	`7`	+If you use KDE 5 based distributions like KDE Neon (formerly KUbuntu), Manjaro KDE, etc. you use both scripts namely, `graceful-shutdown.sh` and `kde-graceful-shutdown.sh`.
	`8`	+On other systems use only `graceful-shutdown.sh` script. In either case, change `programs_list` variable in `graceful-shutdown.sh` to your usecase.
	`9`	+Make sure both scritps are in `PATH` variable of your desktop environment shell or you provide absolute path to them.
