NAME emacsclient - tells a running Emacs to visit a file

SYNOPSIS emacsclient [options] files ...

DESCRIPTION This manual page documents briefly the emacsclient command. Full docu- mentation is available in the GNU Info format; see below. This manual page was originally written for the Debian GNU/Linux distribution, but is not specific to that system.

emacsclient works in conjunction with the built-in Emacs server.

You can either call emacsclient directly or let other programs run it for you when necessary. On GNU and Unix systems many programs consult the environment variable EDITOR (sometimes also VISUAL) to obtain the command used for editing. Thus, setting this environment variable to emacsclient will allow these programs to use an already running Emacs for editing. Other operating systems might have their own methods for defining the default editor.

For emacsclient to work, you need an already running Emacs with a server. Within Emacs, call the functions server-start or server- mode. (Your .emacs file can do this automatically if you add either (server-start) or (server-mode 1) to it.)

When you ve finished editing the buffer, type C-x # ( server-edit). This saves the file and sends a message back to the emacsclient pro- gram telling it to exit. The programs that use EDITOR wait for the "editor" (actually, emacsclient) to exit. C-x # also checks for other pending external requests to edit various files, and selects the next such file.

If you set the variable server-window to a window or a frame, C-x # displays the server buffer in that window or in that frame.

OPTIONS The programs follow the usual GNU command line syntax, with long options starting with two dashes (-).

-nw, -t, --tty open a new Emacs frame on the current terminal

-c, --create-frame create a new frame instead of trying to use the current Emacs frame

-e, --eval do not visit files but instead evaluate the arguments as Emacs Lisp expressions.

-n, --no-wait returns immediately without waiting for you to "finish" the buffer in Emacs.

-s, --socket-name=FILENAME use socket named FILENAME for communication.

-f, --server-file=FILENAME use TCP configuration file FILENAME for communication. This can also be specified via the EMACS_SERVER_FILE environment variable.

-a, --alternate-editor=EDITOR if the Emacs server is not running, run the specified editor instead. This can also be specified via the ALTERNATE_EDITOR environment variable. If the value of EDITOR is the empty string, then Emacs is started in daemon mode and emacsclient will try to connect to it.

-d, --display=DISPLAY tell the server to display the files on the given display.

-V, --version print version information and exit

-H, --help print this usage information message and exit

SEE ALSO The program is documented fully in Using Emacs as a Server available via the Info system.
