Help on expect


I am writing a script to connect to a remote host and run a command. I wanted to use expect for this. Here it is below:

#!/bin/bash
#!/usr/bin/expect
ssh -o StrictHostKeyChecking=no -l pin100 slc02gnh.us.oracle.com
expect "Password: "
send "pin100\n"



The above code is not working as it displays the "Password: " and waits for the password. It is not taking send.

What is wrong with above.

You don't need #!/bin/bash if you're running it with expect.
And you probably need to add spawn:
Code:
#!/usr/bin/expect
spawn ssh -o StrictHostKeyChecking=no -l pin100 slc02gnh.us.oracle.com
expect "Password: "
send "pin100\n"
Maybe also need to expect another acknowledgement reply and in the end interact with it
Code:
...
interact
Can't test here sorry.

I could able to resolve the issue. Here is the script now:

#!/usr/bin/expect -f
spawn ssh -o StrictHostKeyChecking=no -l aindraka slc02gnh.us.oracle.com
expect "Password: "
send "Gothika1\r"
expect eof

But now i wanted to extend the script in such a way that if wanted to run few system admin commands after logging into the remote server.
First i tried running running few basic commands but it is not successful. can somebody help how to proceed from here.

I wonder if you really should expect the prompt and not eof. I don't know the behavior of eof yet, but are you certain that you're really able to log-in through it?
