You don't want to background all thousands of processes as it will drag your processor to its knees. However, if your conversion program doesn't support multiple cores internally, and you have $CORES available, I'd recommend something like find /path/to/mp3s -type f -iname '*.mp3' -print0 | xargs -0 -n 1 -P $CORES my_conversion_program --my-conversion-options which will recursively find all *.mp3 files in /path/to/mp3s and launch "my_conversion_program" with "--my-conversion-options" and the filename to convert (it will do one at a time thanks to the "-n 1", but will spawn "$CORES" proesses). If you don't want to recurse into subdirectories, find(1) has options to control the max-depth as well. Instead of using $CORES, you might want to use $CORES-1 so that one is still free for you as a user of the computer. Hope this helps speed up jobs for you. -tim _______________________________________________ Blinux-list mailing list Blinux-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/blinux-list
