This article will explain in detail what is the use of the uname command in Linux. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Linux common command uname command is used to display system information, uname can display computer and operating system related information.

Uname prints system information.

Summary uname [OPTION]... The main purpose is to print information about machines and operating systems.

When there is no option, the-s option is enabled by default.

If multiple options or the-an option are given, the output is sorted by the following fields: kernel name, host name, kernel release, kernel version, machine name, processor hardware platform operating system.

The option-a,-- all prints all the information in order, omitting if the information for-p and-I is unknown. -s,-- kernel-name prints the kernel name. -n,-- nodename prints the host name of the network node. -r,-- kernel-release prints kernel release. -v,-- kernel-version prints the kernel version. -m,-- machine prints the machine name. -p,-- processor print processor name. -I,-- hardware-platform print hardware platform name. -o,-- operating-system prints the operating system name. -- help displays help information and exits. -- version displays version information and exits. A return value of 0 indicates success, while a non-zero value indicates failure.
