so they didn't learn about fork/exec in that course? I don't believe it wasn't mentioned :)

OS class is not about Linux, its about OS theory. You learn the algorithms for priority queues and preempting tasks and even build a simple OS (depending on the class). Very little of it is about how IRL operating systems/kernels like NT or Linux work, though they did use some examples to demonstrate. Forking was more in Systems programming class, but that class was more about C, system calls, linking, and gdb. Not much time was dedicated to the syntax of shell scripts.

"forking" has absolutely nothing to do with "the syntax of shell scripts".

Proving my point more and more here…

Again, try to remain polite. I understand how forking works. Knowing how shebangs work is not something they teach directly. Forking is.

so you know about fork but not about exec. It's not impolite to point out you didn't know something.

It's impolite to get offended.

No, im referring to your original comment calling me a "typical noob". It was an immature comment which contributes nothing, and again I think youre capable of more maturity than that.

Obviously, this conversation is based on your misunderstanding of the original post and so I dont think its a worthwhile use of either of our time to enumerate the chapters and system calls from a college class. Knowing how processes are created in a generic operating system is not the same thing as knowing how shebangs work on unix-like systems. Again, OS class is about how to MAKE an operating system, not how to use one

That particular bit of trivia wasn't covered. Why should it have been?
