   == Environment Variables
   
  
positive.code: The following is an example:
  
  ```console
  % RUBOCOP_SERVER_PORT=98989 rubocop --start-server
  ```
  
negative.code: If a server is already running, the command only displays the server's PID. A new server will not be started.
  
  ```console
  $ rubocop --start-server
  RuboCop server (16060) is already running.
  ```
  
  The server process name is basically `rubocop --server` and the project directory path:
  
  ```console
  $ ps aux | grep 'rubocop --server'
  user             16060   0.0  0.0  5078568   2264   ??  S     7:54AM   0:00.00 rubocop --server /Users/user/src/github.com/rubocop/rubocop
  user             16337   0.0  0.0  5331560   2396   ??  S    23:51PM   0:00.00 rubocop --server /Users/user/src/github.com/rubocop/rubocop-rails
