in reply to sleep?

You can either add a $|++ to unbuffer STDOUT, or you can use the somewhat more Perlish (IMHO)

while (sleep(1)) {
  print "I'm going back to sleep.\n";
}

Note that this does change the logic slightly, in that the script will sleep for one second before the first print.

    Then why not say -
    do {
  print "I'm going to sleep\n";
} while (sleep(1))

      Yes, but note that do{}while(); is not actually a loop. You can't use loop control mechanics like last and next. This is noted under Universal Blunders, page 529 in Camel 2:
      • Using loop control statements in do {} while. Although the braces in this control structure look suspiciously like part of a loop BLOCK, they aren't.
      This is also mentioned here.

        Yes, but this is a simple example and does not use any loop control statements. myocom stated in his reply that the while(sleep(1)) construct would sleep first before showing any output - the opposite of what the original author was trying to do in the sample code. In this case, the do {} while () is a perfectly acceptable WTDI.
