title: Modifying LD_LIBRARY_PATH
body: <p>In UNIX, i am trying to modify the <code>LD_LIBRARY_PATH</code> to make it include some libraries i can't add to the regular libraries of the system( I don't have root permission it's a university server...), at this point I have used many ways that I came across the web to do this but could not modify it neither can i see what is the <code>PATH</code> ..
  I have tried using:</p>
  
  <pre><code>LD_LIBRARY_PATH="path-to-lib"
  </code></pre>
  
  <p>but got :command not found.</p>
  
  <pre><code>export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path-to-lib
  </code></pre>
  
  <p>but got: <code>bad modifier in $ (/)</code></p>
  
  <pre><code>export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/path-to-lib
  </code></pre>
  
  <p>but got: command not found</p>
  
  <pre><code>setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:/path-to-lib
  </code></pre>
  
  <p>but got:LD_LIBRARY_PATH: Undefined variable.</p>
  
  <p>I have got this solutions from:
  <a href="https://stackoverflow.com/questions/17071014/ld-library-path-without-export">LD_LIBRARY_PATH without export</a>
  and:
  <a href="https://stackoverflow.com/questions/13428910/how-to-set-the-environmental-variable-ld-library-path-in-linux">How to set the environmental variable LD_LIBRARY_PATH in linux</a> 
  and the comments.</p>
  
  <p>As recommended: my shell is -tcsh</p>
  
  <p>After countless attempts to see my LD_LIBRARY_PATH using all sorts of guides on web i used the printenv command and this is my output:</p>

  <p>I can't find my LD_LIBRARY_PATH in here, is it not supposed to be specified here?</p>
  
  <p>Thanks for your time!</p>
