Any decent school will teach UNIX as it's still a very large part of our computer infrastructure, unless all you plan to do upon graduation is fix home computers and play help desk in a company. As I said, my school had dual Linux/Windows systems in the labs for teaching both.
If our schools are giving veterinarian or soil hydraulics engineering students coerces in UNIX programing that would explain a lot of why our educational system is screwed up.
Interesting you mention engineering, since UNIX is still extremely popular in that field.
