How to use Expect in a Bash script

Question

I am trying to write a script that pulls the latest version of my software from a Git repository and updates the configuration files. When pulling from the repository though

This is pretty much taken from the comments, with a few observations of my own. But nobody seems to want to provide a real answer to this, so here goes:

Your problem is you have an Expect script and you're treating it like a Bash script. Expect doesn't know what cd, cp, and git mean. Bash does. You want a Bash script that makes a call to Expect. For example:

#!/usr/bin/env bash

password="$1"
sourcedest="path/to/sourcedest"
cd $sourcedest

echo "Updating Source..."
expect <<- DONE
  set timeout -1

  spawn git pull -f origin master
  match_max 100000

  # Look for password prompt
  expect "*?assword:*"
  # Send password aka $password
  send -- "$password\r"
  # Send blank line (\r) to make sure we get back to the GUI
  send -- "\r"
  expect eof
DONE

git checkout -f master
cp Config/database.php.bak Config/database.php
cp webroot/index.php.bak webroot/index.php
cp webroot/js/config.js.bak webroot/js/config.js

However, as larsks pointed out in the comments, you might be better off using SSH keys. Then you could get rid of the expect call altogether.
