Forget this mess!<br><br>Better mess!<br><br>I need to capture the PID of a process started over rsh (no hollering about using ssh - cluster of compute nodes behind a master node). The process is started on the master node with a heavily scripted rsh call.<br>
<br>Some stuff I've tried: <br>rsh $node 'echo $$; $command < $input &'<br>rsh $node 'echo $$; $command < $input &' &<br>rsh -n $node 'echo $$; $command < $input &'<br>
mypid=$(rsh $node 'echo $$; $command < $input &')<br>rsh $node 'echo $$; $command < $input &' 2>&1<br><br>Yes. The echo $$ will actually get me the pid of the remote login shell but that's enough<br>
<br>BTW: RHEL5 has a BUSTED rsh. -n DOES NOT WORK!<br><br><div class="gmail_quote">On Thu, May 12, 2011 at 2:10 PM, Jim Kinney <span dir="ltr"><<a href="mailto:jim.kinney@gmail.com">jim.kinney@gmail.com</a>></span> wrote:<br>
