( #3333=superdoc: print w/ replies, xml ) Need Help??

Well blow me down, BrowserUK is correct. I've never gotten alarm() to work reliably on Windows - perhaps because I'm not that versed in Signals and didn't know what I was doing or was trying on a system call without the eval/die as described in alarm; however, alarm() added in my original script works:

use strict; use warnings; my $pid = open(my $fileHandler, '-|', "./test.exe" ); my $DONE = 0; $SIG{ALRM} = sub { $DONE = 1 }; alarm 2; while (<$fileHandler>) { print "$_\r"; # \r to not overrun output screen buffer last if ($DONE) } print "\nTimeout! - Time to kill pid: $pid\n"

And the output

VinsWorldcom@C:\Users\VinsWorldcom\tmp> TimeThis test.pl TimeThis : Command Line : test.pl TimeThis : Start Time : Fri Oct 12 13:01:09 2012 114601 Timeout! - Time to kill pid: 4700 TimeThis : Command Line : test.pl TimeThis : Start Time : Fri Oct 12 13:01:09 2012 TimeThis : End Time : Fri Oct 12 13:01:12 2012 TimeThis : Elapsed Time : 00:00:02.454
