Expect

Automate the terminal. E.g.

#!/bin/bash
echo "Hello, who are you?"
read $REPLY
echo "Can I ask you some questions?"
read $REPLY
echo "What is your favorite topic?"
read $REPLY

#!/usr/bin/expect -f
set timeout -1
spawn ./questions
expect "Hello, who are you?\r"
send -- "Im Adam\r"
expect "Can I ask you some questions?\r"
send -- "Sure\r"
expect "What is your favorite topic?\r"
send -- "Technology\r"
expect eof

The second can be called directly.

Important comands for expect are:

1. spawn Starts a script or a program.
2. expect Waits for program output.
3. send Sends a reply to your program.
4. interact Allows you to interact with your program.
