I'll add that I still think parent comment has some right to be perplexed. While it's true that these things aren't part of a CS curriculum you'd normally expect a CS student to be curious about these things and able to pick them up quickly. It's okay to be a bit surprised if they haven't, I think?
I think the world has shifted significantly, it might have been the case to expect that people would learn things like the Unix shell or git on their own when CS was a major for nerds, but realistically these days many people sign up for CS without neither the passion for hacking nor the math chops. It's just a major like any other to them, and they are basically in for the money. Obviously any personal choice is fine, but we should adjust our priors accordingly.
> you'd normally expect a CS student to be curious about these things
Let me quote a uni mate of mine that stayed in teaching at said uni when we finished:
"When we were studying CS there were X students in a year. X/5 were passioned and very good, 4X/5 were passioned and good and the rest of X/5 were doing ok."
[After our 10 year reunion, when IT is suddenly a high paying job and all you need is to be able to write some ifs to get hired.]
"Now there are 3X students in a year. X/5 are passioned and very good, 4X/5 are passioned and good, another X/5 are doing ok, and I have no idea why the rest of 2X are here."
