Despite its humble name, it provides far more than just your hostname $ hostnamectl

If it's not already installed, you can install it from your software repository. The hostnamectl command is available on most modern Linux distributions. The screenfetch and neofetch commands give a verbose overview of your system, with details about your kernel, architecture, available RAM, CPU speed and core count, desktop version, and so on. There are, however, additional tools that can provide you a report about your system. The uname and /etc/os-release commands are the most common methods for getting the version of Linux you're running and are available by default on any Linux system you run. More information about the os-release file can be found by running man os-release. CentOS is designed to be a near clone of RHEL, so it is more compatible with its LIKE than some entries that might be found in the ID_LIKE field, but checking for answers about a "like" distribution is always a good idea if you cannot find the information you are seeking for the running distribution. The ID_LIKE line is very helpful if you are working with a distribution that is based on another distribution and need to find instructions to solve a problem.ĬentOS's os-release file makes it clear that it is like RHEL, so documentation and questions and answers in various forums about RHEL should (in most cases) apply to CentOS. For example, Red Hat Enterprise Linux's os-release file includes an ID_LIKE line stating that RHEL is like Fedora, and CentOS's os-release file states that CentOS is like RHEL and Fedora. Sometimes it is useful to know if a distribution is like another, so the os-release file can contain an ID_LIKE line that identifies distributions the running distribution is based on or is similar to. If we ran the same command on Fedora 28 Server Edition, the contents of the os-release file would reflect that on the VARIANT and VARIANT_ID lines.
PRETTY_NAME="Fedora 28 (Workstation Edition)"ĬPE_NAME="cpe:/o:fedoraproject:fedora:28"Īs the example above shows, Fedora's os-release file provides the name of the distribution and the version, but it also identifies the installed variant (the "Workstation Edition").
On Fedora 28, the output looks like this: NAME=Fedora To view the contents of the os-release file, run the following command: cat /etc/os-release The os-release file in some distributions contains more details than in others, but any distribution that includes an os-release file should provide a distribution's name and version. This file provides information about a distribution including, but not limited to, the name of the distribution and its version number. There are several ways to figure out what distribution is running on a system, but the quickest way is the check the contents of the /etc/os-release file. More information about the uname command can be found by running man uname. In this case, the kernel is Linux version 4.16.86_64 running on an x86_64 system. This gives you (in order): the kernel name, the version of the kernel, and the type of hardware the kernel is running on.
To find out what version of the Linux kernel is running, run the following command: uname -srmĪlternatively, the command can be run by using the longer, more descriptive, versions of the various flags: uname -kernel-name -kernel-release -machineĮither way, the output should look similar to the following: Linux 4.16.86_64 x86_64 The following will help you find out what version of the Linux kernel and/or what Linux distribution is running on a system. For example, knowing the installed kernel version might help diagnose an issue with proprietary drivers, and identifying what distribution is running will help you quickly figure out if you should be using apt, dnf, yum, or some other command to install packages.
