Shell Programming and Scripting

I have a script that will ssh to several different servers, perform a command, display the output, and exit. It works well, but I have to enter my password for each server. That gets a little cumbersome when you have a couple dozen servers. Anyone out there know how to automate this so that I only have to enter my password once? Here's the script like what I'm currently using...

Code:

#!/usr/bin/env  ksh -p
  
 getLogin()
  { 

    stty  -echo
    read  pwd?'Please enter your production password: '
    stty  echo
     echo
  
    return  0
 }
  
 getLogin
 ssh  user@server1 'ls  /path/resubmit'
 ssh  user@server2 'ls  /path/resubmit'
 ssh  user@server3 'ls  /path/resubmit'
 ssh  user@server4 'ls  /path/resubmit'

Use ssh-agent, or set up keys with empty passwords.

You could use cssh to do that (SourceForge.net: cssh). Very useful for doing work on many servers at once.
Otherwise I'd do as era suggests.

As a final option, you could use 'expect' to send the password to ssh each time (that's kind of ugly though)
