Plan 9 – a distributed operating system, originally developed by the Computing Sciences Research Center at Bell Labs between the mid-1980s and 2002. Its original designers and authors were Ken Thompson, Rob Pike, Dave Presotto, and Phil Winterbottom.
Plan 9 demonstrates a new and often cleaner way to solve most systems problems. The system as a whole is likely to feel tantalizingly familiar to Unix users but at the same time quite foreign.
Plan 9 is an operating system kernel but also a collection of accompanying software. The bulk of the software is predominantly new, written for Plan 9 rather than ported from Unix or other systems. The window system, compilers, file server, and network services are all freshly written for Plan 9. Although classic Unix programs like dc, ed, and troff have been brought along, they are often in an updated form.
Starting with the release of Fourth edition on April 2002, the full source code of Plan 9 from Bell Labs was freely available under Lucent Public License 1.02.
