Determine the Linux Distribution

Determine the Linux Distribution

There are chances that you have to develop scripts which need to do different things for the individual Linux distributions and their major and minor version. The file /etc/os-release is the place to go.

Execute the command:

source /etc/os-release

in your bash script and you will have the variables set which matter.

Here is a collection of the various /etc/os-release flavors I'm working with
