This article introduces the relevant knowledge of "how to use the init command in Linux to shut down, restart, switch mode, etc.". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Linux has a file / etc/inittab

The code is as follows:

#

# inittab This file describes how the INIT process should set up

# the system in a certain run-level.

#

# Author: Miquel van Smoorenburg

# Modified for RHS Linux by Marc Ewing and Donnie Barnes

#

# Default runlevel. The runlevels used by RHS are:

# 0-halt (Do NOT set initdefault to this)

# 1-Single user mode

# 2-Multiuser, without NFS (The same as 3, if you do not have networking)

# 3-Full multiuser mode

# 4-unused

# 5-X11

# 6-reboot (Do NOT set initdefault to this)

#

Id:3:initdefault:

0 is the shutdown

1 is a single user

2 is multi-user and does not connect to the Internet.

3 is multi-user

4 is not used

5 is xwindows, that is, with an interface.

6 is reboot

The init command is simple. Just enter init + the mode you want and enter.

For example, enter "init 0" to shut down the computer.

Init 3 is to switch to multi-user.

Init 5 is to switch to the interface.

Init 6 is a restart.

When I experiment, I do it under root users. I don't know if other users can do it.
