title: Call function from another shell script
body: <p>I have write a script, and I like to now to make it better readable, by moving parts of my main script in other files, but unfortunately I cannot.</p>
  
  <p>Let's say now I have the following code in file <code>utils.sh</code>:</p>
  
  <pre><code>#!/bin/bash
  
  sayHello ()
  {
     echo "Hello World"
  }
  </code></pre>
  
  <p>Them from my main script I try the following, but doesn't work:</p>
  
  <pre><code>#!/bin/bash
  
  ./utils.sh
  
  sayHello
  </code></pre>
  
  <p>So, the question is, how to call the functions from within the utils.sh ?</p>
