I don't see a problem with your first example:
$Line = "Hey there look it works";
if ($Line =~ /@ARGV[2]/i){
print "True\n";
}
if the script is called pl.pl then the following happens:
$ pl.pl arg0 arg1 THERE
True
$ pl.pl arg0 arg1 crap
but if @ARGV[2] is nothing (ie "") then // will use the last successful
pattern match to try again, or else it will always be true if there was no
previous pattern match.
Show us more code or the error if any.
