Distribution (Distro)

Also known as: distro, Linux distribution

A complete operating system built around the Linux kernel, bundling a package manager, userland tools, defaults, and a release model.

What Is a Linux Distribution (Distro)?

A distribution takes the Linux kernel and packages it with everything needed for a usable system: an init system, a shell, core utilities, a package manager, an installer, and usually a desktop environment. Ubuntu, Fedora, Debian, Arch, and openSUSE are all distributions.

Distros differ mostly in package format (.deb, .rpm, Arch packages), release cadence (fixed or rolling), default software, and philosophy. Two distros can run the exact same kernel and still feel completely different to use.

Example

cat /etc/os-release
