Return codes from remote commands

[Robert S. White]

This should be a simple problem.
I need to test for the existance of a file on a remote host. rsh test -f does not work because not matter what the result of the test command, rsh completes sucussfully ( ie returns 0 ).
I'm checking $?.
Any ideas would be helpful.

Hi Robert:

Write the result of the file test into a *file* that you fetch to retrieve to determine the success or failure.

How about this:

filespec=/path/to/file
RESULT=`remsh remotehost "ls $filespec" 2>&1`
if [ "$RESULT" = "$filespec" ]
then
#found the file ... do something
else
# nothing found ... do something else
fi

HTH. Good luck

Wow that was quick.
Kofi ARTHIABAH your solution is a gem.
I was thinking that I would need to do something like what JRF listed, but your solution is the simple one I needed!


Thank you!
