title: How to install git bash on ubuntu?
body: <p>I am new to Ubuntu. Previously I was on Windows and was using <code>git bash</code> for <code>git</code> commands.
  But I have decided to use Ubuntu and I installed <code>git</code> but I am not sure whether it is necessary to install <code>git bash</code> on Ubuntu? And, if it is necessary, how should I install it?</p>
