You are right. The script was running from clicking a python wx button, the issue I've just figured out is there is another command needs be run before it as following script.

exec su -l ${user}
killall gnome-panel

The "exec su -l ${user}" refreshed the change of user access permission, but lets user to log into another environment where the following "killall gnome-panel" won't afffect to the current parent environment which called script.

$ update_user_id.sh

In update_user_id.sh:

exec su -l ${user}
killall gnome-panel


The question is really, whether it is possible to make the subsequent login and changes to affect to parent environment? Or there is no way to make it work?

Thank you.

Kind regards.

$ update_user_id.sh


In update_user_id.sh:


exec su -l ${user}
killall gnome-panel

NAME
service - run a System V init script SYNOPSIS
service SCRIPT COMMAND [OPTIONS] service --status-all service --help | -h | --version DESCRIPTION
service runs a System V init script in as predictable an environment as possible, removing most environment variables and with the current working directory set to /. The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the invoked script. service passes COMMAND and OPTIONS to the init script unmodified. All scripts should support at least the start and stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start com- mand. service --status-all runs all init scripts, in alphabetical order, with the status command. EXIT CODES
service calls the init script and returns the status returned by it. FILES
/etc/init.d The directory containing System V init scripts. ENVIRONMENT
LANG, TERM The only environment variables passed to the init scripts. SEE ALSO
/etc/init.d/skeleton, update-rc.d(8), init(8), invoke-rc.d(8). Jan 2006 service(8)
