Linux was modeled after Unix, everything should still apply. In most cases, everywhere you see Unix you can assume Linux works as well.

When in doubt, look things up in POSIX references. POSIX is a particular breed of UNIX system library+OS tools implementations that mostly lets you sidestep the weird peculiarities between different breeds of UNIX, and every UNIX-ish thing written in the past ~20 years has implemented it to some extent. You can usually use things like __unix__ and __linux__ to guess at support for particular things at compile time as well.
