Is using expect and funneling your commands through an Expect script an option? <br><br>--j<br><br><div class="gmail_quote">On Thu, Apr 9, 2009 at 12:56 PM, Jeff Lightner <span dir="ltr"><<a href="mailto:jlightner@water.com">jlightner@water.com</a>></span> wrote:<br>

the local host rather than the remote one so results in:<br>
<br>
ls: /felix/preprod/jboss/server/default/log/log/webserver.log*: No such<br>
file or directory<br>
<br>
As I said I've tried various quoting, escaping, eval methods. The issue<br>
is they all make it either pass the variable (not its value) to the<br>
other side so it doesn't know the value or they evaluate parts of the<br>
command locally where they have no relevance.<br>
<br>
It just seems really odd to me that ssh doesn't have something built in<br>
that would allow it to process a locally defined variable on the remote<br>
side. I see many have asked the question but didn't see any obvious<br>
solution.<br>

Hmmm. Problem is, your variable is inside a single-quoted string, so it<br>
isn't getting expanded on the local host. Is there a specific reason<br>
you're not just saying<br>
<br>
ssh $REMSERVER "ls -tr ${REMLOGDIR}/webserver.log* |xargs grep<br>
-hA 10 DEBUG"<br>
<br>
?<br>
