This article is to share with you about how to determine the linux version number. The editor thought it was very practical, so I shared it with you as a reference. Let's follow the editor and have a look.

How to determine the linux version number? In fact, when people refer to Linux, they usually refer to the Linux distribution; but strictly speaking, Linux is a kernel, while the Linux distribution is an operating system made up of the Linux kernel, GNU tools and libraries, and software collections.

How does linux check the version number?

Method 1: use the uname command to check the linux kernel version number

The uname command displays multiple system information, including the Linux kernel architecture, name version, and release.

To find out which version of the Linux kernel is running on the system, type:

Uname-srm

Output

Linux 4.9.0-8-amd64 x861464

The above output tells us that the Linux kernel is 64-bit and its version is "4.9.0-8-amd64".

Method 2: use the hostnamectl command

Hostnamectl is part of systemd and can be used to query and change the system hostname. The command also displays the Linux distribution and kernel version.

Hostnamectl

Output:

Static hostname: debian9.localdomaincon name: computer-vmChassis: vmMachine ID: a92099e30f704d559adb18ebc12ddac4Boot ID: 7607cbe605d44f638d6542d4c7b3878eVirtualization: qemuOperating System: Debian GNU/Linux 9 (stretch) Kernel: Linux 4.9.0-8-amd64Architecture: x86-64

The above output tells us that the Linux kernel is 64-bit and its version is "4.9.0-8-amd64"; the release is "Debian GNU/Linux 9 (stretch)" with version number 9.

Method 3: use the lsb_release command

Lsb_release applications can display LSB (Linux Standard Library) information about Linux distributions; this lsb_release command applies to all Linux distributions that have lsb-release packages installed:

Lsb_release-a

Output:

No LSB modules are available.Distributor ID:DebianDescription:Debian GNU/Linux 9.5 (stretch) Release:9.5Codename:stretch

The Linux release and version are displayed in the "Description" line. As you can see from the output above, Debian GNU / Linux 9.5 (stretch) is installed on my system.

Method 4: use the cat / etc/os-release command

The / etc / os-release file contains operating system identification data, including information about distribution. This file is part of systemd and should be available on linux systems running systemd.

To view the contents of the os-release file, you need to run the following cat command:

Cat / etc/os-release

The output is as follows:

PRETTY_NAME= "Debian GNU/Linux 9 (stretch)" NAME= "Debian GNU/Linux" VERSION_ID= "9" VERSION= "9 (stretch)" ID=debianHOME_URL= "https://www.debian.org/"SUPPORT_URL="https://www.debian.org/support"BUG_REPORT_URL="https://bugs.debian.org/"

Method 5: use the cat / etc/issue command

The / etc/issue file contains the system identification text that is displayed before the login prompt. Typically, this file contains information about the Linux version:

To view the contents of the issue file, you need to run the following cat command:

Cat / etc/issue

The output is as follows:

Debian GNU/Linux 9\ n\ l Thank you for reading! On how to determine the linux version number to share here, I hope the above content can be of some help to you, so that you can learn more knowledge. If you think the article is good, you can share it and let more people see it.
