## Description
TODO: Fill out (required)
As a [user or stakeholder], I want [goal or objective] so that [reason or benefit].
----
Lets review all of our shell scripts for the ~"Category:Remote Development" across all repos, and ensure they are as safe and clean as possible.
We should also establish linting standards to ensure they stay this way (can be follow-up issue).
