title: Scripting on Linux
body: <p>I am trying to create a script that will run a program on each file in a list.  I have been trying to do this using a .csh file (I have no clue if this is the best way), and I started with something as simple as hello world</p>
  
  <pre><code>echo "hello world"
  </code></pre>
  
  <p>The problem is that I cannot execute this script, or verify that it works correctly.  (I was trying to do ./testscript.csh which is obviously wrong).  I haven't been able to find anything that really explains how to run C Scripts, and I'm guessing there's a better way to do this too. What do I need to change to get this to work?</p>
