running command with expect

Question

I have created a shell script which will automate login to a remote machine.
But I need to automate the execution of commands or shell scripts also along with this script.
What modification do I need to do with shell script for creating a directory(for example!) in the remote machine ?

#!/usr/bin/expect
set login "root"
set addr "10.3.2.0"
set pw "root"

spawn ssh -t $login@$addr
expect "$login@$addr's password:"
send "$pw\r"
interact

Thanks in advance.

You might want to find an Expect tutorial or read the "Exploring Expect" book. — glenn jackman

You can simply add statements to your script:

#!/usr/bin/expect
set login "root"
set addr "10.3.2.0"
set pw "root"

spawn ssh -t $login@$addr
expect "$login@$addr\'s password:"
send "$pw\r"
expect "~" ; # put here string from your server prompt
send "mkdir some_dir\r"
interact

Can you be more concrete? What error did you get? Have you changed the expect statement to your server prompt?

Its worked !!.I thought it didnt work since it diplayed mkdir some_dir in shell.But the directory was created !

or if you do not have info about the prompt how will look like commands with spawn can be invoked one by one separated with interact:

spawn command1
interact
spawn command2
interact
spawn command3
interact
