"Advanced Editing on UNIX" by Brian W. Kernighan, Bell
Laboratories, Murray Hill, New Jersey 07974, August 4, 1978,
says:
"The program <b>grep</b> was invented to get around these
limitations [as described previously for <b>ed</b>]. The
search patterns that we have described in the paper are
often called 'regular expressions', and 'grep', stands for
g/re/p
That describes exactly what <b>grep</b> does -- it prints
every line in a set of files that contain a particular
pattern."
This is from the "UNIX Time Sharing System: UNIX
Programmer's Manual" as published by Holt, Rinehart and
Winston in 1983. I've got the original Bell Labs memo in my
archives somewhere, but I'm pretty sure this is what I
remember reading when I first met 6th Edition UNIX in the
late 70's.
