Create a shell script (named "do-ipod-compress", for instance) that runs your ffmpeg command: (the below code should be close. No guarantees, though...I haven't actually tested it. Also, the below method will just tack on the .mp4 extension. If you want to replace the .mpg extension, you'll need to do a bit more munging) #!/bin/bash ffmpeg -i $1 $1.mp4 Then from cron (or manually), you can run: find /path/to/files -mtime 24 -type f -name "*.mpg" | xargs do-ipod-compress That will list all .mpg files in the path that have been modified (or created) in the past 24 hours, and will pass each list item in turn to the compress script.
