title: Unable to locate Jenkins file when Jenkins is installed over Tomcat on Linux Machine
body: <p>Unable to locate Jenkins file when Jenkins is installed over Tomcat on Linux Machine</p>
  
  <p>I have installed Jenkins(Jenkins.war) on a Linux (RedHat) machine using Tomcat application server.Prior to installation I had set my JENKINS_HOME(in ~/.bash_profile) to /apps/jenkins folder so that Tomcat will install Jenkins on this directory.</p>
  
  <p>Post installation Jenkins is up and running and my jobs are executing fine.However, I need to change JENKINS_USER to other user but I am not able to locate the Jenkins file that will have info like JENKINS_USER and JENKINS_PORT.
  I tried searching this file under following directories but no success.</p>
  
  <pre><code>/var/lib/jenkins 
  /etc/sysconfig 
  /etc/default
  </code></pre>
  
  <p>I am not able to find it even in the Jenkins installation directory.</p>
  
  <p>Any help would be appreciated.</p>
  
  <p>Thanks</p>
