It was in V6, and probably before that; it's truly ancient.

​Yep - you see vestiges in ​
v0 - Dennis used an rc file call the parts of the B compiler.    In V1's
man page, it's listed as a bug that
​ calling the B compiler via that script
should probably be a command.
​  Having exec call the shell if the file is executable and not a 4xx magic
number has not yet appeared, but its not that far off.

I'm surprised nobody else has commented that we saw this about 3
months ago.  Tom Van Vleck wrote about CTSS:

Our assumption at the time was that the "rc" comes from this program.
The entire message is in the TUHS archives (29 December 2015, Subject:
" CTSS user interface?".  Let me know if you can't find it.

Yes, I agree.

I see that history added in the CSRG sccs revision 6.2 on 91/03/16. I 
don't know why it says that as it was in 3BSD too. The /etc/rc concept 
wasn't new in 4BSD.

The script was rewritten though for 4BSD to be used for "autoboot". Init 
was extended to run /etc/rc to do a fsck if not booting single user 
mode. (And if the fsck failed it could go into single user mode.)

The history should be fixed to be more clear about.

(For fun, read the usr/man/man0/changes from 4.0BSD about autoboot and 
reboot.)

[TUHS] Again about etymology: rc

[Diomidis Spinellis]

According to "The New Hacker's Dictionary" (Eric Raymond, MIT Press, 
1991) "the startup script /etc/rc is commonly believed to have been 
named after older scripts to 'run commands'".  This name was then 
adopted by other scripts.

[Dan Cross]

They stand for, "run-com" as in "run commands": This was the name for a
scripting facility in, I believe, CTSS.

[TUHS] Again about etymology: rc

[Rocky Hotas]

Hello everyone,
I am Rocky and this is my first message. Before starting, I would like to thank you for all the valuable informations and stories you post here.
About the History of Unix, I was wondering with another guy why the rc script has that name. As many of you already know, and according to NetBSD, FreeBSD, OpenBSD (current) manual,

"The rc utility is the command script which controls" the startup of various services, "and is invoked by init(8)" (from DESCRIPTION).
"The rc command appeared in 4.0BSD" (from HISTORY).

Words may slightly change between the three distributions, but the meaning and the informations provided are the same. So, the etymology of rc does not appear in the man pages. Do you know how to recover it? Do (or did) the letters rc have some meaning in this context?
Cheers,

Rocky
