Thank you very much for your fast reply.

Well since my input is already sorted by time, I found out that if I use:
Code:
sort -s -n -k 5

it does the job.

Now I have something like this (which is what I want)

Code:
12:51:16 PM 018* ONL 000021
01:08:35 PM 018* OUT 000021
09:21:44 AM 001* OUT 000034
09:25:05 AM 001* ONL 000034
01:16:48 PM 003* OUT 000048
01:28:15 PM 003* ONL 000048

I want to check the last line of every number in the last column if there is an OUT keyword.
For example here:

Code:
12:51:16 PM 018* ONL 000021
01:08:35 PM 018* OUT 000021

.

Any help on this?

Thank you.

empty-page

EMPTY-PAGE(1)							 ExactImage Manual						     EMPTY-PAGE(1)

NAME

       empty-page - empty page detector of the ExactImage toolkit

SYNOPSIS

       empty-page [option...] {-i | --input} input-file

       empty-page {-h | --help}

DESCRIPTION

       ExactImage is a fast C++ image processing library. Unlike many other library frameworks it allows operation in several color spaces and bit
       depths natively, resulting in low memory and computational requirements.

       empty-page counts dark pixels of a black and white image and decides with a threshold whether the page is most probably empty, and thus can
       be removed from the image processing stream.

OPTIONS

       -i file, --input file
	   Read image from the specified file.

       -m n, --margin n
	   Set width of border margin to skip. For speed reasons, the margin has to be a multiple of 8. The default is 16.

       -p x, --percentage x
	   Set fraction of permissible dark pixels. The default is 0.05 (5%).

       -h, --help
	   Display help text and exit.

EXAMPLES

	   $ empty-page -i test.tif
	   The image has 75461 dark pixels from a total of 1060992 (7.11231%).
	   non-empty

EXIT STATUS

       The exit status is 0 if the image is mostly white, 1 otherwise.
