Why does huponexit not work in the following?
Bash manual says
If the huponexit shell option has been set with shopt (see Section 4.3.2 [The Shopt
Builtin], page 62), Bash sends a SIGHUP to all jobs when an interactive login shell exits.
Why does huponexit not work in the following?
In one interactive shell
$ shopt -s huponexit
$ sleep 4321 &
[1] 13816
$ exit
Then in the other shell
$ ps -j 13816
PID PGID SID TTY STAT TIME COMMAND
13816 13816 13728 ? S 0:00 sleep 4321
Thanks.

when an interactive login shell exits
is significant.
$ bash -l
$ shopt -s huponexit
$ sleep 120 &
[1] 24235
Then CtrlD exits (with logout, instead of exit as in your example), and
$ ps -j 24235
PID PGID SID TTY STAT TIME COMMAND
The sleep was killed too.
