Most of my shell work is encapsulated in a helper script, which is capable of doing things like querying our build server, looking at properties of pull requests, etc.

I'm often glad I wrote it to print out the command it's going to run before running it, because none of my coworkers want to use my helper script, but they've many times asked me to for some obscure command that I encapsulated in it and don't actually remember myself.
