title: Accessing Google Compute Engine as a different ssh user
body: <p>I ssh onto GCE and submit a job using the following command:</p>
  
  <p>gcutil ssh vmName sh /bin/someScript.sh</p>
  
  <p>This works fine. Now I'd like to run the job under a different user on the GCE, I tried:</p>
  
  <p>gcutil ssh -ssh-key-file MY_SSH_KEY_FILE anotherUser@vmName sh /bin/someScript.sh</p>
  
  <p>it didn't work throwing error: "FATAL Flags parsing error: option -s not recognized"</p>
  
  <p>Can anybody tell me what's wrong in the command? or more things need to be done?</p>
