To view the current Linux version, you can use the following methods: 1. Use uname -r or uname -a to view the kernel version and system basic information; 2. Use lsb_release -d to view the distribution name, version number and code; 3. If there is no lsb_release, you can use cat /etc/os-release to view the system version details; 4. For CentOS, RHEL or Fedora old versions, you can view the /etc/redhat-release or /etc/centos-release file; 5. In the graphical interface, you can view the system version information through "Settings" or "About Native", which is suitable for desktop users.

View full system version information

The easiest way is to use uname -r or uname -a . This command will display information such as kernel version, release time, hardware architecture, etc. of your current system.
For example, you run:

 uname -r

The output might look something like this:

This information is helpful for troubleshooting driver compatibility or confirming the software packages supported by the system.

If you need more comprehensive information, including the release name, version number and code name, you can use the following command:

 lsb_release -d

The output is probably:

 Ubuntu 22.04.2 LTS

This is especially useful for confirming whether you are using CentOS, Debian, Ubuntu, or other distributions.

Quickly view the content of the release file

Sometimes you may not have installed the lsb_release command, and you can directly view the /etc/os-release file:

 cat /etc/os-release

This file usually has fields such as NAME , VERSION_ID , VERSION_CODENAME , etc., which clearly tell you what version of the current system is.

If it is an old version of CentOS, RHEL or Fedora, you can also check out the /etc/redhat-release or /etc/centos-release file, which usually directly writes the system name and version.

You can also see it in the graphical interface

If you are using Linux with a desktop environment (such as GNOME or KDE), you can actually check it through the graphical interface.
The system version can usually be seen in "Settings" or "About Native". The path may be slightly different, but generally not too difficult to find.


Basically these are the methods. You can choose different methods for different scenarios. The command line is suitable for remote operations, and the graphical interface is more intuitive.
