What is the origin of the name "grep"?

     The original UNIX text editor "ed" has a construct g/re/p,
     where "re" stands for a regular expression, to Globally
     search for matches to the Regular Expression and Print the
     lines containing them.  This was so often used that it was
     packaged up into its own command, thus named "grep".  According
     to Dennis Ritchie, this is the true origin of the command.
