GNU parallel, to run commands on all cores, and for its filename pattern substitution.
For example: ls *.flac | parallel ffmpeg -i {} {.}.mp3 encodes a directory of FLAC files to MP3. parallel -a <(ls *.flac) -a <(ls *.mp3) --xapply copytags {1} {2} then copies each FLAC file’s metadata to the corresponding MP3 file (which ffmpeg already does, just to illustrate the --xapply option).
