At least the behaviour on Linux (or any unix) is expected: if you pass
a list to perl's system(), perl does not run the command under a shell
(a shell is only invoked if there's only a scalar argument to system()
(or if the list has only one element) and that argument contains shell
metacharacters). That's a source of no small amount "fun" for perl
programms "shelling out", because "sometimes" there is no shell.
Perl's system hase some more caveats, "perldoc -f system" has a
starter on that topic.
