title: executing shell script without calling sh implicitly
body: <p>I was wondering if it is possible to make a "link" in usr/bin (i.e.) that leads to a shell-script.</p>
  
  <p>But I want just to write </p>
  
  <pre><code>% shellscript
  </code></pre>
  
  <p>instead of</p>
  
  <pre><code>% sh shellscript.sh
  </code></pre>
  
  <p>kinda like an alias.</p>
  
  <p>Is this possible?</p>
