Invoking emacsclient
To run the emacsclient program, specify file names as arguments,
and optionally line numbers as well. Do it like this:
emacsclient {[+line[column]] filename}...
This tells Emacs to visit each of the specified files; if you specify a
line number for a certain file, Emacs moves to that line in the file.
If you specify a column number as well, Emacs puts point on that column
in the line.
Ordinarily, emacsclient does not return until you use the
C-x # command on each of these buffers. When that happens,
Emacs sends a message to the emacsclient program telling it to
return.
But if you use the option -n or --no-wait when running
emacsclient, then it returns immediately. (You can take as
long as you like to edit the files in Emacs.)
The option --alternate-editor=command is useful when
running emacsclient in a script. It specifies a command to run
if emacsclient fails to contact Emacs. For example, the
following setting for the EDITOR environment variable will
always give an editor, even if Emacs is not running:
EDITOR="emacsclient --alternate-editor vi +%d %s"
The environment variable ALTERNATE_EDITOR has the same effect, but
the value of the --alternate-editor takes precedence.
Alternatively, the file etc/emacs.bash defines a bash
function which will communicate with a running Emacs server, or start
one if none exists.
