The `which` command identifies the location of a command. It does this by searching the `PATH` for executable files. The `-a` option prints all matching locations. To inspect the `PATH`, use `tr` to split it into separate lines for improved readability.
I prefer `!/bin/sh` over `!/bin/bash`. I begin almost every script with the same four lines. Use a POSIX-compliant shell. Exit immediately if any command returns a non-zero status (indicating an error).
