Re: How to execute commands at vim exiting?

A bit better solution:

autocmd VimLeave * !screen -ls vim_${PPID} | grep vim_${PPID} &&
dialog --yesno "Leave existing screen sessions alive?" 6 40 && screen
-r vim_${PPID} || kill $(screen -ls vim_${PPID} | perl -ne
's/^.*?(\d{2,}).*$/\1/&&print') && clear

...this way vim exits anyway but, at least, attach the screen helping
user to propperly close windows and running proceses.
