I think many devs learn the trade with Windows and don't get exposure to these tools.

Plus, they require a bit of reading because they operate on a higher level of abstraction than loops and ifs. You get implicit loops, your fields get cut up automatically, and you can apply regexes simultaneously on all fields. So it's not obvious to the untrained eye.

But you get a lot of power and flexibility on the cli, which enable you to rapidly put together an ad hoc solution which can get the job done or at least serve as a baseline before you reach for the big guns.
