This certainly seems to work. Must get my head around what it is doing now. Thanks.

    Must get my head around what it is doing now.

    $SIG{ INT } = sub { ## State makes $last a closure; that is a variable that remember' +s its value ## between invocations of the subroutine state $last = 0; ## if the time now is greater than 2 seconds later than the last +time we saw a ^C if( ( time - $last ) > 2 ) { ## Overwrite the last time with the current time $last = time; ## And just return; ignoring this ^C return; } ## However, if it is less than 2 seconds; die. die 'Interupted by ^C^C'; };

    With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
    "Science is about questioning the status quo. Questioning authority".
    In the absence of evidence, opinion is indistinguishable from prejudice.
      Ah, that makes a lot of sense. "State" was new to me (not using 5.010 yet) so threw me a little. Cheers
