Hi,

Why the following never becomes true ?

if ($name =~ /$key/) {

Values:

$name="Intel[R] PRO_1000 MT Network Connection _2 - Packet Scheduler Miniport"
$key="Intel[R] PRO_1000 MT Network Connection _2"

thanks

Yes,
The \Q tells Regex engine to treat the special characters ([ and ] in this case) as regular characters and \E tells to stop treating it.

So [ and ] are treated as regualr charactes instead of character class declaration in regex.
