emacsclient

Open files in an existing Emacs server. See also emacs. More information: https://www.gnu.org/software/emacs/manual/html_node/emacs/emacsclient-Options.html.

• 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)'
