Question

I’m trying to use expect to talk to a bash script, but I’m missing something. My script is:

#!/bin/bash
echo -n "foo? "
read
echo $REPLY

and my expect script is:

#!/usr/bin/expect
spawn ./script.sh
expect "foo? "
send "bar\r\n"

But I never see bar when I run the expect script. What am I missing here?

Answer 1

Dumb me, I needed to add interact to my expect script so that it can finish “interacting” with the script:

#!/usr/bin/expect
spawn ./script.sh
expect "foo? "
send "bar\r\n"
interact

I found the answer here two minutes after asking this question.
