Praveen,
Coincidently, my solution is very similar to yours.
The issue that I see in your solution is the fact that you are loading
the entire file into one string.
This can cause problems in the performance for large files.
Here is my solution not loading the entire file into a string:

Code:

typeset -i mPctLimit=50
typeset -i mTimeLimit=3

mInpFile='b'
mTimeRE='[0-9][0-9]:[0-9][0-9]:[0-9][0-9]'
mHHRE='[0-9][0-9]'
mMMSSRE='[0-9][0-9]:[0-9][0-9]'

mPerctLine=`sed -n '/.*%.*/p' ${mInpFile}`
mPerctValue=`echo ${mPerctLine} | sed 's/.*(\([0-9].*\)%).*/\1/'`
echo "mPerct = "$mPerctValue" limit = "${mPctLimit}
if [ ${mPerctValue} -gt ${mPctLimit} ];then
 echo "Above the percentage limit"
fi

mHoursLine=`sed -n "/.*${mTimeRE}.*/p" ${mInpFile}`
mHoursValue=`echo ${mHoursLine} | sed "s/.*\(${mHHRE}\):${mMMSSRE}.*/\1/"`
echo "mHours = "$mHoursValue" limit = "${mTimeLimit}
if [ ${mHoursValue} -gt ${mTimeLimit} ];then
 echo "Above the time limit"
fi

utmpset

utmpset(8)						      System Manager's Manual							utmpset(8)

NAME

       utmpset - logout a line from utmp and wtmp file

SYNOPSIS

       utmpset [ -w ] line

DESCRIPTION

       The utmpset program modifies the user accounting database utmp(5) and optionally wtmp(5) to indicate that the user on the terminal line has
       logged out.

       Ordinary init(8) processes handle utmp file records for local login accounting.	The runit(8) program doesn't include code  to  update  the
       utmp file, the getty(8) processes are handled the same as all other services.

       To enable local login accounting, add utmpset to the getty(8) finish scripts, e.g.:

	$ cat /service/getty-5/finish
	#!/bin/sh
	exec utmpset -w tty5
	$

OPTIONS

       -w     wtmp. Additionally to the utmp file, write an empty record for line to the wtmp file.

EXIT CODES

       utmpset returns 111 on error, 1 on wrong usage, 0 in all other cases.
