Subject: [TUHS] Origin year of BSD csh?

1BSD did not contain csh, and was officially released March 9 1978. It
contained something called "a shell" which appears to be a predecessor
to csh, but was still compiled as sh. The README on 1BSD from Bill Joy
states:
Wed Oct 19, 1977
This directory contains the source for a shell.
It requires floating point to do the time command which is built-in
so you will have to cc it -f on machines without floating point.
It also requires a version 7 C compiler.
Accurate documentation is in the file "sh.6" to be nroffed with
/usr/man/man0/naa and a new "version 7" nroff.
This shell requires the "htmp" data base also used by the editor "ex".
If you do not set it up so that the "sethome" command is done by "login"
then you should use the old "osethome" routine in ../s6 rather than
"sethome"
and reenable the execl of this sethome in the file "sh.c" (with the
correct
pathname).
2BSD did include csh and was first officially released May 1979. I'm
sure there were informal advance copies of csh sent out sooner. I recall
csh already being on the UCB systems when I arrived in September of 1978.
I brought csh with me to Bell Labs in the summer of 1979. The folks at
Bell Labs recoiled in horror: they had just gone through a painful
conversion from the Mashey shell to the Bourne shell, and would never
consider another conversion. csh was (mostly) upward compatible with
the Mashey shell, unlike the Bourne shell. (This was in the Bell Labs
Computer Center, where I was a summer employee, not Research or the PWB
group, which I'm sure felt the same way.)
