How to Get System Information With uname Command in Linux – Guide
The uname command is the first choice when it comes to extracting system information, whether you are a developer working on a script that requires kernel information or an ordinary user curious about your operating system. Although uname is reasonably simple to use, the command output can seem sophisticated to beginners at first. This post will show you how to use uname to print critical system-related information on Linux to make things easier for you.
What is the uname command?
As mentioned above, uname is a program on Linux and other Unix-based operating systems that produces basic operating system and kernel information in a clean format. Although uname stands for Unix Name, the command has also been implemented on several other operating systems. The ver command is the Windows command prompt equivalent to uname. The basic syntax of the command is: uname options … Where options are flags you can specify in the command. Typing uname into the terminal generates the kernel name. uname Exit: Linux But that is not all. Using the -a flag with uname provides complete information about the kernel and operating system. The -a flag means All. uname -a
splitting the output
As you can see, there are several fields displayed in the output. Let’s talk one by one. Linux kali 5.10.0-kali7-amd64 #1 SMP Debian 5.10.28-1kali1 (2021-04-12) x86_64 GNU / Linux Uname also displays various other fields, such as the processor type and system hardware platform. The reason it did not generate these specific fields is that the information corresponding to these fields is unknown to the command. So instead of displaying unknown, the developers chose to strip these fields out of the output.
Display individual information using uname
In addition to the -a flag, there are other options you can use with uname. Each of the additional flags is mapped to a single field and can be used to display that specific field in the output. For example, if you only want the operating system name, use the -o flag: name it Exit: GNU / Linux Likewise, you can use the following eight options with uname to generate individual fields. To get command-line help and display the version information associated with uname, use the –help and –version flags respectively. uname –help Nothing is hidden in Linux. Unlike Windows and other operating systems, the source code for Linux is open source and freely distributed. This means that anyone can access the Linux kernel code and modify it to suit their needs. However, this requires experience and skills, as understanding the kernel source code is not a piece of cake. Someone who is just starting out with the C programming language will have to gain extensive knowledge of development before starting to develop the Linux kernel.
