HELP!! running program to ssh


Hi--

Im running a simple script to login to a remote server thru SSH and run a command.

#! /bin/sh +x
ssh user@server -2Y -C "(cd /RMA/prod/files/g3/area11/logs; ls -ltr)"

The script works fine but the script returns to the original host after executing the command, I want the script to execute the command without exiting on the remote server so i can run another command.

This may sound easy but it got's me a headache and I'm feeling the answer is right under my nose!

Can somebody help me, I really appreciate it!

Thanks!

Here is another interesting possibility. Have your script do three things:

1) Make the ssh connection
2) Copy a file (another script) to the remote server
3) Execute the copied script

That way, you could make the script do whatever sequence of instructions you wanted. If you don't know what you want to do until you see some output, and still stay logged in, that is a little tougher.

It logs you out at script completion because staying logged in remotely with execution privileges is a security risk.

There are basically 3 options:

1. if you really don't know what the next cmd will be, then you have to do it (login) manually
2. if you can make an intelligent script that can determine which cmds to run (eg Perl), then either
2a. copy script over and run it (as suggested) each time OR
2b. copy script over once only and auto run it each time you login (like your current version).

Appreciate the help, but this doesn't solve the problem.
I needed the script to not exit the remote server after executing the commands. I needed to run a program at the background and I needed the command prompt available.

Any other bright ideas?
