There's a lot of different comparisons that can be done with perl.

Operators:
$1 == $2 : If variable $1 is the same as variable $2, carry on.
$1 != $2 : If variable $1 is NOT the same as variable $2, carry on.
$1 > $2 : If variable $1 is greater than variable $2, carry on.
$1 < $2 : If variable $1 is less than variable $2, carry on.
$1 >= $2 : If variable $1 is greater than or equal to variable $2, carry on.
$1 <= $2 : If variable $1 is less than or equal to variable $2, carry on.
$1 eq $2 : If string variable $1 is the same as string variable $2, carry on.
$1 ne $2 : If string variable $1 is NOT the same as string variable $2, carry on.
$1 =~ $2 : If string variable $1 contains/matches the string variable $2, carry on.

Yours is the last on the list. It makes text-based chat with NPCs a little more forgiving.
