[[Category:Operating Systems]]'''Plan 9''' is an operating system from AT&T's [[Bell Labs]]. It was created by the same group which developed [[UNIX]]. Their intent was to design a new operating system that incorporated new developments since UNIX's creation, such as networking and [[GUI|graphical user interfaces]].
==Programming==
The kernel is written primarily in [[C]], with a minimum of assembly for greater portability. The user-level applications are mostly in
Plan 9 is designed in such a way that the "everything is a file" metaphor extends very well. Network connections can be accessed through /net/tcp, for example, and mouse events are written in plain text to /dev/mouse. Every [[process]] has a separate namespace.
Available languages include:

*rc
*[[sh]] ([[POSIX]] emulation)
*[[Perl]]
*[[Python]]
*[[Haskell]]
*[[Assembly]] (all platforms share the same syntax; less machine-specific)
==GUI==
The creators of Plan 9 took the opportunity to build graphics capabilities into the system from the ground up, unlike UNIX. The most frequently-used "window manager" for Plan 9 is called rio, as seen in [http://csplan9.rit.edu/users/john/rosettacode.png this image].
