RE: [Condor-users] Possible Limitation Condor vs Perl / IPC::open3

["Dave Lajoie" <dlajoie@xxxxxxxxxxxxxxxxxxxx>]

Correction
	the perl script below is incorrect (uses ping as the process)
	the script should look like this instead	

$cmd = 'ping -n 10 localhost |';
$pid = open(XSIPROC,$cmd) or die "Cannot run $cmd: + $!";

while(<XSIPROC>)
{
	print $_;
}

I get the following error when submitting the file
Cannot run ping -n 10 localhost |: + Bad file descriptor at
C:\Condor\wrapper\test.pl line 2.

If I run it thru command line, it works.

C:\>perl c:\Condor\wrapper\test.pl
