title: Jenkins Update Syntax error: end of file unexpected (expecting ")") Execute Shell
body: <p>I am getting an error when trying to run a build on my Jenkins server. The following is what the output is showing. This happened after I updated to the latest version of Jenkins. I have also verified that all plugins are up to date.</p>
  
  <pre>
  [EnvInject] - Loading node environment variables.
  [workspace] $ /bin/sh -xe /tmp/hudson229576663898687231.sh
  /tmp/hudson229576663898687231.sh: 1: /tmp/hudson229576663898687231.sh: Syntax error: end of file unexpected (expecting ")")
  Build step 'Execute shell' marked build as failure
  Finished: FAILURE
  </pre>
  
  <p>Further debugging it appears that anytime I add an execute shell build option the error is thrown. For example inside the execute shell block.</p>
  
  <pre>
  ls -al;
  </pre>
  
  <p>Also the Jenkins installation is on an Ubuntu 12.10 machine.</p>
