I wrote previously about ffmpeg and audio variable bitrate. After conversion, there are some files that did not convert. I would like to compare two listings and discover which ones are missing. So, we have these commands: find . -type f -name \*.m4a | sed -e 's@.*/@@' -e 's/\.4a$//' > m4a.txt find raw2 -type f -name \*.mp3 | sed -e 's@.*/@@' -e 's/\.mp3$//' > mp3.txt Now I want to run comm and have it dump to another file which lines in m4a.txt do not exist in mp3.txt. How would I go about doing that? Or is there a better way? _______________________________________________ Blinux-list mailing list Blinux-list@xxxxxxxxxx https://listman.redhat.com/mailman/listinfo/blinux-list
