I'm a relatively new Sage user, trying Jupyter for the first time. OS is
Ubuntu 14.04; Sage version is 8.1. Starting Jupyter from the command line
(sage -n jupyter) works as expected, but so far as I can tell the only way
to shut down the notebook server after closing the browser is via ctrl-c.
What if sage is not started from a terminal? Or if stdout is redirected
to a file? For example, if I redirect stdout when starting sage, then send
ctrl-c after closing the browser, the sage-notebook process continues to
run -- presumably because I have no way to send a second ctrl-c.
I found this 10-year-old post asking essentially the same question:
https://groups.google.com/forum/#!newtopic/sage-support/sage-support/IrA6obQupKw
but parts of it are clearly out of date. However, the suggestion to use
"kill -2" sounds promising, but on which process? I only see two, one
running sage-notebook, the other running sage-cleaner. Or is there some
other way? "killall python" works, but presumably isn't a clean shutdown
-- and I certainly wouldn't want to script such a sledgehammer.
It would be really nice if there were a provided script for shutting down
the notebook server cleanly!
