Just a quick question. Was the `dc' command
introduced with one of the
BSD releases or did it exist in an earlier version of Unix like the 6th or
7th Edition?
It appears in the First Edition manual, and according to A Quarter
Century of Unix, it's even older than that.

Hmmm... did the permissions on files have the same meaning back in 1973 as
they do now? Group and "other" writeable system binaries? Tsk tsk tsk.
Well I suppose just because someone has written the Unix operating system,
it doesn't necessarily mean that they're a very good Unix sysadmin.

On the other hand, people actually trusted each other, because you
all worked with each other, and it was common for someone to write a
utility and stick it on the system. Hint: /usr wasn't called that for
no reason...

In article by Greg Lehey:
The binary is an 0405 a.out file. I'm told by Norman Wilson, who has
paper copies of the 2nd & 3rd Edition manuals, that 0405 binaries didn't
exist in 2nd & 3rd Edition.
I also believe that the files in the s2.tar tarball sent in by Dennis
are a whole year off, and so the date above should be Apr 14, 1972.
That dates the file just before the release of 2nd Edition.
I really need to sit down & outline my reasons for believing that the
dates are a year out. I'll do so soon & email it here!
Cheers all,
Warren
