Emacs equivalent of vi's ":v"

Emacs equivalent of vi's ":v"

Hi,
I asked about :g a couple of days ago and I can easily do it in emacs now.
I now would like to do :g stuff. In Vi, :v is the opposite of :g; as in
action is performed on lines that do not match the regex.
Regards,
Kashyap

Look for "all.el" -- show all lines matching regexp in new buffer, any
edits made in the new buffer gets changed at the source.  nifty!

thanks Le, sounds nifty indeed. How do I look for all.el? I use aquamacs and
the only way that I know of is the good old 'find'. I am sure, there should
be a way to do it more efficiently sitting inside emacs.

Vim's :g and :v are not just for deleting or keeping lines. They perform
any action for matching lines.

Great! I start actively use 'flush-lines'. But for
'keep-lines' use M-x occur (M-s o), copy *Occur* content to new
buffer and then delete prefix rectangle.
