Fair. My bash scripts only broke 3 times over the years:

- when ls started quoting filenames with spaces (add -N)

- when perl stopped being installed by default in CentOS and AlmaLinux (had to add dnf install -y perl)

- when egrep alias disappeared (use grep -E)

Bash is not a great cross-platform choice. Too many subtle differences.

The best way is a scripting language with locked-down dependency spec inside the script. Weirdly .NET is leading the way here.

For some quality of "run", because I'm hella sure that it has quite a few serious bugs no matter what, starting from escapes or just a folder being empty/having files unlike when it was written, causing it to break in a completely unintelligible way.
