need script to invoke on remote machine

Hi,
I need a script to invoke some command in remote machine.
For example,
our script should run in machine A. This script will connect to the remote machine B and invoke some commands there. Let's assume that the login id and passwd for machine B is uB and pB.

With Thanks,
Barun

There are several ways of doing this, the most common is by using SSH with key authentication (no passwords).

For example, this example will print the date from the remote computer, and return you to your normal (local) prompt:

Code:

$ ssh remote.server "date"
Fri May 15 07:38:36 PDT 2009
$

If you need to capture the output, you may need to wrap the above within another script, or take a look at the `expect` scripting 'language' which can wait for remote output (e.g. password prompts) and supply data when asked.

How can I authenticate the key using this ssh ?

can I also do this using ssh -s option ?
