Shell Programming and Scripting

Hi,
a little help.

I need to test the return code of a list file command on a remote system (Unix) using the rsh command. More exactly, to test is a directory exists, I try the following command:

rsh $remoteHost "ls -la " $DirRemote

Now, if the $DirRemote is not correct and I test the $? I found 0.

If I try to check the $? on remote system for this remote command, in this way

rsh $remoteHost "ls -la " $DirRemote " ; echo $?"

to capture a value different, the value is always 0, preceded by an error message.

Any idea?
Thanks in advance.

I really don't know anything about the rsh command, but you could try PxT's idea.. no idea if it works or not since the OP never responded.

Here's another post, but I'm not sure how much help it'll be either.

Thanks a lot oombera!
My problem was the single quotes not used in my code!

Now I solved the problem in this way:

rsh $remoteHost 'ls -la $DirRemote >/dev/null 2>$1 ; echo $?'

and the return code is correctly set to 2.

Won' t you think using single quotes for the whole thing will be good

like

'rsh $remoteHost 'ls -la $DirRemote >/dev/null 2>$1 ; echo $?'

I think this will tell you if the rsh fails and your ls passes.
