attaching to a running emacs process under linux?

attaching to a running emacs process under linux?

[ivowel]

is there a way to send a shell signal to ask emacs nicely to save all
its open buffers?  I sometimes forget to save my buffers, then go
somewhere else and ssh into the original machine, just to find that
emacs still has my unsaved changes.

Make sure Emacs server is running and use the following command:

    $ emacsclient -e '(save-some-buffers t)'

I guess that is not what the OP had in mind. I guess he is experiencing
some autosave feature.

Read about sigusr1 and sigusr2 events in the "Misc Events" node of the
ELisp manual.  You will need to write some Lisp in your ~/.emacs to
bind these events to some function that calls save-some-buffers or
some such.

If worse comes to worst, you can always send SIGTERM to Emacs: Emacs
always auto-saves before it terminates in an abnormal fashion.
