GNU / Linux GUI already foundmany fans and is becoming increasingly popular today. The number of distributions is growing rapidly, so you need to be able to understand which is the most optimal. And this is true, because Linux is a free graphical interface, which is rightfully the most successful around the world. Often, the user needs to know the version of Linux, for example, to install any programs built for certain versions. Their numbers are calculated in the form "Year.Month" (or "YY.MM"). Thus, these figures indicate the release date of the distribution. Another important point is that each release must have its own code name, for example "Karmic" or "Lucid Lynx".
What actually is the core, what are the differencesthese cores, why develop them constantly and give them an account? The kernel is the central link of the system, it has a very large size, but it also contains an ordered and clear hierarchy of different levels. Its main components are: system calls (SCI), process management (PM), memory management (MM), as well as virtual file system (VFS), network stack and various device drivers. Finding the version of Linux means also finding information about the kernel. For ordinary users who are not too versed in the field of working with software, they have to deal with it extremely rarely, because not everyone will be able to cover all the important and subtle aspects of this software level. Versions differ in the interaction with the equipment, drivers and speed. And all that the user uses is only a surface shell and GNU applications (this prefix must be present before the Linux inscription in the system version).
The user can find out the Linux version by differentin ways. For example, there is the utility "lsb_release", which can be used together with the –a key. You must first go to the command line, and then type the command. It may not be possible to install it, then the program will have to be downloaded from the repository. After entering the screen will show the name of the distribution and its version.
You can see the Linux version by typing "cat / etc / issue". After this, the following data should be displayed on the monitor: Debian GNU / Linux 6.0 n l or Ubuntu 12.04.2 LTS n l.
The version of the kernel itself is recognized using the specified "uname –r" function, but if instead of the last prefix you write –a, then all the information on this command will be output.
Also, if it is impossible to log in, find outLinux version can be by rebooting the system unit and in the download menu to find all the most necessary information. This method serves to identify which distribution is used.
Информация о Linux системе хранится также в файле / etc / lsb-release. Therefore, to open it, the following command is entered in the terminal: cat / etc / lsb-release. You can also find out the version in the Linux GUI system from the user manual.
So, various systems of the Linux family, beingquite complex, they provide fairly simple and accessible methods for determining the distribution version and kernel number. There are several options for viewing both using the terminal and without it.
