Popular UNIX family operating systems :
AIX - AIX (Advanced Interactive eXecutive) is a series of proprietary Unix operating systems developed and sold by IBM. AIX is an open, standards-based operating system that conforms to The Open Group's Single UNIX Specification Version 3. It provides fully integrated support for 32- and 64-bit applications.
BSD/OS - BSD stands for Berkeley Software Distribution. BSD/OS was a proprietary version of the BSD operating system developed by Berkeley Software Design. Historically, BSD has been considered a branch of UNIX—"BSD UNIX", because it shared the initial codebase and design with the original AT&T UNIX operating system.
OpenBSD - The OpenBSD project produces a FREE, multi-platform 4.4BSD-based UNIX-like operating system. In December 1994, NetBSD co-founder Theo de Raadt was asked to resign from his position as a senior developer and member of the NetBSD core team.
NetBSD - NetBSD is a free, fast, secure, and highly portable Unix-like Open Source operating system. It is available for a wide range of platforms, from large-scale servers and powerful desktop systems to handheld and embedded devices. Its clean design and advanced features make it excellent for use in both production and research environments, and the source code is freely available under a business-friendly license. NetBSD is developed and supported by a large and vivid international community.
FreeBSD - FreeBSD is an advanced operating system for modern server, desktop, and embedded computer platforms. It is developed and maintained by a large team of individuals. FreeBSD provides advanced networking, impressive security features, and world class performance and is used by some of the world's busiest web sites and most pervasive embedded networking and storage devices.
HP-UX - HP-UX (Hewlett-Packard UniX) is Hewlett-Packard's proprietary implementation of the Unix operating system, based on UNIX System V (initially System III) and first released in 1984. Recent versions support the HP 9000 series of computer systems, based on the PA-RISC processor architecture, and HP Integrity systems, based on Intel's Itanium architecture.
Tru64 - Tru64 UNIX is a 64-bit UNIX operating system for the Alpha instruction set architecture (ISA), currently owned by Hewlett-Packard (HP). Previously, Tru64 UNIX was a product of Compaq, and before that, Digital Equipment Corporation (DEC), where it was known as Digital UNIX (formerly DEC OSF/1 AXP).
IRIX - IRIX is a computer operating system developed by Silicon Graphics, Inc. (SGI) to run natively on their MIPS architecture workstations and servers. It was based on UNIX System V with BSD extensions. IRIX was the first operating system to include the XFS file system.
Solaris - Solaris is a Unix operating system originally developed by Sun Microsystems. It superseded their earlier SunOS in 1993. Oracle Solaris, as it is now known, has been owned by Oracle Corporation since Oracle's acquisition of Sun in January 2010.
MAC OS - Mac OS is a series of GUI-based operating systems developed by Apple. OS X operating system is the successor to Mac OS 9 and the "classic" Mac OS. It is however a Unix-like operating system, based on the NeXTSTEP operating system and the Mach kernel which Apple acquired after purchasing NeXT Computer - with its CEO Steve Jobs returning to Apple at that time.
unixware - unixware is developed by Santa Cruz Operation. It is implemented as a server not the Desktop system.
