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.
