[Chicago-talk] system command to kill Xwindows session?

[Alexander Danel]

You didn't telll me if you are on UNIX.

The "startx" script has to give you the PID, which it currently isn't doing,
and then you have to gather the PID.

In "startx", assuming Unix

	$!/bin/ksh
	Foobar &
	echo $!

I assume you are using the '&' to background "Foobar".  The '$!' gives you
pid of background job, but must be immediately following "Foobar &" command.

In Perl, you gather the echoed PID by using "qx" instead of system()

my $thePid = qx/startx/;

Now you can kill $thePid.

Got to go.  Goodluck, bye.

Alexander

I have script that starts an xwindows session with system("startx") I want
it to end as soon as a specific tast is done?
