Send command to emacs from external process

Send command to emacs from external process

[Joe Riel]

Frequently I'll have Emacs running on a machine,
with an unsaved buffer, and would like to save the
buffer but no longer have access to the terminal
(i.e. it's in a different room and I'm too lazy to
walk over there).  I can login in to the machine
remotely.  Is there a way to tell Emacs to save
the buffer?

One thing I can think of is to use Screen, and then after you ssh in, you
just attach to the screen, and everything is there.. the entire environment

Or simply run emacs as a server. (info "(emacs)Emacs Server")

Thanks, that's exactly what I want.

And when it's tool ate to start the server, you can kill the Emacs
process (with a soft signal, not like SIGKILL, of course), and Emacs
will autosave the buffers so they're ready for recovery.
