title: Running csh script from bash script
body: <p>I am writing a script that requires a initial setup.
  the setup is in the form of csh script that has many artifacts on the environment variables.
  right now when i'm executing the csh from within the bash, the variables inside the subshell of the bash are left unchanged.</p>
  
  <p><strong>example:</strong></p>
  
  <pre><code>#!/bin/bash 
  echo $PATH
  setevnvar.csh -dir $ROOT_DIR/
  echo $PATH
  </code></pre>
  
  <p>in this example I would to see that the PATH variable is changed after running the csh script (it is one of the results)</p>
  
  <p>would appreciate any thoughts.</p>
