She didn't need to know IRIX if she knew some other flavor of Unix, she was probably savvy enough to use man and access documentation if needed.
The point is though most mock the scene as though the software they show was entirely fictional and made up, when it was in fact real and was in fact still UNIX.
I don't know why others mock it, but as an older person working in IT, I can explain why I mock it even when knowing it was real software SGI shipped with IRIX.
Yeah that's pretty bad. I don't know what I'd say the worst movie scene was, most of my bad examples come from TV. That CSI visual basic example is pretty infamous.
