title: bash script order of execution
body: <p>Do lines in a bash script execute sequentially? I can't see any reason why not, but I am really new to bash scripting and I have a couple commands that need to execute in order.</p>
  
  <p>For example:</p>
  
  <pre><code>#!/bin/sh
  # will this get finished before the next command starts?
  ./someLongCommand1 arg1
  ./someLongCommand2 arg1
  </code></pre>
