This article mainly introduces the use of linux halt command shutdown, the article is very detailed, has a certain reference value, interested friends must read it!

The halt command is used to shut down the running Linux operating system, which should be executed carefully if it is an online server that has lost business.

The halt command first detects the runlevel of the system, shuts down the system if runlevel is 0 or 6, otherwise calls shutdown to shut down the system.

Syntax format: halt [parameters]

Common parameters:

-w does not really restart or shut down, just write wtmp (/ var/log/wtmp) record-d does not write wtmp record (already included in option [- n])-f does not call shutdown but forces shutdown or restart-I shutdown (or restart) all network interfaces-p this option is the default option, that is, poweroff is called when shutdown

Reference example

Shut down the operating system using the-p parameter, which is equivalent to the poweroff command, and power off the operating system:

[root@linuxcool] # halt-p

Use the-f parameter to force the shutdown, and the operating system is not powered off:

[root@linuxcool] # halt-fHalting. The above is all the contents of shutting down using linux's halt command, thank you for reading! Hope to share the content to help you, more related knowledge, welcome to follow the industry information channel!
