Permit me to vent just a bit:

> Python is a great scripting language, and won't blow your foot off if you try to iterate through an array.

I kind of hate that every time the topic of shell scripting comes up, we get a troop of comments touting this mindless nonsense. Python has footguns, too. Heck, it's absolutely terrible and hacky if you try to do concatenative programming with it. Does that mean it should never be used?

Instead of bashing the language, why not learn bash the language? IME, most of the industry has just absorbed shell programming haphazardly through osmosis, and almost always tries to shove the square pegs of OOP and FP into the round hole that is bash. No wonder people are having a bad time.

In contrast, a data-first design that heavily normalizes data into line-oriented tables and passes information around in pipes results in simple, direct code IME. Stop trying to use arrays and embrace data normalization and text. Also, a lot of pain comes from simply not learning the facilities, e.g. the set builtin obviates most uses of string munging and exec:

    set -- "$@" --file 'filename with spaces.pdf'
    set -- "$@" 'data|blob with "dangerous" characters'
    set -- "$@" "$etc"
    some_command "$@"

Anyway, the senseless bash hate is somewhat of a pet peeve of mine. Exunt.
