The other answers are great. But consider the following, as well.

All the mainstream package managers rely on POSIX-ish shell interpreters. Arch Linux PKGBUILD files require bash syntax, specifically.

RPM and .deb package formats literally embed shell scripts to perform pre- and post-installation tasks. They treat these scripts like hooks.

For instance, a common task would be to create requires users and directories for a program. Quite literally something like mkdir -p /var/lib/myprogram.

I’m an experienced dev who programs for a living, but I am kind of into this YouTube channel that (seems to) have a focus on beginners and career-switchers
