And remember add in the copyright to that does not come about until much, much later in UNIX's life.  After Judge Green and after the cat was out of the bag, and when AT&T was allowed to be in the computer business.   Pre Judge Green - if you go in the V7 source that Warren has you will see:

[ctcole-mac09:ResearchEditions/v7_SeventhEdition/V7_FileTree] ctcole% cat bin/true
[ctcole-mac09:ResearchEditions/v7_SeventhEdition/V7_FileTree] ctcole% cat bin/false
exit 1
[ctcole-mac09:ResearchEditions/v7_SeventhEdition/V7_FileTree] ctcole% ll bin/{false,true}
-rwxrwxr-x  1 ctcole  staff  - 7 Jan 10  1979 bin/false
-rwxrwxr-x  1 ctcole  staff  - 0 Jan 10  1979 bin/true

It's been a long time since I looked at the AT&T source, but I recall that
the version number was pushing 2 digits. It's hard to get it "wrong" on the first try
(although I could possibly do it). More likely, the version numbers reflected
changes to the licensing wording. -- jpl

No one said that "open source" was created at that point.  The perl,
BSD, FSF's emacs, gcc, and other software published under the GPL all
predated the definition of the **term** "Open Source".

However, I strongly contest the claim that Unix was "Open Source".
Unix was the UNPUBLISHED TRADE SECRET of AT&T, and students exposed to
Unix source code became contaminated with AT&T's "methods and
concepts" clause.  So they couldn't even *reimplement* Unix without
potentially getting sued by AT&T.

I always thought the implementation of /bin/true, which was a shell
script where the license statement proclaiming AT&T's copyright was
longer than the "exit 0" line, was both incredibly funny, and
incredibly sad.
