Contrl-Z action.

Contrl-Z action.

[Alexey Solovyov]

Hi, guys,

It seems to me that the mailing lists are not very popular among zsh
guys. Or we really have nothing to talk about? 

But I've got a question. Once I came up why I want to have my job
suspended by pressing Cntrl-Z ? Ok, I want it to run in background
right after that. In another words how to (where) redefine action of
Ctrl-Z?  Any comments why nobody should change it are also very
welcome.

All the best,

Ctrl-Z "suspends" the job.  For job control, use:

ps, jobs, bg, fg

commands to move around. :)
Take a look at these... They're quite useful (at least for me... I use it
everyday :P   ).

I can't think of a elegant way of doing this automatically without a lot of
overhead.  What you could do is

% bindkey -s "^Z" "bg^M"

then when you suspend something, press CTRL-Z again and it will put it in the
background.

Thanks, I will probably do it this way though actually I was thinking
about changing the sources... :)

But anyway suggestions about eliminating the second Ctrl-Z are welcome.

Eww, don't do that.

} But anyway suggestions about eliminating the second Ctrl-Z are welcome.

    function autobg() {
	jobs -s >| /tmp/j$$
	while read jnum jdesc
	do
	    bg %${${jnum#\[}%\]}
	done < /tmp/j$$
	rm -f /tmp/j$$
    }

    function precmd() {
	autobg
    }

I really question whether this is the behavior you want, though.  You
might want to change the `bg ...' command in autobg to something like

	case $jdesc in
	(*( vi | vim | *emacs )*) ;;	# Don't autobg any editors,
	(*) bg %${${jnum#\[}%\]} ;;	# but anything else is OK.
	esac

or possibly something even more restrictive where you list the things
that you *do* want to autobg rather than those that you don't.
