title: Initializing variables in bash
body: <p>I'm migrating windows CMD script to bin/bash on unix.
  The goal of initial script was to setting up some variables, so after anything run from this cmd window was using that variables.
  How can I do same in UNIX? Looks like simple</p>
  
  <pre><code>MyVar="value"
  </code></pre>
  
  <p>doesn't work. It visible only in script itself, not from terminal where it was run.</p>
