You’ll never guess what I learned from https://www.uninformativ.de/blog/postings/2023-11-19/0/POSTING-en.html. I’ve never seen for i do in shell scripts. Turns out, that walks over all positional arguments. So I reckon my for i in "$@"; do can now be shorter from now on. Very interesting in that detailled explanation to see all the – at least to me – inconsistent handling of semicolons and line breaks.
