这是 Unix V4 吗？

我仔细研究了 Unix V4 磁带，它看起来和 Unix V5 非常相似。日期是 1974 年 6 月，其中包含各种工具，例如 diff，这些工具在 Unix V5 手册中，但不在 V4 手册中。我怀疑这张磁带是在 Unix V5 发布前不久制作的，根据 https://en.wikipedia.org/wiki/Research_Unix，Unix V5 也是在 1974 年 6 月发布的，而 Unix V4 是 1973 年 11 月发布的。我不确定我们是否真的比 12 月之前拥有更多东西。

I've been looking closely at the Unix V4 tape and it looks awfully similar to Unix V5. The dates are from June 1974 and it includes various tools such as diff which are in the Unix V5 manual but not in the V4 manual. I suspect that this tape was made shortly before the Unix V5 release which according to https://en.wikipedia.org/wiki/Research_Unix was also released in June 1974 whereas Unix V4 was from November 1973. I'm not convinced that we really have much more than we did before December.<p>Gus Fernandez
