title: Enter password only once for three "git clone"s in a script
body: <p>I want to create a bash script in Linux with clone repositories from git.
  I want to write the script in the way that I want need to type the username and password. </p>
  
  <p>My script looks:</p>
  
  <pre><code>#!/bin/bash
  git clone http://xxx
  git clone http://yyy
