hi!

well, i wanna have a "status-bar" via forking - while the
parent should display the status-bar (a 1char, changing sign),
the child should do the actual job. well the child does fine,
but the parent doesn't - here's the source i used so far:

if ($pid = fork)
 {
  # parent
  do
   {
     print "\b-";  sleep 1;
     print "\b\\"; sleep 1;
     print "\b|";  sleep 1;
     print "\b/";  sleep 1;
     $child_pid = waitpid(-1,0);
   } until $child_pid == -1;
 }
else
 {
  # child
  exec("cmd");
  exit(0);
 }
waitpid($pid, 0);
well, the "do"-loop doesn't actually loop - how can i get it
looping, until the child has done its job ?
thnx for any hint/snippet... - nostromo
