Yes, you can pipe the output of the system command to `[your]` own program. In `perldoc -f open`, see the paragraphs following If the filename begins with '\|' ... Anno	[reply] [d/l] [select]

as you are using qx() (which gets the full output anyway) maybe you can simply redirect the output of your external command to a file (using the system shell and process that later `my $cmd = "$ext_cmd > $my_output"; # using unixlike shell system($cmd) == 0 or die; #` [download] (ignore if your OS is not unixlike) what does happen if you manually send SIGALRM to that external process? (wrap it in a shell if the execution time is too short). cheers --stephan	[reply] [d/l]
