title: Does the dot command behave uniformly across different shells?
body: <p>You can use the <code>.</code> command to execute commands from a shell script as if they were in the calling shell script itself.</p>
  <p>If I use the <em><strong>dot</strong></em> command in my shell scripts, will it behave similarly across different shell interpreters?</p>
  <p>PLEASE Note: I'm <strong>not asking</strong> about the difference between the <code>.</code> command and the <code>source</code> command. If that's what you want to learn, please see this other question: <a href="https://stackoverflow.com/questions/20094271/using-dot-or-source-while-calling-another-script-what-is-the-difference">Using dot or &quot;source&quot; while calling another script - what is the difference?</a></p>
