title: echo -e working in terminal but not in bash script
body: <p>I developed and maintain a ruby gem called Githug and I am trying to write an automated test script for it.  Githug basically manipulates a directory to put it into different states of a working git repository and you can execute git commands to "solve" the level.</p>
  
  <p>One of the levels asks you for your git config details and I am doing the following:</p>
  
  <pre><code>#! /bin/sh
  # ...snip
  #level 4
  FULL_NAME=$(git config --get user.name)
  EMAIL=$(git config --get user.email)
  echo -e "$FULL_NAME\n$EMAIL" | githug
  </code></pre>
  
  <p>When I execute from a bash script it (echo -e) doesn't work.  But it does when I run it from the terminal.</p>
  
  <pre><code>FULL_NAME=$(git config --get user.name)
  EMAIL=$(git config --get user.email)
  echo -e "$FULL_NAME\n$EMAIL" | githug

  What is your name? What is your email?
  Congratulations, you have solved the level

  <p>Why doesn't this work from the bash script?</p>
  
  <p>Thanks.</p>
