How To Find Out My Linux Distribution Name and Version

How do I find out what version of Linux distribution I am using from the shell (bash) prompt? How can I tell my Linux distribution name and version?

You can use any one of the following method to find out your Linux distribution and name:

a] /etc/*-release file.

b] lsb_release command

c] /proc/version file.

d] hostnamectl command

Method 1. Use /etc/*-release file to display Linux distro version

To find out what version of Linux (distro) you are running, enter the following cat command at the shell prompt:
$ cat /etc/*-release
Sample output from my RHEL v5.x server:

Red Hat Enterprise Linux Server release 5 (Tikanga)

Sample outputs from my Ubuntu Linux v7.10 server:


Method 2. Use lsb_release command To find out Linux distribution name and version

The lsb_release command displays certain LSB (Linux Standard Base) and distribution-specific information. Type the following command:
$ lsb_release -a
Sample outputs:

No LSB modules are available.
Distributor ID:	Debian
Description:	Debian GNU/Linux 6.0.1 (squeeze)
Release:	6.0.1
Codename:	squeeze

Method 3. Use hostnamectl to find out my Linux distribution name and version

For GNU systemd based distro this is the best option:
$ hostnamectl

What version of Linux am I running?

How do I find out My Linux kernel version?

Type the following uname command:
$ uname -a
$ uname -mrs
Sample outputs:

Linux 2.6.32-5-amd64 x86_64

Linux 2.6.32-5-amd64 x86_64


  1. Linux – Kernel name
  2. 2.6.32-5-amd64 – Kernel version number
  3. x86_64 – Machine hardware name (64 bit)

Here is output from my SUSE Enterprise Linux server:

Say hello to /proc/version

Type the following command to see kernel version and gcc version used to build the same:
$ cat /proc/version
Sample outputs:

Linux version 3.2.0-0.bpo.1-amd64 (Debian 3.2.4-1~bpo60+1) ([email protected]) (gcc version 4.4.5 (Debian 4.4.5-8) ) #1 SMP Sat Feb 11 08:41:32 UTC 2012

Another outputs from my CentOS 7 box:
