Determine the Linux Distribution
Determine the Linux DistributionThere 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
