in reply to First obfuscation attempt

Doesn't work for me on Win XP. I get
Can't find string terminator "'" anywhere before EOF at -e line 1.

A simple fix to the system call fixed the problem.
#!/usr/bin/perl @m=qw/13 12 108 105 101 78/;$c=join("",map(chr,qw/112 114 105 110 116 32/));1 && $c .="map chr,reverse qw/@m/";1&& system "perl -e \"$c\"";
