The environment is a list of keys and values mapped into a process' address space. kill (and killall which is a kill wrapper) does not affect it.

If you are using exec in a script, commands which follow will not execute because the exec'd command has replaced the shell.

You probably want to use su(1)'s -c option. I say "probably" because it's not clear to me what you're doing and under what circumstances you're doing it.

xdg-settings

XDG-SETTINGS(1) 						xdg-settings Manual						   XDG-SETTINGS(1)

NAME

       xdg-settings - get various settings from the desktop environment

SYNOPSIS

       xdg-settings {get | check | set} {property} [subproperty] [value]

       xdg-settings {--help | --list | --manual | --version}

DESCRIPTION

       xdg-settings gets various settings from the desktop environment. For instance, desktop environments often provide proxy configuration and
       default web browser settings. Using xdg-settings these parameters can be extracted for use by applications that do not use the desktop
       environment's libraries (which would use the settings natively).

       xdg-settings is for use inside a desktop session only. It is not recommended to use xdg-settings as root.

OPTIONS

       --help
	   Show command synopsis.

       --list
	   List all properties xdg-settings knows about.

       --manual
	   Show this manual page.

       --version
	   Show the xdg-utils version information.

PROPERTIES

       When using xdg-settings to get, check or set a destkop setting, properties and possibly sub-properties are used to specify the setting to
       be changed.

       Some properties (such as default-web-browser) fully describe the setting to be changed. Other properties (such as
       default-url-scheme-handler) require more information (in this case the actual scheme to set the default handler for) which must be provided
       in a sub-property.

EXIT CODES

       An exit code of 0 indicates success while a non-zero exit code indicates failure. The following failure codes can be returned:

       1
	   Error in command line syntax.

       2
	   One of the files passed on the command line did not exist.

       3
	   A required tool could not be found.

       4
	   The action failed.

EXAMPLES

       Get the desktop file name of the current default web browser

		   xdg-settings get default-web-browser

       Check whether the default web browser is firefox.desktop, which can be false even if "get default-web-browser" says that is the current
       value (if only some of the underlying settings actually reflect that value)

		   xdg-settings check default-web-browser firefox.desktop

       Set the default web browser to google-chrome.desktop

		   xdg-settings set default-web-browser google-chrome.desktop

       Set the default mailto URL scheme handler to be evolution.desktop

		   xdg-settings set default-url-scheme-handler mailto evolution.desktop
