Overview

A small utility script to detect *nix operating system. It works in shell and aims to correctly recognise distributions like

• Alpine
• Debian
• Ubuntu

and more.

Quick Start

This utility can be installed locally in the user's home directory

• as a standalone script

curl -fsLS https://raw.githubusercontent.com/make-ops-tools/detect-operating-system/main/scripts/detect-operating-system.sh > ~/bin/detect-operating-system
chmod +x ~/bin/detect-operating-system

• along with the project files

sh -c "$(curl -fsLS https://raw.githubusercontent.com/make-ops-tools/detect-operating-system/main/install.sh)"

Alternatively, for a convenience, a shorten and memorable version of the above URL can be used which is tiny.one/detect-os.

A quick test can be done using the make targets provided

cd ~/.make-ops-tools/detect-operating-system
make detect-os
make test
