We are trying to write a script "sendemail.sh" to count the number of occurrence of a particular string in a log file "SendEmail.log" within the given interval. We have a log file. In that we are searching for a pattern "ReqInputMsgLog" and need to count the number of times it occurred in the given period for eg: from "2014-08-19 11:30" to "2014-08-19 11:34". And our script look like this:

#!/bin/sh
enterdate=$1
echo $enterdate
enddate=$2
enterdate1=`date +%s -d $enterdate +"%Y-%m-%d %H:%M"`

echo $enterdate1
enddate1=`date +%s -d $enddate +"%Y-%m-%d %H:%M"`
echo $enddate
count=0
cat SendEmail.log | grep "ReqInputMsgLog" | awk -F "[" '{print $3}' | awk -F "," '{print $1}' > /con/scripts_server/file.txt
for line in `cat /con/scripts_server/file.txt`
do
logdate=`echo $line | awk -F : '{print $1":"$2}'`
if [[ $logdate < $enddate1 ]];
        then
        count=`expr $count + 1`
        fi
done
echo $count

But when we are trying to execute the script by the below command its not showing the proper count.

./sendemail.sh "2014-08-19 11:30" "2014-08-19 11:34"

Log file is very big one. Small chunk has been posted here.

after awk command we will get a file "/con/scripts_server/file.txt" which looks similar like below:
