> How on earth would a uni student in CS don't know about piping commands?

Beyond the obvious ones, lots and lots of valid reasons this could happen:

1. Student is entirely new to programming as a concept and just started in university. Not every fresh CS student has been programming since birth.

2. Student uses the shell entirely for basic commands and honestly doesn't even realize it can be used for more advanced things

3. Student is really interested in the "Science" part of CS and isn't planning on being a developer. Plenty of brilliant CS minds are awful at the programming part but extremely adept at, say, consensus protocols.

Your basic first year CS curriculum might offer a crash course in things like basic shell scripting, but it's certainly not a given. Computer Science is a very broad field and it's arguably a huge waste of time for them to teach you how to pipe commands when they could be teaching you something you can't pick up in 10 minutes, like automata theory.
