You can find out the current kernel version by issuing the command
uname -r
You can find the name of the distro and it's version number by running
cat /etc/*release
or**
cat /etc/*version
**If the first one doesn't work, try the second, since not all distros keep theirs in the same place.
Using the uname command, you can identify what kernel version you're using. as shown below.
uname -arv
uname -r
A Linux distribution, known as distro or flavor, is an operating system that uses the Linux Kernel. I think the most common one is Ubuntu.
Kernel, but I guess when you will learn, you will have to switch (Ubuntu for programmers and gamers and Kali Linux for penetration testers and hackers)
Linux is an operating system kernel. By itself, it can do very little. It needs to be combined with an interface and applications in order to be useful. When you take the kernel and add the parts to create a working system, you create what is called a "Linux distrbution", or "distro." Fedora is an example of a Linux distro. In summary, Linux is a kernel, and Fedora is a full operating system.
there is no "linux operating system". linux is merely a kernel that operating systems can be built upon, of which there are dozens if not hundreds
These are separate and unrelated tasks. To check the version of the running kernel in Linux, use the command uname -r. To upgrade the kernel, either use your distro's package manager (if any) to update the system, or download and compile the Linux kernel source.
"Types" of Linux are Called Linux Distributions. Linux by itself is only a kernel, you need more than that for a full system, to get this, distro's were develpoed to include all of this to make a Linux system easier to install. Popular Distro's Are Ubuntu, Debian, Fedora, RHEL, Linux Mint, Arch Linux, OpenSUSE, etc, you can find more at distrowatch
As 'Linux' is actually the Linux Kernel and a bunch of other tools packaged together as a distro, this will depend on the distro you use. For example, Red Hat Linux uses a file called ks.cfg (known as kickstart) which contains information for it's installer system called Anaconda.
There is no "Linux 4" or "Linux 9." I'm not sure where people get these numbers from. They could be reading the version numbers of a particular distro (such as Red Hat Enterprise Linux 4 or SUSE Linux Enterprise Server 9). However, the Linux kernel is developed centrally and then subsequently used by all of the distribution vendors. The current stable version of the Linux kernel is 2.6.30; the 2.6 kernel line is expected to continue indefinitely.
Any distribution using a kernel newer than 2.6.8 (aka any distro except the Small Linux that you'll find in 2009).
The Linux kernel supports up to the latest Intel and AMD processors, as well as some other architectures. As such, most programs should run about the same on all of them.
Linux is the kernel.
Any reasonably modern Linux kernel (2.4 and higher) and any distro using such a kernel should be able to boot from and access the entirety of a 500 GB hard drive. Examples of modern distros include Ubuntu. OpenSUSE, Debian 5, PCLinuxOS, and Linux Mint.
