I'm 24 hours in and I didn't even know there were acts lol, but I assume I'm also on act 1. I've pretty much only done side missions.

Good point. But then if both the script and the command have the same filename, it will be important to make sure the script has a higher precedence in the PATH. Adding it to the end of .bashrc should be enough I think.

You could write a shell script:

#!/usr/bin/env sh

export SOME_ENV_VAR=value

command

Then place it on your path, for example /usr/local/bin/command_with_env.

I avoided overriding the command itself and naming the script the same, because then I think it would try to invoke itself.
