2.init 6 tells the init process to shutdown all of the spawned processes/daemons as written in the init files (in the inverse order they started) and lastly invoke the shutdown -r now command to reboot the machine init 0 powers down the system, so it is analogous to "shutdown -P now". shutdown -h only halts the system. Personally, as a longtime UNIX user, I generally use init 0, or init 6 to reboot. I have never noticed any harmful effects. Tim.

This ensures that daemons clean up themselves before shutdown. 4) Init Command The init command is used to change the runlevel of the Unix/Linux system. These system runlevels are 0-6. The runlevel 0 is used for system halt. Init supports eight runlevels: 0 through 6 and S or s. The runlevel changes when a privileged user runs Telinit, which sends appropriate signals to Init, telling it which runlevel to change to. Runlevels 0, 1, and 6 are reserved.

The system is in runlevel 0 (single user mode), so there is no reduction of runlevel that can occur, so no shutdown scripts are automatically run. The system is in runlevel 6. What init 6 does it to put the system in runlevel 6. Again, there's nothing running init 6 will do that running the reboot command won't do.

Then, we will develop an equivalent Upstart job.. Writing a System V init script.

The Init is the parent of all processes with PID # 1. Its primary purpose is to create processes from a script stored in the file /etc/inittab file. This file usually has entries which cause init to spawn gettys on each line that users 2018-11-05 · SysV init launches scripts and “daemon” processes one at a time, in order for a given run level found in /etc/rc.#/ (Where # is a run level number from 0 to 6). Systemd is used in later versions of Linuxwhich is compatible with Unix SysV and Linux Standard Base (LSB) init scripts.

Each runlevel has a certain number of services stopped or started. You can change system runtime levels with it in much the same way as init except there is a slight delay even if you specify 0 delay :-) For init level 0, no wait time, dont ask for confirmation: shutdown -g0 -i0 -y. For init level 6, no wait time, dont ask for confirmation: shutdown -g0 -i6 -y. Unbeliever.
