I totally followed all of that *until* "g/re/d". What is that?
If I gave you the clue that the program "grep" was named for the ed
command "g/re/p" would that help?
Where "re" stands for "regular expression".

Actually, it would. It would "help", that is. I still would not have
gotten the /d angle, or the g/ angle for that matter. I saw the
similarity to "grep", but the slashes and the "d" at the end threw me.
Unfortunately, I have nearly 0 exposure to ed.
