Readin STDOUT of external program through a pipe
|
Can't Post

Hi,
I need to read a STDOUT of an external program in my perl script. The thing is that that program is running all the time and I need to react immediatelly after it outputs every line. What happens is that when the external program outputs a line, my script doesn't do anything because that line is somewhere buffered. I tried $|=1, but did not work.
This is the code:
#!/usr/bin/perl
open (IN,'monbro -N monitor_definition |' ) or die "Error";
$|=1;
while ($line = <IN>) {
print $line;
}
close IN;
I
the prob
