in reply to sleep in while loop

What do you mean by "it just hangs"? 
    while (1) {
        ... do something ...;
        sleep 10
    }

isn't going to terminate, unless you exit the loop from the do something part.

    I don't want it to exit from the loop, when I say it just hangs I mean it doesn't execute any other code, it just seems to go straight to the sleep function and stay there. I want the prog to loop indefinitely until it is killed by the user. i.e: while (1) { if($cond = 1){ print "1"; } else{ print "2"; } sleep 10 } it doesn't do the conditional statements (just eg's) or any other statements in the prog, it just hangs on the cmd line: ./prog.pl Huh ?

      You may be getting bitten by buffering. Try this: 
      $|++; # force auto-flush (see perldoc perlvar)

while (1) {
  if ($cond == 1) {
    print "1\n";
  } else {
    print "2\n";
  }
  sleep 10;
}

        Thanks - buffering was biting my proverbial ***- by the way the code in the loop was not the actual code - sorry to confuse the issue.
