> 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)'`
