A few years ago, I discovered this same flaw in using UNIX (Linux) well with some of the new hires (from really good schools, too), and it was worse because they often had never seen the true Bourne shell (nor knew much/anything about Algol, much less A68).  Many thought "bash" was the UNIX shell because they never knew better (chuckle).   I realized it was a huge hole in their education, so I got my admin to order each copies of K&R2 and UPE for their desks.   I said I expected them to do the exercises in them as part of their "training." I could usually tell a lot about each person by the questions they asked during that period. Many often griped about having to learn to use ed and nroff.  I think those that were already EMACS folks thought I was a little bonkers but my comment was that you'll understand the other tools better/be a lot more effective with the shell in particular. Many had seen Latex, so the >>idea<< of a document compiler was not always completely foreign.  But they crawled through each book.

But it was interesting when it was done. To a person, they all said they were much better with the UNIX tool kit after UPE, and because they actually read K&R2, they often learned a few things about C they never realized.  Once they "graduated" also I gave them a copy of APUE, if they were doing networking stuff, UNP too.  Most would start doing the APUE and UNP problems also as I would get some of them coming to my office with questions, but I never said they had to do them.
