Remove string from file if found in another file 2

[thedaver]

Oh scripting gurus, my sed's weak and I hate to make perl out of the this....

I have large text file "A" and short text file "B".

"B" represents strings I need to remove (whole line matching) if they appear in "A".

THUS: if "A" is

apple
banana
grape
mango
peach
pear

and "B" is

banana
mango

I want to modify "A" to read:

apple
grape
peach
pear

Again, whole line pattern matching... I'm on very little sleep and this is not clicking for me... I know it's easy..
HELP appreciated.

grep -v -x -f fileb filea

ought to do it. Pipe the output wherever you want.

Hmm... seems I was way too slow. But in my defence, grep doesn't require them to be sorted...
