Thanks a lot agama. but still i have a doubt will this check for the latest update in the log file because there may be updates in logfile for previous days also.
You are correct; my original post indicated that it would snarf from the first occurrence of the timestamp until the end. I didn't catch the part in your original post that indicated you only wanted the last day -- sorry about that.
Along the same lines, but it does not include anything before the last timestamp after 21:59:59. It does assume that every line in the file has a timestamp.
Code:
awk '
BEGIN { i = 0; }
$2+0 < 22 { roll = 1; } # rolled to next day -- signal reset needed
snarf || $2+0 >= 22 {
if( $2+0 >= 22 && roll ) # reset on first timestamp after roll
{
roll = 0;
delete capture;
i = 0;
}
snarf = 1;
capture[i++] = $0;
}
END { # after all of the file has been read, print the lines from the last timestamp of 22:00 or later
for( j = 0; j < i; j++ )
print capture[j];
}' input-file

Reason: clarification
Every time we build an executable the date and time are put into the file, I need to run checksum on just the working lines.(IE, no header files)
Is this even possible, if so how would I go about it?
I am using a HP-UX server any help you can give me will be greatly appreciated.

mrtg-logfile
MRTG-LOGFILE(1) mrtg MRTG-LOGFILE(1)NAME
mrtg-logfile - description of the mrtg-2 logfile format
SYNOPSIS
This document provides a description of the contents of the mrtg-2 logfile.
OVERVIEW
The logfile consists of two main sections.
The first Line
It stores the traffic counters from the most recent run of mrtg.
The rest of the File
Stores past traffic rate averates and maxima at increassing intervals.
The first number on each line is a unix time stamp. It represents the number of seconds since 1970.
DETAILS
The first Line
The first line has 3 numbers which are:
A (1st column)
A timestamp of when MRTG last ran for this interface. The timestamp is the number of non-skip seconds passed since the standard UNIX
"epoch" of midnight on 1st of January 1970 GMT.
B (2nd column)
The "incoming bytes counter" value.
C (3rd column)
The "outgoing bytes counter" value.
The rest of the File
The second and remaining lines of the file contains 5 numbers which are:
A (1st column)
The Unix timestamp for the point in time the data on this line is relevant. Note that the interval between timestamps increases as you
progress through the file. At first it is 5 minutes and at the end it is one day between two lines.
This timestamp may be converted in OpenOffice Calc or MS Excel by using the following formula
=(x+y)/86400+DATE(1970;1;1)
(instead of ";" it may be that you have to use "," this depends on the context and your locale settings)
you can also ask perl to help by typing
perl -e 'print scalar localtime(x),"
"'
x is the unix timestamp and y is the offset in seconds from UTC. (Perl knows y).
B (2nd column)
The average incoming transfer rate in bytes per second. This is valid for the time between the A value of the current line and the A
value of the previous line.
C (3rd column)
The average outgoing transfer rate in bytes per second since the previous measurement.
D (4th column)
The maximum incoming transfer rate in bytes per second for the current interval. This is calculated from all the updates which have
occured in the current interval. If the current interval is 1 hour, and updates have occured every 5 minutes, it will be the biggest 5
minute transfer rate seen during the hour.
E (5th column)
The maximum outgoing transfer rate in bytes per second for the current interval.
