Full Discussion: Kill child processes, when parent is "bash"
Top Forums UNIX for Dummies Questions & Answers Kill child processes, when parent is "bash" Post 302376889 by teras on Wednesday 2nd of December 2009 02:46:47 PM

I know that I can programmatically parse the whole tree and recursively kill all children.
But it seems to me that this is has a big overhead.

Isn't there any other way to do it?
I thought this was the default behaviour, the childer to be killed when the parent gets killed.

xkill

XKILL(1)						      General Commands Manual							  XKILL(1)

NAME

       xkill - kill a client by its X resource

SYNOPSIS

       xkill [-display displayname] [-id resource] [-button number] [-frame] [-all]

DESCRIPTION

       Xkill  is  a  utility for forcing the X server to close connections to clients.	This program is very dangerous, but is useful for aborting
       programs that have displayed undesired windows on a user's screen.  If no resource identifier is given with -id, xkill will display a  spe-
       cial  cursor  as  a prompt for the user to select a window to be killed.  If a pointer button is pressed over a non-root window, the server
       will close its connection to the client that created the window.

OPTIONS

       -display displayname
	       This option specifies the name of the X server to contact.

       -id resource
	       This option specifies the X identifier for the resource whose creator is to be aborted.	If no resource is  specified,  xkill  will
	       display a special cursor with which you should select a window to be kill.

       -button number
	       This  option specifies the number of pointer button that should be used in selecting a window to kill.  If the word "any" is speci-
	       fied, any button on the pointer may be used.  By default, the first button in the pointer map (which is usually the  leftmost  but-
	       ton) is used.

       -all    This  option  indicates	that  all clients with top-level windows on the screen should be killed.  Xkill will ask you to select the
	       root window with each of the currently defined buttons to give you several chances to abort.  Use of this option is highly discour-
	       aged.

       -frame  This  option  indicates that xkill should ignore the standard conventions for finding top-level client windows (which are typically
	       nested inside a window manager window), and simply believe that you want to kill direct children of the root.

XDEFAULTS

       Button  Specifies a specific pointer button number or the word "any" to use when selecting windows.
