1) Copy ("passwd" "shadow" "/security/access.conf") to a new file location
2) Do , md5sum "/etc/passwd" "CopiedFile-Passwd"  >tmp/HPOM_Checksum.log
3) Do , md5sum -c /tmp/HPOM_Checksum.log
     if ("passwd" "shadow" "/security/access.conf") gets modified , the md5sum o/p string will be different
This can be checked from 
4) md5sum -c /tmp/HPOM_Checksum.log
sample o/p 
[root@oilvs011 tmp]# md5sum -c /tmp/HPOM_Checksum.log
/etc/passwd: FAILED
/var/opt/OV/log/hpom_passwd.md5: OK

5) If this gets modified , i again want to run the same loop.

#!/bin/sh
CHECKSUM_PATH=/etc
AGENT_LOG=/var/opt/OV/log
declare -a arr=("passwd" "shadow" "/security/access.conf")
##now loop through the above array
for i in "${arr[@]}"
do
    LIST_FILE=`ls -lrt "$AGENT_LOG" |grep "hpom_$i.md5" |wc -l`
echo $LIST_FILE
if [ $LIST_FILE -eq 0 ]; then
    COPY=`cp "$CHECKSUM_PATH/$i" "$AGENT_LOG/hpom_$i.md5"`
fi
done
declare -a arr=("passwd" "shadow" "/security/access.conf")
##now loop through the above array
for j in "${arr[@]}"
   do
     CHECKSUM=`md5sum "$CHECKSUM_PATH/$j" "$AGENT_LOG/hpom_$j.md5" >/tmp/HPOM_Checksum.log`
     CHECKSUM_STATUS=`md5sum -c /tmp/HPOM_Checksum.log |grep FAILED |wc -l`
     echo $CHECKSUM_STATUS
       if [ $CHECKSUM_STATUS -eq 1 ]; then
          COPY=`cp "$CHECKSUM_PATH/$j" "$AGENT_LOG/hpom_$j.md5"`
          echo `date +%b/%d/%Y-%H:%M:%S` Checksum Failed for $i >> /tmp/HPOM_Log_Checksum.log
       fi
   done
