Unix and Linux Distributions Lists

The family of Unix-based operating systems is richer than just Linux

Unix isn't a single operating system. It offers many modern variants, also referred to as flavors, types, distributions, or implementations. These variants branch from its origins in early 1970s mainframe computing. Although based on a core set of Unix commands, different distributions have unique commands and features and are designed to work with different types of hardware.

Main Branches of Unix

Contemporary Unix implementations are either open-source (that is, free to download, use, or modify) or closed source (that is, proprietary binary files not subject to user modification). These are the main Unix variants:

  • Minix: A Unix-like open-source project, rarely used by home users.
  • Linux: An open-source initiative to bring a Unix-like environment to both the desktop and server space. Linux is popular with home computer enthusiasts.
  • Mac OS X: The Apple desktop operating system.
  • BSD (FreeBSD, DragonflyBSD, NetBSD, OpenBSD): A branch from the earliest Unix specs, following the design principles of the Berkeley Software Distribution.
  • AIX: A series of Unix-based operating environments developed by IBM for its servers.
  • Solaris: A proprietary server operating system based on Unix and developed by Sun Microsystems.
  • OpenSolaris: An open-source variant of Solaris.
  • HP-UX: A series of Unix-based operating environments developed by HP for its servers.
  • OpenServer: Based on FreeBSD and a closed source operating system. It is now owned by Xinuos. Previously known as SCO UNIX, it was developed by Santa Cruz Operation. SCO acquired the rights to the UnixWare operating system, portions of which became part of OpenServer.

No one knows exactly how many Unix flavors are there, but it is safe to say that if including all those that are obscure and obsolete, the number of Unix flavors is at least in the hundreds.

Common Consumer Distributions

Over the years, different Linux flavors have enjoyed more or less popularity, but several stand out as being among the most commonly deployed on desktop computers. Some of the most commonly accessed distributions include:

  • Mint: A version of Ubuntu with additional software drivers and minor customizations.
  • Debian: A project that bills itself as a universal operating system. It has a significant market share and a robust base of applications.
  • Manjaro: Based on the Arch Linux project and supports extensive configurations.
  • Ubuntu: A significant player in the Linux market. Ubuntu offers an easy-to-use distribution that's beautifully designed and accessible despite language and disability barriers.
  • Antergos: Based on the Arch Linux project. This distribution offers a custom installer program.
  • OpenSUSE: A long-running German distribution that's the community version of the SUSE Linux commercial distribution.
  • Fedora: A community project based on Red Hat Linux (an operating system that was discontinued in 2004).
  • Solus: A built-from-scratch distribution from Ireland with a custom desktop environment called Budgie that looks like the old GNOME 2 desktop (GNOME is the default desktop environment on many major Linux distributions).
  • Zorin: A distribution intended to mimic the look-and-feel of Windows to help new Linux users transition away from the Microsoft Windows operating system.
  • Elementary: Based on Ubuntu and uses a custom desktop environment called Parthenon that resembles, in some ways, Mac OS.

You might have a Linux device in the palm of your hand. The Android operating environment for smartphones and tablets is based on Linux and can be considered a type of Linux distribution in its own right.
