My knowledge of g
in vi is kind of ironic. I first learned about
it when I learned the etymology of grep. It was from the ed
command g/re/p
. Ed wasn’t a visual editor. You essentially kept
the file in your head and then could bring it up line by line - and change
it line by line - in an editor. So the g/re/p
command was really useful
because you could print all lines (p
) that matched a pattern (re
)
over the entire file (g
).
I found that interesting but nearly all my uses of g
in vim
are g/re/d
. In other words instead of printing, I use it to delete
lines.
So I found cks’s more considered exploration of g
really
interesting. Currently busy at FOSDEM so can’t explore too
much. This post is a reminder to me to go explore later!
