To help you out, you'd first have to tell me what do you want grep to return? That is the definition of grep: it returns lines of the file containing the regular expression you specify:

GREP(1)                                                                GREP(1)



NAME
       grep, egrep, fgrep - print lines matching a pattern

SYNOPSIS
       grep [options] PATTERN [FILE...]
       grep [options] [-e PATTERN | -f FILE] [FILE...]

DESCRIPTION
       Grep  searches the named input FILEs (or standard input if no files are
       named, or the file name - is given) for lines containing a match to the
       given PATTERN.  By default, grep prints the matching lines.

       In addition, two variant programs egrep and fgrep are available.  Egrep
       is the same as grep -E.  Fgrep is the same as grep -F.

OPTIONS
       -A NUM, --after-context=NUM
              Print NUM  lines  of  trailing  context  after  matching  lines.
              Places  a  line  containing  --  between  contiguous  groups  of

Pay attention to the phrase "grep prints matching lines". Reading the fine manual is sometimes a good idea. Now, that this is out of the way, please explain what you need and thy will shalt be done. There are other utilities, like the pathologically eclectic rubbish lister, which can help you with decomposition of the affected lines.
