Linux Desktop How to shutdown, restart or logoff gnome via command / Launcher
It is true that Gnome desktop provides nice facility to logoff, shutdown or restart computer with dialog. You can create a nice shortcut to avoid the GUI confirmation dialog box to speed up work.
(A) Shutdown computer
i) Right click on Desktop > Select Create Launcher
ii) Type the Command in text box “sudo /sbin/shutdown -h 0” and for rest of properties refer following figure:
iii) Click Close to save. Please note that only root will be able to shutdown system. However with the help of sudo it is possible that non-privileged can also shutdown the system (without password). Type following commands:
a) Login as root user
b) Type visudo command:
#visudo
c) Append following text of line, so that all commands will be excuted without password.
vivek localhost= NOPASSWD: /sbin/shutdown -h 0
vivek localhost= NOPASSWD: /sbin/reboot
By default, sudo requires that a user authenticate him or herself before running a
command. This behavior is modified with NOPASSWD flag i.e. shutdown and reboot command would allow user vivek run as root on the localhost as root without authenticating (password) himself
