Need Help??

Can I pipe the output of the system command to my own program and read it in line by line. That way getting the best of both?

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]
