## 操作系统：时间轴和家族树 ##

*本文译自：[Operating Systems: Timeline and Family Tree][Operating Systems_ Timeline and Family Tree]*

摘要：各操作系统出现的时间轴，各操作系统之间的关系、操作系统家族关系，如常见的：Unix、FreeBSD、iOS、Mac OS、OpenBSD、类 Unix、Linux、Android、CentOS、Debian、Fedora、Oracle、Red Hat、SuSE、Ubuntu、CP/M、DOS、VMS、Windows、AmigaOS、RISC、IBM大型机、L4、OSEK等。

### 到目前为止包括大约 850 个操作系统 ###

上次更新时间：2022 年 1 月

在这篇文章中，您将找到操作系统的家谱和时间表。我试图包括所有操作系统，无论多旧或晦涩难懂。当然，一个完整的列表几乎是不可能的，因为没有办法对所有可能存在的微小爱好和嵌入式系统进行编目。

另请注意，我只收录了几个选定的 Linux/BSD/Solaris 发行版（这些发行版是否应该单独算作操作系统是有争议的）。

目前，家谱包括 800 到 900 种不同的操作系统。提示：使用 Ctrl+F（在 Mac 上为 Cmd+F）搜索系统。
