Exiting zsh with jobs in background

Exiting zsh with jobs in background

[Steve Talley]

Is there any way to turn off the "zsh: you have running jobs." message
that appears when you try to exit zsh with jobs in the background?  I
have the "nohup" option set so that zsh won't kill those jobs, but I'd
like to be able to exit the shell without being nagged about running
jobs.

Also...

When zsh has multiple completion possibilities, it gives the the
error:

zsh: do you wish to see all <n> possibilities?

What is the minimum value of n such that this message will appear?  Can
I change this value or disable the message entirely?

There is no way to turn it off.  I once posted a patch that made zsh
behave like bash in that respect (i.e. not to warn about running job
when nohup is set), but it was rejected.

On the small number of occasions I actually i) log out, and ii) have
jobs running, and hence get the warning, I just disown them.

If I was really keen, maybe I'd have done something in .zlogout to
disown all my running jobs.

But the warning doesn't happen only in login shells.  Each time I
press C-d in my xterm or screen terminal, I get the warning.  Note
that the warning really is unnecessary because the nohup is set, so
zsh will do nothing about the jobs.

Yes, you can do that, but the goal of the patch was to enhance the
default behaviour for a casual user.  I know one can get all of it
through .zlogout.

Just because zsh won't kill the jobs doesn't mean that the warning is
useless, if I suspend my mailer, editor, etc. and then forget about it,
I want to be reminded before I exit the shell.

 To err is human -- to blame it on a computer is even more so.

But the warning will remain for suspended processes.


P.S.
This strangely reminds me a similar discussion back then. :-)

You don't need to disown them when they are started with nohup, you
just have to hit ^D once more to logout. But that sometimes *is*
annoying. 

   If I was really keen, maybe I'd have done something in .zlogout to
   disown all my running jobs.

How would one do that elegantly? While zsh writes the output of "jobs"
to a file (which I wouldn't name the most elegant solution), it starts
a subshell which won't see the jobs of its parent if you either pipe
it into e.g. xargs or try to put it into a variable, e.g.
JOBS=(`jobs`)

Just curious.

It's not an error message.

Whatever would cause the list not to fit on the screen.

You can change $LISTMAX to some fixed number.  To disable the message,
set it to something large.

I don't need to disown them at this point -- since I have nohup set I just hit
Ctrl-D again and the shell exits.  The problem is that I want to avoid the
message if I can.  Having nohup set should allow me to do this...

By the time .zlogout gets sourced it is too late to disown the jobs.  You could
put a function in precmd that disowns jobs immediately, but then you lose job
control.  Clearly a "nowarn" option is needed for zsh.
