Expansion of the acronym "grep"

[Gregory Kemnitz]

I read in a UNIX book (I forgot which one) at some time that "grep"
stands for the commands from the ed(1) editor that can be used to approximate
it:

g/re/p

which is read as get /regular_expression/ print.

egrep is extended grep with more general regular expressions than those in
ed(1)
fgrep is fast grep with literal strings only.
