Looking to check what Linux Operating System you’re using or the Linux kernel version?<\/p>\n

Linux represents a collection of open-source operating systems built around the Linux kernel<\/strong>. These operating systems are known as Linux Distributions, and some of the most popular ones are Debian, Ubuntu, Fedora, CentOS, Arch Linux and OpenSUSE.<\/p>\n

Whether you’ve just spun up a server, or simply forgotten your distro or kernel, these things are good to keep in mind for potential software compatibility issues or security patches.<\/p>\n\n

Check Linux Distribution Name, Version & Kernel<\/h2>\n

To find the Linux operating system’s name, version or kernel:<\/p>\n

    \n
  1. Open up a terminal (on desktop) or log in via SSH (on a remote server)<\/li>\n
  2. Run any of the following commands to check the Linux OS version details:\n
    cat \/etc\/os-release\ncat \/etc\/issue\nlsb_release -a\nhostnamectl<\/pre>\n<\/li>\n<\/ol>\n
      \n
    1. To check the Linux Kernel version, run one of the following commands:\n
      cat \/proc\/version\nuname -a<\/pre>\n<\/li>\n<\/ol>\n
      Let’s explore each of the commands a little more in depth.<\/p>\n
      Check Linux OS Version Using “cat \/etc\/os-release”<\/h2>\n
      A reliable way to check your Linux OS name and version is checking the contents of the \/etc\/os-release<\/code> file.<\/p>\n
      This command works on multiple distributions. In this guide we’re testing it on CentOS, Debian and Linux Mint (which is based on Ubuntu).<\/p>\n
      As you’ll see, the other commands may not work on expected on every distro.<\/p>\n
      Let’s check the output of this command on the distros mentioned above:<\/p>\n
      $ cat \/etc\/os-release<\/code><\/pre>\n
      CentOS<\/strong><\/p>\n
      NAME=\"CentOS Linux\"\nVERSION=\"7 (Core)\"\nID=\"centos\"\nID_LIKE=\"rhel fedora\"\nVERSION_ID=\"7\"\nPRETTY_NAME=\"CentOS Linux 7 (Core)\"\nANSI_COLOR=\"0;31\"\nCPE_NAME=\"cpe:\/o:centos:centos:7\"\nHOME_URL=\"https:\/\/www.centos.org\/\"\nBUG_REPORT_URL=\"https:\/\/bugs.centos.org\/\"\n\nCENTOS_MANTISBT_PROJECT=\"CentOS-7\"\nCENTOS_MANTISBT_PROJECT_VERSION=\"7\"\nREDHAT_SUPPORT_PRODUCT=\"centos\"\nREDHAT_SUPPORT_PRODUCT_VERSION=\"7\"<\/code><\/pre>\n
      Debian<\/strong><\/p>\n
      PRETTY_NAME=\"Debian GNU\/Linux 9 (stretch)\"\nNAME=\"Debian GNU\/Linux\"\nVERSION_ID=\"9\"\nVERSION=\"9 (stretch)\"\nID=debian\nHOME_URL=\"https:\/\/www.debian.org\/\"\nSUPPORT_URL=\"https:\/\/www.debian.org\/support\"\nBUG_REPORT_URL=\"https:\/\/bugs.debian.org\/\"\n<\/code><\/pre>\n
      Linux Mint<\/strong><\/p>\n
      NAME=\"Linux Mint\"\nVERSION=\"19 (Tara)\"\nID=linuxmint\nID_LIKE=ubuntu\nPRETTY_NAME=\"Linux Mint 19\"\nVERSION_ID=\"19\"\nHOME_URL=\"https:\/\/www.linuxmint.com\/\"\nSUPPORT_URL=\"https:\/\/forums.ubuntu.com\/\"\nBUG_REPORT_URL=\"http:\/\/linuxmint-troubleshooting-guide.readthedocs.io\/en\/latest\/\"\nPRIVACY_POLICY_URL=\"https:\/\/www.linuxmint.com\/\"\nVERSION_CODENAME=tara\nUBUNTU_CODENAME=bionic<\/code><\/pre>\n
      Check Linux OS Version Using “cat \/etc\/issue”<\/h2>\n
      Again, we’ll use the cat<\/code> command, to check the contents of a file. In this case, we’re checking the contents of the \/etc\/issue<\/code> file, which contains system identification text:<\/p>\n
      CentOS<\/strong><\/p>\n
      \\S\nKernel \\r on an \\m<\/code><\/pre>\n
      Debian<\/strong><\/p>\n
      Debian GNU\/Linux 9 \\n \\l<\/code><\/pre>\n
      Linux Mint<\/strong><\/p>\n
      Linux Mint 19 Tara \\n \\l<\/code><\/pre>\n
      Check Linux OS Version Using the “lsb_release” Utility<\/h2>\n
      lsb_release<\/code> is a utility that displays Linux Standard Base information about the Linux distro. Although it is useful for easily displaying version information in a straightforward manner, it’s not always installed by default.<\/p>\n
      Let’s see for ourselves:<\/p>\n
      $ lsb_release -a<\/code><\/pre>\n
      CentOS<\/strong><\/p>\n
      -bash: lsb_release: command not found<\/code><\/pre>\n
      Debian<\/strong><\/p>\n
      No LSB modules are available.\nDistributor ID:\tDebian\nDescription:\tDebian GNU\/Linux 9.4 (stretch)\nRelease:\t9.4\nCodename:\tstretch<\/code><\/pre>\n
      Linux Mint<\/strong><\/p>\n
      No LSB modules are available.\nDistributor ID:\tLinuxMint\nDescription:\tLinux Mint 19 Tara\nRelease:\t19\nCodename:\ttara<\/code><\/pre>\n
      Check Linux OS Version Using “hostnamectl”<\/h2>\n
      hostnamectl<\/code> is a command that lets you display the hostname of the machine, but you can also use it to check a few more details, among them being your OS version and kernel:<\/p>\n
      $ hostnamectl<\/code><\/pre>\n
      CentOS<\/strong><\/p>\n
         Static hostname: panel.dracula.host\n         Icon name: computer-vm\n           Chassis: vm\n        Machine ID: 96820b9851c24560b5f942f2496b9aeb\n           Boot ID: deed538f7ff243a1b4c6d21fe6c0cf5e\n    Virtualization: kvm\n  Operating System: CentOS Linux 7 (Core)\n       CPE OS Name: cpe:\/o:centos:centos:7\n            Kernel: Linux 3.10.0-957.1.3.el7.x86_64\n      Architecture: x86-64<\/code><\/pre>\n
      Debian<\/strong><\/p>\n
         Static hostname: dracula.host\n         Icon name: computer-vm\n           Chassis: vm\n        Machine ID: c692d2988d47468fa27dd7eae4b96e86\n           Boot ID: 6ec9d3271bab4a31a76e38921510339a\n    Virtualization: kvm\n  Operating System: Debian GNU\/Linux 9 (stretch)\n            Kernel: Linux 4.9.0-4-amd64\n      Architecture: x86-64<\/code><\/pre>\n
      Linux Mint<\/strong><\/p>\n
         Static hostname: dracula.prime\n         Icon name: computer-laptop\n           Chassis: laptop\n        Machine ID: ef635a010d284bc38d762d2b9f0e65ac\n           Boot ID: d2614bc3bd62439088eb7ce519b1923e\n  Operating System: Linux Mint 19\n            Kernel: Linux 4.15.0-43-generic\n      Architecture: x86-64<\/code><\/pre>\n
      Check Linux Kernel Using “cat \/proc\/version”<\/h2>\n
      To check our Linux kernel version, we can use the cat<\/code> command to check the contents of the \/proc\/version<\/code> file:<\/p>\n
      $ cat \/proc\/version<\/code><\/pre>\n
      CentOS<\/strong><\/p>\n
      Linux version 3.10.0-957.1.3.el7.x86_64 (mockbuild@kbuilder.bsys.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC) ) #1 SMP Thu Nov 29 14:49:43 UTC 2018<\/code><\/pre>\n
      Debian<\/strong><\/p>\n
      Linux version 4.9.0-4-amd64 (debian-kernel@lists.debian.org) (gcc version 6.3.0 20170516 (Debian 6.3.0-18) ) #1 SMP Debian 4.9.65-3+deb9u1 (2017-12-23)<\/code><\/pre>\n
      Linux Mint<\/strong><\/p>\n
      Linux version 4.15.0-43-generic (buildd@lgw01-amd64-001) (gcc version 7.3.0 (Ubuntu 7.3.0-16ubuntu3)) #46-Ubuntu SMP Thu Dec 6 14:45:28 UTC 2018<\/code><\/pre>\n
      Check Linux Kernel Using “uname”<\/h2>\n
      Lastly, we can check our Linux kernel using the uname<\/code> utility, which is short for unix name<\/strong>.<\/p>\n
      With it, you can check the name, version, kernel and other details about the current machine and operating system.<\/p>\n
      To see all the options, just run:<\/p>\n
      $ uname --help<\/code><\/pre>\n
      Output:<\/p>\n
      Usage: uname [OPTION]...\nPrint certain system information.  With no OPTION, same as -s.\n\n  -a, --all                print all information, in the following order,\n                             except omit -p and -i if unknown:\n  -s, --kernel-name        print the kernel name\n  -n, --nodename           print the network node hostname\n  -r, --kernel-release     print the kernel release\n  -v, --kernel-version     print the kernel version\n  -m, --machine            print the machine hardware name\n  -p, --processor          print the processor type (non-portable)\n  -i, --hardware-platform  print the hardware platform (non-portable)\n  -o, --operating-system   print the operating system\n      --help     display this help and exit\n      --version  output version information and exit\n...<\/code><\/pre>\n
      We’ll just use it to check the Linux kernel, in this guide:<\/p>\n
      $ uname -r<\/code><\/pre>\n
      CentOS<\/strong><\/p>\n
      3.10.0-957.1.3.el7.x86_64<\/code><\/pre>\n
      Debian<\/strong><\/p>\n
      4.9.0-4-amd64<\/code><\/pre>\n
      Linux Mint<\/strong><\/p>\n
      4.15.0-43-generic<\/code><\/pre>\n
      Conclusion<\/h2>\n
      In this guide we’ve explored several ways to check our Linux OS name, version, kernel, and other details.<\/p>\n
