How to automate telnet session using Expect?

Question

I\'m trying to write an expect script to automate telnet. This is what I have so far.

#!/usr/bin/expect
# Test expect script to telnet.

spawn telnet 10.62.

You're sending the echo command without first expecting the prompt. Try:

# after sending the password
expect -re "> ?$"
send "echo HELLO WORLD\r"
expect eof
