Hello all!
I doing something as follows to run an external script with timeout on it + catching it's STDOUT:
eval {
alarm($timeout);
pipe(READ,WRITE);
if ($pid = fork) {
$SIG{CHLD} = sub { 1 while (waitpid(-1, WNOHANG)) > 0};
close(WRITE);
}
else {
die "Cannot fork: $!" unless defined $pid;
open(STDOUT, ">&=WRITE") or die "Cannot redirect STDOUT: $!";
close(READ);
exec ("$extScript") or die "Cannot exec $extScript: $!";
}
while(<READ>) {
push(@output, $_); }
close(READ);
alarm(0);
}; ## End eval
if ($@) {
if ($@ =~ /Timeout/) {
print "Reached timeout\n";
} else {
alarm(0);
die;
}
} else {
print Dumper(\@output);
}
That's working fine.
The question is how can I get the exit status of the script if it was finished before reached timeout.
Thanks
