Why does huponexit not work in the following?












-1














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.

                    Is this a new Fibonacci Identity?

                    Image
                    6 1 $begingroup$ I have found the following Fibonacci Identity (and proved it). If $F_n$ denotes the nth Fibonacci Number, we have the following identity begin{equation} F_{n-r+h}F_{n+k+g+1} - F_{n-r+g}F_{n+k+h+1} = (-1)^{n+r+h+1} F_{g-h}F_{k+r+1} end{equation} where $F_1 = F_2 = 1$ , $r leq n$ , $h leq g$ , and $n, g, k in mathbb{N}$ . It is not too hard to show that this identity subsumes Cassini's Identity, Catalan's Identity, Vajda's Idenity, and d'Ocagne's identity to name a few. I have done a pretty thorough literature review, and I have not found anything like this, but I am still wondering if anyone has seen this identity before? I found this by accident after noticing some patterns in some analysis work I was doing, so if this is already known I would be curious to see w...
