How do find and delete lines?

[whatisthis987]

I have fileA consists of keywords:
aaa
bbb
ccc

And fileB consists of fulldata

I would like to the lines in fileB that contains any of the fileA keywords. For example,

line1 sdfffffffff
line2 sdfaaaaaaaa
line3 sdfghhrwwww

The output should be
line1 sdfffffffff
line3 sdfghhrwwww


Please help. Thanks.

[tt]grep -vf fileA fileB > fileC[/tt]

Thanks Annihilannic. but the keywords that I tried to find has a space in between. Instead of "aaa", I'm actually looking for "aaa bbb" in the same line. How do i do this?

That should still work as long as they appear exactly the same in both files. Show me an example where it doesn't work?
