I was trying to save in Emacs and pushed something wrong and Emacs closed. Judging by
ps aux | grep emacs
the emacs
process is still running with the file I need to save running. (Opening the file in new emacs
process complains that the file is used by another emacs
process).
How can I reattach to the running Emacs session or at least make it save its work before I kill it?
