Hi,
Thanks for your replies, actually I tried both the methods but it doesnt seem to pick up the log entries between the start and end times, The above code

STOP_LINE=`grep -n "End - 07/Aug/2008:19:36:43" request.log | cut -f1 -d:`
LAST_PART=`expr $TOT_LENGTH - $START_LINE`
DIFF_START_END=`expr $STOP_LINE - $START_LINE`
tail -$LAST_PART request.log | head -$DIFF_START_END
###
Gives a syntax error

I tried using the following methods also but without any result

1. awk /'06\/Aug\/2008:18:26:43/,/06\/Aug\/2008:18:36:43/' request.log

2. sed -n -e '/06\/Aug\/2008:18:26:43/,/06\/Aug\/2008:18:36:43/' -e '/06\/Aug\/2008:18:36:43/q' request.log

3. awk '/06\/Aug\/2008:18:26:43/&&f{exit}f;/06\/Aug\/2008:18:36:43/{f++}' request.log

A sample log entry is as follows

198.232.219.21 - ukla_portal_23@ukla.com [07/Aug/2008:14:51:23 -0400] "GET HTTPS://modulemgr.stage.ukla.com/mys...e_services.gif HTTP/1.1" 200 148
198.232.219.21 - ukla_portal_23@ukla.com [07/Aug/2008:14:55:23 -0400] "GET HTTPS://modulemgr.stage.ukla.com/mys...vice_green.gif HTTP/1.1" 200 3168
198.232.219.21 - ukla_portal_23@ukla.com [07/Aug/2008:15:05:23 -0400] "GET HTTPS://modulemgr.stage.ukla.com/mys.../gray_line.gif HTTP/1.1" 200 371

The above is just a sample and there are close to 10000 lines in a log file in an hour.

Please help me in finding the entries between two points (Start - End )

Your help is greatly appreciated !

Thanks
