EMACSCLIENT(1) General Commands Manual EMACSCLIENT(1)
emacsclient - tells a running Emacs to visit a file
emacsclient [options] files ...
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 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
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.
Most options follow the usual GNU command line syntax, with long
options starting with two dashes ("-").
Go to the specified line and column. A missing column is
treated as column 1. This option applies only to the next file
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, run "emacs --daemon" to start Emacs in daemon mode, and
try to connect to it.

tell the server to display the files on the given display.
do not visit files but instead evaluate the arguments as Emacs
use TCP configuration file FILENAME for communication. This can

print version information and exit

Normally, the exit status is 0. If emacsclient shuts down due to Emacs
signaling an error, the exit status is 1.
The program is documented fully in Using Emacs as a Server available
via the Info system.
