Top Forums Shell Programming and Scripting Switch user without password inside shell Post 302911494 by Don Cragun on Friday 1st of August 2014 03:01:51 AM

Steps to be executed by ssh that come from the script (rather than from the script's standard input) need to be redirected:
Code:
#!/bin/ksh 
ssh user1@host1 -P password <<-EOF
        sleep 1 
        ping host3
        # other commands to be executed through ssh
EOF
# other commands to be executed after ssh session terminates.

Note that using -P password this way makes user1's password on host1 visible to anyone who runs ps while ssh is running. Consider putting the password in the here-document; then that user's password is only public to anyone with permission to read your script. Depending on your security requirements, you may want to explore other ways to enter the password.
