Shell scripts were a mistake. The weirdness you have to remember to safely stop executing when something fails is mind-boggling.
I'm so glad nushell exists and doesn't need any configuring to just do the reasonable thing and stop executing when something fails.
All you need to do is
set -eat the start of the script to stop on a non-0 exit code. And quote variables to prevent globbing.Oh you sweet summer child.
If you don't use pipes or command substitutions,
set -egets you a fair part of the way there.If you're interested, I can look up the rest of the arcane incantations necessary.
