EMACSCLIENT(1) General Commands Manual EMACSCLIENT(1)
NAME
emacsclient - tells a running Emacs to visit a file
SYNOPSIS
emacsclient [options] files ...
DESCRIPTION
This manual page documents briefly the emacsclient command. Full documentation is avail-
able 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 neces-
sary. 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 envi-
ronment 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 auto-
matically 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 program 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
Most options follow the usual GNU command line syntax, with long options starting with two
dashes ("-").
+line[:column]
Go to the specified line and column. A missing column is treated as column 1.
This option applies only to the next file specified.
-a, --alternate-editor=COMMAND
if the Emacs server is not running, run the specified shell command instead. This
can also be specified via the ALTERNATE_EDITOR environment variable. If the value
of ALTERNATE_EDITOR is the empty string, run "emacs --daemon" to start Emacs in
daemon mode, and try to connect to it.
-c, --create-frame
create a new frame instead of trying to use the current Emacs frame
-F, --frame-parameters=ALIST
set the parameters of a newly-created frame.
-d, --display=DISPLAY
tell the server to display the files on the given display.
-e, --eval
do not visit files but instead evaluate the arguments as Emacs Lisp expressions.
-f, --server-file=FILENAME
use TCP configuration file FILENAME for communication. This can also be specified
via the EMACS_SERVER_FILE environment variable.
-n, --no-wait
returns immediately without waiting for you to "finish" the buffer in Emacs. If
combined with --eval, this option is ignored.
-nw, -t, --tty
open a new Emacs frame on the current terminal
-s, --socket-name=FILENAME
use socket named FILENAME for communication. This can also be specified via the
EMACS_SOCKET_NAME environment variable.
-V, --version
print version information and exit
-H, --help
print this usage information message and exit
EXIT STATUS
Normally, the exit status is 0. If emacsclient shuts down due to Emacs signaling an er-
ror, the exit status is 1.
SEE ALSO
The program is documented fully in Using Emacs as a Server available via the Info system.
