Also, do y’all call main() in the if block or do you just put the code you want to run in the if block?

    Unix shell scripts are one of the few holdouts.

    I don’t know if this applies to other shells, but bash will not only execute your script line-by-line, it will also read it line-by-line. Which means that you can modify the behavior of a running script by editing lines that have not yet been executed*. It’s absolutely bonkers, and I’m sure that it has caused more than one system failure, during upgrades.

    * For example, if you run the following script

    echo "hello"
sleep 5
echo "goodbye"

    and then edit the third line before the 5 second sleep has elapsed, then the modified line will be executed.
