title: Call one shell script from another script using relative paths
body: <p>I have a script like this:</p>
  
  <pre><code>#!/bin/csh
  echo "This is the main programme"
  ./printsth
  </code></pre>
  
  <p>I want to call the script <code>printsth</code> from within this script using relative paths. Is there a way to do so? By relative paths I mean path relative to where my calling script is.</p>
