Linux:- Get Distro Name via lsb_release ( CentOS )

Background

Last evening, a family member asked me whether it is Ubuntu we are running on one of our Linux boxes.

I said I think it is CentOS.

But, I will confirm.

lsb_release

lsb_release to the rescue.

 

Error

Command – lsb_release

Installation

Where can I get lsb_release?

There are a couple of pathways we can explore to determine which registered repo and package provides a command.

Options

  1. yum
    • what-provides
  2. dnf
    • dnf provides

Command

yum

yum – what-provides
Outline

We can use yum’s whatprovides option to inquire as to which repository and package provides a file or library.

Syntax
yum whatprovides [file]
Sample
yum whatprovides lsb_release -y
Output – Text

>yum whatprovides lsb_release -y
