MANY THANKS!

Perhaps you guys can solve the other part of the equation. Right now I'm doing something like this:

 #===== Open I/O pipes and run the process
  $pid = open3(\*DEV_NULL, \*OUT, \*ERR, "my_long_process");
  
  #===== Print the results
  while (<OUT>)
  {
    $buffer .= $_;
  
    #===== Update the display cache
    $cache->set($session, [0, $buffer]);
  }
[download]

Which works, except it waits until my_long_process completes before it sends any output back to the browser. If my_long_process takes an hour to run, the browser sits there for an hour with no updated information.

Is there a way to set open3() to an unbuffered mode so it returns what my_long_process is doing in real time?

Failing that, is there a better way to do this long process in the fork such that I can get its results as its doing things rather than waiting until the end?

Thanks!
