Facing with a data file which contains more than 7 million lines, I need to
delete all lines containing<patternA> but not containing<patternB>.
So far the only way I can think of is kind messy, something like this:
:g/<patternB>/s/<patternA>/<patternC>/
:g/<patternA>/d
:%s/<patternC>/<patternA>/
But I really like to know how this can be done in a better way, like a
single global replacement command or something.
Dr. Chip's LogiPat.vim makes this less painful. A quick test
suggests that you're looking for something like
:g/\%(.*patternA.*\&^\%(\%(patternB\)\@!.\)*$\)/d
