emacsclient

Open files in an existing Emacs server. See also emacs. More information: https://www.emacswiki.org/emacs/EmacsClient.

• Open a file in an existing Emacs server (using GUI if available):
   
  emacsclient {{path/to/file}}
   
• Open a file in console mode (without an X window):
   
  emacsclient --no-window-system {{path/to/file}}
   
• Open a file in a new Emacs window:
   
  emacsclient --create-frame {{path/to/file}}
   
• Evaluate a command, printing the output to stdout, and then quit:
   
  emacsclient --eval '({{command}})'
   
• Specify an alternative editor in case no Emacs server is running:
   
  emacsclient --alternate-editor {{editor}} {{path/to/file}}
   
• Stop a running Emacs server and all its instances, asking for confirmation on unsaved files:
   
  emacsclient --eval '(save-buffers-kill-emacs)'
