Wireshark · Ethereal-users: [Ethereal-users] log files

[teck@xxxxxxxxxxx]

Can anyone suggest how i would setup to parse a log file. This is setup to 
capture traffic and print it to a file. I have used grep to get all the 
lines that are using http and send that to another file. Now i need to 
parse this file and eliminate a majority of the lines.
All i need is the first and last http packet per site accessed,...e.g- if i 
have 30 lines of http traffic to  www.google.com , all i want is the first 
line and the last line of this section

please cc: me at teck@xxxxxxxxxxx , i'm not subscribed to the list right now

thanks
