in thread Match Ip Address on cmd line

thanks so much, does the trick. what does qq mean ?

Also, yes I know this isn't a code writing service, but I could not find an 'if m/...' example in a command line, plus I would have never come up with 2 |'s

    The things you ask about are partly about style choices.

    Equivalent:

    do_something() if <condition>; if (<condition>) { do_something(); }

    Equivalent:

    m[regex] m|regex| m/regex/ /regex/

    Equivalent:

    "string-with-expanded-$variables" qq[string-with-expanded-$variables] qq/string-with-expanded-$variables/
    Using qq// is common on command lines, since the shell itself may require quotes or double-quotes.

    Equivalent:

    'string-expanding-no-variables' q[string-expanding-no-variables] q/string-expanding-no-variables/
    All of this can be found in perldoc perlsyn and perldoc perlop.
