title: Customised command prompt is not saving chages after re-opening it
body: <p>I am trying to use PS1 to customise my command prompt in mac, but the changes are not saved, when I try to re-open the terminal.</p>
  
  <p>I have edited the .bashrc file, and the changes are effective only for that session. If I close and re-open the terminal, all saved changes are lost.</p>
  
  <p>Below is the .bashrc file that i have edited.</p>
  
  <pre><code>export PS1="\u@\h \d \@ \w &gt;"
  export PATH="/Users/avbanerj/test_script1:$PATH"
  </code></pre>
  
  <p>Could you please tell me what shall I add in my .bashrc or .profile so that changes are reflected everytime I open the terminal?</p>
