How to check the lsb_release of your redhat based Linux distros

To check the lsb_release of your RedHat based Linux Distros
LSB stands for Linux Standard Base which is an effort to standardize the structure of Linux related operating systems. It increases compatibility among systems that use different versions  of Unix and to make them more compatible with non-Unix systems as well. The main reason is due to the difference between various Unix flavors which have caused problems in systems and networks where more than one flavour was found. So this standardization would enlarge the customer base and their satisfaction and decrease the cost of overcoming incompatibility issues.

Installation
In Debian based distributions the lsb_release comes by default and you can verify by using the following command directly from the terminal

linuxhelp ~ # lsb_release -a
No LSB modules are available.
Distributor ID:    LinuxMint
Description:    Linux Mint 18.3 Sylvia
Release:    18.3
Codename:    sylvia

But in RedHat distributions, if you run the following command you will face the following output

[root@linuxhelp ~]# lsb_release
bash: lsb_release: command not found...

Let’ s see How to install lsb release before that we should find which package provides lsb release.

[root@linuxhelp ~]# yum provides */lsb_release
