Probably means there will be new PNGs that old software won’t be able to open.

Exactly. There need to be rules that make people responsible for decisions made by software.

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).

edit: copytags is https://github.com/DarwinAwardWinner/copytags if that’s useful for anyone.
