2019-11-19 converting a bunch of files in a few lines

You may have a bunch of files that you want to convert from one format to another: images, videos, music, text, ... How do you convert them while using ZSH as your shell language in a single line?

I will take the example of music files which I wish totransform from FLAC to OPUS.

listing files

$ f flac

converting files

Encoding in 128kB/s :

$ f flac -exec  sh -c 'opusenc --bitrate 128 "$0" "${0%.flac}.opus"' {} \;

Note that this will work also while exploring the folder hierarchy (that is if you have a bunch of folders with those files).

deleting files

$ f flac -delete
