Bug Description

Binary package hint: bash

Option huponexist is set to be off but bash still close background jobs. I remember before Maverick and maybe Lucid that background jobs did not close even if you close the terminal. So this is a regression.

This is normal behavior that has never changed. When a terminal is closed, the kernel sends SIGHUP to all attached processes. It has nothing to do with bash. The usual method of allowing a program to run in the background after closing the terminal is to run it with the nohup program.

If you can get a backgrounded job to remain running after closing the terminal ( other than by using nohup ) on lucid, could you describe how?

As I said that previous version you could run like firefox & and close the terminal and it still run.
The problem now is even if I disable huponexit it still close!

Strangely, that works for me in maverick, even though it shouldn't.

Figured it out. When you use the command exit the jobs will remain. These upstream developers are vexing me.
It is the same thing they did with history save. Until they changed it back.

A temporary fix is to add <trap "disown -ah" HUP> to ~/.bashrc . Change option a to r for running jobs only.
Might want to do <trap "exit" HUP> incase these upstream developers wanted to make history save on exit only.
