'''xv6'''是以[[ANSI C]]重新編寫的[[Version 6 Unix|Unix第六版]]現代實作版本，適用於[[多处理器]][[x86]]或[[RISC-V]]系統。xv6是[[麻省理工学院]]於 2006 年為了教學用途開發的系統，在該校的作業系統工程（6.828）課程中使用。
== 目的 ==
[[麻省理工学院]] 原先在作業系統課程中使用 [[Version 6 Unix|V6]]，但由于[[PDP-11]]机器已不再普及，且該系統使用過時的 pre-ANSI C 開發，學校決定創造 xv6 作為替代方案。
相較於 [[Linux]] 或 [[BSD]]，xv6 非常简单，適合在一學期的課程中教授，但仍然包含 [[Unix]] 的重要概念和组织<ref name="6.828">{{Cite web|url=https://pdos.csail.mit.edu/6.828/xv6|title=Xv6, a simple Unix-like teaching operating system|accessdate=2014-09-22|archive-date=2015-08-23|archive-url=https://web.archive.org/web/20150823023719/http://pdos.csail.mit.edu/6.828/xv6/}}</ref>。

== 內建-{zh-tw:文件;zh-cn:文档}- ==
xv6 [[Makefile]]的一个特性是能够以可读的格式生成整个源代码清单的[[PDF]]文档。整个打印输出只有99页，包括交叉引用<ref>{{Cite web|url=https://pdos.csail.mit.edu/6.828/2018/xv6/xv6-rev11.pdf|title=xv6 source listing|accessdate=2018-01-10|format=pdf|archive-date=2021-12-09|archive-url=https://web.archive.org/web/20211209205722/https://pdos.csail.mit.edu/6.828/2018/xv6/xv6-rev11.pdf}}</ref>。这让人想起原始的V6源代码，该代码在《Lions' Commentary on UNIX 6th Edition, with Source Code》一书中以类似的形式发布。

== 教学使用 ==
xv6已被用于许多著名大学的操作系统课程，包括：
