Dealing with macOS output in a fast manner using `string` is surprisingly hard, given that it features lines like
gls(1), ls(1) - list directory contents
Printing the "gls" with the description and the "ls" with the description requires a `while read` loop, and that's too slow.
This reverts commit 7784a5f23c.
