YES !! it worked.

Now this script will be run again after few minutes again.
At this time we need to take count in the fCOUNT in the last scan. This will be taken as the previous count of errors. We will again scan the file and will count the errors again and this new count will be fCOUNT.

Means the fCOUNT in the last count has become iCOUNT. This iCOUNT will be compared with the new fCOUNT.

Code:
#!/bin/sh
if [  ! -f a.log ]; then
   touch a.log
fi
iCOUNT=`grep -c ERROR a.log`

fCOUNT=`grep -c ERROR b.log`

if [ ${fCOUNT} -gt ${iCOUNT} ]; then
   echo "1"
else
   echo "0"
fi

$fCOUNT > c.log
exit

something like this. We have to compare again & again the previous count because new logs are getting added repeatedly and consequently new errors will be there .

scsi_satl

SCSI_SATL(8)							     SG3_UTILS							      SCSI_SATL(8)

NAME

       scsi_satl - check SCSI to ATA Translation (SAT) device support

SYNOPSIS

       scsi_satl [--help] [--log] [--quiet] [--verbose] DEVICE

DESCRIPTION

       This  Bourne shell script calls several SCSI commands on the given DEVICE that is assumed to be an ATA device behind a SCSI to ATA Transla-
       tion (SAT) layer (SATL). The results of each test and a pass/fail count are output.

OPTIONS

       Arguments to long options are mandatory for short options as well.

       -h, --help
	      print out the usage message then exit.

       -L, --log
	      the output to stderr (from each SCSI command executed) is appended to a file called 'scsi_satl.err' in the  current  working  direc-
	      tory.

       -q, --quiet
	      the amount of output is reduced and typically only the pass/fail count is output.

       -v, --verbose
	      increase level or verbosity.

EXIT STATUS

       The  exit  status  of  this script is the number of "bad" errors found.	So an exit status of 0 means all mandatory SCSI commands worked as
       expected.
