A few different ways to check the linux distribution and release / version
Ever find yourself in need of figuring out the exact linux distro and release number of the system you are on? As usual in Linux – there are several ways to do this!
This is probably my favorite, because its succinct & cross-platform, but in some cases lsb_release may need to be installed. Comes built-in to current Debian releases:
% lsb_release -d Description: Debian GNU/Linux 8.10 (jessie)
This is for Debian & Debian-based systems:
% cat /etc/debian_version 8.10
Here are some more methods:
% hostnamectl Static hostname: brackin-deb-1 Icon name: computer-vm Chassis: vm Machine ID: 48cbccecf9bf47c7a403f21ac21ea1d0 Boot ID: 44eaf92350f2479aa3474b60c419dc15 Virtualization: kvm Operating System: Debian GNU/Linux 8 (jessie) Kernel: Linux 3.16.0-4-amd64
% cat /etc/os-release PRETTY_NAME="Debian GNU/Linux 8 (jessie)" NAME="Debian GNU/Linux" VERSION_ID="8" VERSION="8 (jessie)" ID=debian HOME_URL="http://www.debian.org/" SUPPORT_URL="http://www.debian.org/support" BUG_REPORT_URL="https://bugs.debian.org/"
