Plait (pronounced "play") is a command-line jukebox and music player front-end. It understands brief queries that pick a single song, mix queries that combine works from multiple artists, and stream queries that find Shoutcast radio streams.
This command-line tool will help people who want to compare 2 csv-like files, and get a detailed report on which rows and fields differ between both files. An awk-based version and Perl Version is currently available.
