Need logs between timestamp

Hi,

I need to count the number of lines wc command for next 12 hrs in the log file given the starting time in the log (hello.log) looks like the below.

135.63.34.29 - - [17/Nov/2015:10:23:17 -0500] "POST /ShopCart/MyBest HTTP/1.1" 200 6310
130.15.126.22 - - [17/Nov/2015:10:23:17 -0500] "POST /ShopCart/MyBest HTTP/1.1" 200 4021
130.18.16.2 - - [17/Nov/2015:10:23:19 -0500] "POST /ShopCart/MyBest?wsdl HTTP/1.0" 200 7391
........

Can you please let me know how can i achieve this ? I m o Linux OS.

Is your example the hello.log file, or the log file you are looking through to get a line count?

Given the start line is in a file, try

awk 'FNR==NR {SRCH=$0; next} ($0 == SRCH),EOF {CNT++} END {print CNT}' STARTLINE hello.log
