|> Windows is clearly superior to Linux,
You mean because on Windows you need to put the code in double quotes which don't collide with single quotes?
The best thing would be a Perl shell without the need to quote at all and calling OS commands inside out.
the second best thing is perl <RET>
Perl reads from STDIN then, Ctrl-d or __END__ ends it. Works on both plattforms.
Name "main::x" used only once: possible typo at - line 2.
Use of uninitialized value $x in print at - line 1.

Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
Read Where should I post X? if you're not absolutely sure you're posting in the right place.
