usually ill do cat /etc/somthing | grep -A999999 #
The problem is that grep is a line filter: it filters lines with a certain attribute from others. If you want to work context-oriented like in your case, where a line is printed or not depending on where in the file (before or after something) it is, you need another tool: sed for instance.
My file creates an output log after which includes a few sql queries.
I segregate them into warnings and errors and then get a total count.
The errors' and warnings' lines always start with SQL{4} followed by the details of the error.

lsdiff
LSDIFF(1)LSDIFF(1)NAME
lsdiff - show which files are modified by a patch
SYNOPSIS
lsdiff [-n] [-p n] [--strip=n] [--addprefix=PREFIX] [-s]
[-i PATTERN] [-x PATTERN] [-v] [file...]
lsdiff {--help | --version | --filter ... | --grep ...}
DESCRIPTION
List the files modified by a patch.
You can use both unified and context format diffs with this program.
OPTIONS -n Display the line number that each patch begins at. If verbose output is requested, each hunk of each patch is listed as well.
For each file that is modified, a line is generated containing the line number of the beginning of the patch, followed by a Tab
character, followed by the name of the file that is modified. If -v is given, following each of these lines will be one line for
each hunk, consisting of a Tab character, the line number that the hunk begins at, another Tab character, the string ``Hunk #'', and
the hunk number (starting at 1).
-p n When matching, ignore the first n components of the pathname.
--strip=n
Remove the first n components of the pathname before displaying it.
--addprefix=PREFIX
Prefix the pathname with PREFIX before displaying it.
-s Show file additions, modifications and removals. A file addition is indicated by a ``+'', a removal by a ``-'', and a modification
by a ``!''.
-i PATTERN
Include only files matching PATTERN.
-x PATTERN
Exclude files matching PATTERN.
-v Verbose output.
--help Display a short usage message.
--version
Display the version number of lsdiff.
--filter
Behave like filterdiff(1) instead.
--grep Behave like grepdiff(1) instead.
SEE ALSO filterdiff(1), grepdiff(1)EXAMPLES
To sort the order of touched files in a patch, you can use:
lsdiff patch | sort -u |
xargs -rn1 filterdiff patch -i
To show only added files in a patch:
lsdiff -s patch | grep '^+' |
cut -c2- | xargs -rn1 filterdiff patch -i
To show the headers of all file hunks:
lsdiff -n patch | (while read n file
do sed -ne "$n,$(($n+1))p" patch
done)
