Well... since you didn't bother to limit it to only "simple user tasks".....
for i in * do mv $i `echo $i | tr [:upper:] [:lower:]` done
Done, all the files in that directory are now lower case.
And that's just it. It's another case of "See how easy that was? Oh, we just need to add some quotes. Oh, and -- as an argument for mv. Oh, and -i as an argument for mv.

Once again, my image is just a screenshot from a photo taken non-orthogonally at a painting.
TinEye is also extremely useful to help understand a photoshop meme

Isn't that pretty much like saying: "Actual Windows developers don't seem to share your concern. As I've said before, only Linux fanboys seem to care about Windows' supposed security issues."?
(replace with your favourite OS/kernel/whatnot)
Maybe the developers should care?
