Question

I have a text file containing two or more types of lines. I would like to separate it into two different files.
I do that with this list of commands :

:%g/myregexpforlinetype1/ . w >> file1
:%g/myregexpforlinetype1/d
:w file2

But I think it is not optimal.
How could I make this more generic, more robust, more efficient ?

Thanks

You can use the fact that :v matches all lines not matching a search expression combined with the fact that // will repeat the previous search:

:%g/myregexpforlinetype1/ . w >> file1
:%v// . w >> file2
