Re: Quitting all active applications



I had always naively assumed that all the some *Framework underneath an app was setting up signal handlers for you with default behaviours. If this isn't the case, then yes any killall approach will cause loss of data.

Now I'm interested into finding out why this isn't the case.

Randal is correct, this will lose your saved data in any currently
open applications.

Actually no, since the default kill signal is TERM, apps will be allowed to
prompt to save if necessary. This assumes the app is handling that signal
properly. We could send KILL or ABRT and that would just end the processes
w/o any save options.

A small app that utilized an NSTask object whose system command would be
'killall -u <your short username here> -m <regex>'.
And that would be a great way to lose data, if any of the applications
getting killed had unsaved documents.
