Episode 4: Removing Unneeded Files exercise needs rewrite #848

All valid points, but I think there are enough exercises in the loops section already, and this exercise is to practice wildcards rather than loops.
It would however be good if the exercise could be tried by learners rather than it being just a thought experiment.
I'm reluctant to create more files in the data-shell directory though, because this lesson is scattered enough as it is. Perhaps it could be made clearer that this is a thought experiment, with instructions on how to create some files with touch, in order to try out the commands?
