id3 artist and title in the future.
