I have a file of BibTeX entries. Each one looks something like this:

 @ARTICLE{klitzing:nobel,
    AUTHOR="Klaus von Klitzing",
    TITLE="The Quantized Hall Effect",
    JOURNAL=RMP,
    VOLUME=58,
    PAGES=519,
    YEAR=1986
 }
[download]

I need to run a search on the entries that will result in all the compleate entries matching the paramaters being in their own file. I know how to use files and grep, what I was wondering was what the best way of finding out what entry you're in is.

The problem with grep is that it just returns the matching line, which doesn't do me much good at all.

I could store each entry in an array and search it, but that seems very wasteful, so I'm trying to avoid that aproach.

Thanks in advance.
Good day, Meshach
