Unix 程式碼演進的記錄

GitHub 上的「dspinellis/unix-history-repo」專案放進了 Unix 程式碼從 1970 年演進到 2016 年的記錄:

The history and evolution of the Unix operating system is made available as a revision management repository, covering the period from its inception in 1970 as a 2.5 thousand line kernel and 26 commands, to 2016 as a widely-used 27 million line system.

主要的目的是讓研究人員可以直接分析,減少重複的工作:

The project aims to put in the repository as much metadata as possible, allowing the automated analysis of Unix history.

後面的分支主要是以 FreeBSD 為主:(在列表的部份也可以看到)

It has been created by synthesizing with custom software 24 snapshots of systems developed at Bell Labs, the University of California at Berkeley, and the 386BSD team, two legacy repositories, and the modern repository of the open source FreeBSD system.

整個 repository 頗壯觀的 XD
