Practical Exercise
Build a small shift-swap-requests folder, create a few request files, back one up with cp, rename another with mv, then clean up an old draft with rm.
Real-Life Healthcare Example
A clinic coordinator manually manages shift-swap request text files each week. Before automating anything, they need to reliably create, back up, rename, and clean up these files from the command line without accidentally deleting a request that has not been processed yet.
