Knowing the Linux version / OS / Kernal details

Hi All,

Greetings for the day 🙂 LIFE IS BEAUTIFUL 🙂

Background :

• Recently got a chance to work on Docker
• So I got the Linux VM from our admin team to play with Docker
• I am connected to Linux VM using SSH (Secure Shell) and I dont have any details about Linux installed, to download docker and install I want to know the which Linux os and version installed
• Since I am new to Linux (as hardcore Microsoft Guy 🙂 ) I need to google how to know the respective Linux OS and Version and hence birth of this article 🙂

After bit googling I found three ways to to get the OS details on Linux

Using cat command – execute following command

cat /etc/os-release

Sample output :

NAME="Linux Server"
VERSION="7.8"
ID="Linux"
ID_LIKE="fedora"
VARIANT="Server"
VARIANT_ID="server"
VERSION_ID="7.8"
PRETTY_NAME="Linux Server 7.8"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:linux:7:8:server"
HOME_URL="https://linux.oracle.com/"

• The cat command is used for
  • To display text file
  • To read text file
  • to create new text file
  • File concatenation
  • To combine text and binary files

Using lbs_release command

$ lsb_release -a

Sample output :

LSB Version:    :core-4.1-amd64:core-4.1-noarch
Distributor ID: LinuxOS
Description:    Linux Server release 7.8
Release:        7.8
Codename:       n/a

Using hostnamectl command

hostnamectl

Sample output :

 Static hostname: 
         Icon name: computer-vm
           Chassis: vm
        Machine ID: 
           Boot ID: 
    Virtualization: vmware
  Operating System: Server 7.8
       CPE OS Name: linux:7:8:server
            Kernel: Linux 4.14.35-1902.302.2.el7uek.x86_64
      Architecture: x86-64
