Several different ways, with different effects:

qx(command), `command`, system(command), open(command|)
open(|command), fork and exec the desired command... and I'm
sure there's others.

qx(command), `command`,

(those two are the same thing)

system(command), open(command|)
open(|command), fork and exec the desired command...

You can use exec() without fork() too, but the semantics of that
are not often desired.

and I'm

I'm not.

I think you got them all (apart from modules).

Well, there is .xs and other perl extensions. ;-)

I thought of mentioning modules, but I realized that those
could only call upon existing language features. Using modules
can certainly make for cleaner code, though!
