If you're using Linux as the operating system on your computer, then you know perfectly well what kind of Linux is running there, but what if you need to connect to someone's server and do the same job? It's really helpful to know exactly what you're dealing with, and luckily it's very easy.
Like everything else in Linux, there are many ways to do this, so we'll show you a few different tricks and you can choose which one is best for you.
Run as a normal user the following script below. When you finish executing this script, this output will appear. So let's do it, open the file with your favorite editor and add these lines to the end of the file as shown in this image below.
Checking versions available for installation
Once you've done that, just run the command below to have your environment populated with the new config variables you've made. Your face will be very good help to understand commands. If you've been different and need some help, you can comment on this post or give me a call with some of the contacts on the left side of the blog. To see the versions available for use, run the following command.
How to see the Linux version name
The simplest and easiest way to see the title Linux distribution and version number on top of that and works on almost any Linux. Just open a terminal and type the following in there:
Cat /etc/issue
Before your eyes will appear something like what is shown in the screenshot at the top of this article, which looks something like this:
In the case where on my system I have system version, which was previously installed with my operating system, as well as version. Now let's jump to the system version and call the interpreter again to see what happens. Everything went perfectly!
Hope you enjoyed the post! But there is an even easier way. So, here's how to do it. This is another tutorial. Make the downloaded file executable with the following command. Move the file to the system binary folder. By default, the program will select the "best" test server for your locale. But if you want to determine this location manually, run the command below to display the available servers.
Linux Mint 17 Qiana
If you need more information you can use various teams, although they may not work on every distribution, they definitely work on the most popular ones. Just like before, open a terminal and type the following there:
Cat /etc/*release
You'll get something like the following screenshot, and you can see that not only is the release info here, but we've also been given a codename and even a URL. What really happened here is that on Mint there is a /etc/os-release file, but on other versions it might be something like /etc/redhat-release or a completely different name. By using * in the command, we simply output the contents of any of them to the console.
What is the command line for?
A list with the location code and name will be shown. To find a specific location by running the command. Duarte: enter the command below, after completion, you can get a link with a test. This page is under construction, rewriting or major restructuring. The text may contain erroneous information, and its content may be substantially changed. Also other pages for improvement and maintenance. This is a means of sending commands to the computer using commands consisting of character strings and entered into a window called "Console".
The easiest method is cat /etc/issue, of course, but the one we used is even better.
How to see the kernel version
The distribution version and the Linux kernel version are two completely different things. You can easily see the version number by opening a terminal and typing the following:
Uname -r
This will output something like the following, where we can see that kernel version 3.13.0 is being used.
You may be wondering: Why should I make the effort to learn these commands? You are usually right, but there are situations where the command line is very handy. Any graphic environment allows you to open the console in a single window. As a user, your rights are limited to protect the system.
File system navigation
The password is requested, but of course it is not displayed. Acts as a memory aid; if you don't remember the spelling of the command or the filename, type in the beginning and the system will list all relevant options. Save time Avoid typing errors. . You can also use the console as a file manager.
How to determine if a 64-bit kernel is being used or not
Sometimes the previous command can already tell if a 64-bit kernel is used, this can be determined by the x86_64 text, but the easiest way to do this is a command from the terminal, which is exactly the same command as the previous one, but with -a(this is called a key), which means "everything", instead of a key -r, which means "kernel release".
Simple commands to explore my computer
This partition cannot be mounted. You will get something like this.
Simple commands to change my computer
Attention! Here are a few commands that you will be happy to find if one day your computer stops working properly. You must install the directories manually before you can access them.Right click on the bottom left corner of the screen and select Control Panel in context menu. Right-click on the screen in the lower left corner and select "Control Panel" from the pop-up menu. When the Control Panel appears, select Programs and then Programs and Features.
- Click Programs.
- Click the "Start" button.
- When the Control Panel appears, select Programs.
- Click.
- Click Start.
- Select Control Panel.
- Select Programs.
- Click Programs and Features.
Uname-a
From this screenshot you can tell that x86_64 is running Linux version, which means 64-bit. If you were running 32-bit Linux, which you shouldn't be doing on a server, it would print "i386" or "i686" instead.
The nitpickers will probably notice that you can use the key -i to show if 32-bit or 64-bit is being used (useful in scripts), but it's better to just use -a to display everything at once.
We can say that this is a kind of spare tire. In this guide, you don't want to advertise a distribution and not another, but what you want to offer is a list of various solutions according to the approach to using this system. Some distributions require installation before use, while other live systems can be tested without risk to installed system and often it can be installed.
Testing, the future is stable; only fairly mature packages can be integrated. If so, installation will be much easier. It is recommended to use the "most recent" version. The "Latest" version usually has a few features. . However, you will always refer to the same user configuration files. The captain script allows you to select startup options and configurations from an easy to understand GUI. If it is not in its distribution repository, it can be done.
GNU/Linux has already found many fans and is gaining more and more popularity today. The number of distributions is growing rapidly, so you need to be able to figure out which is the most optimal. And rightly so, because Linux is a free graphical interface that rightfully enjoys the greatest success around the world. Often the user needs to know the version of Linux, for example, to install any programs compiled for certain versions. Their numbers are calculated as "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, such as "Karmic" or "Lucid Lynx".
Omega 3. Just unzip the archive to a folder of your choice. In this case, startup scripts will not be written to the execution path. To start with command line, open a terminal window. Basic download command. Then the team will. There are many possibilities and procedures for their implementation, however, given the many distributions. This can be easily restored in the future. This will mean removing any user configuration settings and - if the folder is deleted "correctly", i.e. not just moved to the trash can - the action cannot be undone.
What is the core really, what are the differences between these cores, why develop them constantly and give them an account? The core is the central link of the system, it is very large, but at the same time it contains an ordered and clear hierarchy of various levels. Its main components are: system calls (SCI), process management (PM), memory management (MM), and virtual system files (VFS), network stack and various device drivers. Finding out 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, it is extremely rare to deal with it, because not everyone will be able to cover all the important and subtle aspects of this software level. Versions differ in interaction with hardware, drivers and speed. And everything 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).
It is also known as "superuser". Here's a real testimonial from a client that should serve as a warning. Perform "normal" activities on the system as root, as the risk of something dangerous being seriously hacked and seriously damaging the system by mixing user data with system data. There are some exceptions to this rule of practice, as will be shown below. . During installation, you are prompted to add at least one regular user to the user database.
You won't be surprised when you are told not to change this setting. This leads to the next recommendation. Consider creating a user to manage tasks and data system administrator. Before proceeding, you need to make some details about the network.
Check version linux user Maybe different ways. For example, there is a "lsb_release" utility that can be used with the -a option. First you need to go to and then type the command. It may not be possible to install it, then the program will have to be downloaded from the repository. Once entered, the screen will show the name of the distribution and its version.
Programs that solve the problem offline
We have already talked about the problem of logging in as a root with a graphical login operator.
Long sessions like long root
When accessing a terminal with administrative privileges for a longer period of time, use the command.The code below is a non-followable example. If you run the code below, you will destroy your system, deleting everything it contains. Notice the other prompt. The real console of your system is the one that you can access using the key combination you already know, as it is also used to access the graphical session. To enable this reuse of the system, several "logical screens" are available. First try this key combination after system boots, you will see on the screen last lines output file generated by this download, and a line with a blinking cursor for Terminal Access.
You can see the Linux version by typing "cat/etc/issue". After that, the following output 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 found out using the given function "uname -r", but if you write -a instead of the last prefix, then all the information on this command will be displayed.
In these cases, you cannot access both regular user. This is one of the reasons why directories are organized this way. The goal is not to say "we are right and you are wrong", but. Show that most of the criticism has already been discussed and therefore there is no need to repeat it. Redirect criticism to what might be the real problem rather than trying to figure out what the problems are. This has led to many options with different focus.
These options are called distributions. Even in this category there is a choice of several dozen options. Some of them are due to small requirements for old computers, some of them are good choice for powerful PCs, where the user appreciates an impressive and intuitive interface.
Also, if it is impossible to log into the system, you can find out the version of Linux by rebooting system block and in the download menu, find all the most necessary information. A similar method serves to identify which distribution is being used.
Information about Linux system is also stored in /etc/lsb-release. Therefore, to open it in the terminal, enter the following command: cat /etc/lsb-release. Also in the Linux GUI system, you can find out the version from the user manual.
Choice operating system and its variants is an extremely important thing. When it comes to food, cars, clothes, and places to stay, we take it for granted. Make an informed decision. In fact, open source systems are very motivating for people to write high quality code, and multiple people review and modify the same source. Leading companies are also involved. There are advanced graphical user interfaces for all common tasks, you can choose the one that best suits your needs.
So, various systems of the Linux family, being quite complex, 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.
