Research Unix versions are often referred to by the edition of the manual that describes them, [1] because early versions and the last few were never officially released outside of Bell Labs, and grew organically. So, the first Research Unix would be the First Edition, and the last the Tenth Edition.
Unix versions from Bell Labs were designated by the edition of the user's manual with which they were accompanied. Released in 1979, the Seventh Edition was preceded by Sixth Edition, which was the first version licensed to commercial users. [1]
Development expanded, adding the concept of pipes, which led to the development of a more modular code base, and quicker development cycles. Version 5, and especially Version 6, led to a plethora of different Unix versions both inside and outside Bell Labs, including PWB/UNIX and the first commercial Unix, IS/1. Unix still only ran on DEC ...
Unix (/ ˈ j uː n ɪ k s / ⓘ, YOO-niks; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 [1] at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. [4]

Plan 9 from Bell Labs is a distributed operating system which originated from the Computing Science Research Center (CSRC) at Bell Labs in the mid-1980s and built on UNIX concepts first developed there in the late 1960s. Since 2000, Plan 9 has been free and open-source. The final official release was in early 2015.
Columbus UNIX, or CB UNIX, is a discontinued variant of the UNIX operating system used internally at Bell Labs [1] for administrative databases and transaction processing. [2] It was developed at the Columbus, Ohio branch, based on V6, V7 and PWB Unix. [3] It was little-known outside the company.
PWB/UNIX started with Research Unix 4th Edition in mid-October 1973, and was frequently updated over the next few years, as the PWB department tracked Research Unix changes and added a few features. The PWB shell was released in mid-1975 [ 4 ] and remained available through Version 6 Unix -based PWB/UNIX. [ 5 ]
