suppose I have two files list1.cfg and list2.cfg
both files contains differentrecords details
like
List1.cfg

NAME2:25:C:NAME LINE2:
CITY:25:C:City:
STATE:2:C:State:
ZIPCODE:5:N:ZIPCODE:
PHONE1:12:C:HOME PHONE:
PHONE2:12:C:BUSINESS PHONE:

list2.cfg
NAME1:25:C:NAME LINE1:
NAME2:25:C:NAME LINE2:
PHONECNTR:2:N:Number of attemmpts at calling RECALLNUMBER
PHONESTATR:1:C:PHONESTAT of the current RECALLNUMBER
ZONEPHONER:1:C:Time zone of the current RECALLNUMBER
LASTDATER:10ate of last attempt on RECALLNUMBER
LASTTIMER:8:T:Time of last attempt on RECALLNUMBER

FRSTDATER:10ate of first attempt to call RECALLNUMBER
FRSTTIMER:8:T:Time of first attempt to call RECALLNUMBER
FRSTSTATR:2:C:Stat of first attempt to call RECALLNUMBER

Now I want to append contents list2.cfg to list1.cfg(It ispposible using cat list2.cfg >>list1.cfg) but I want to check if content of (record) in list2.cfg is present in list1.cfg then dont append it otherwise append it.

How do I write such shell script in efficient way

Oh, come on. What's with all the homework? This is the easiest thing to do in Linux and a simple Google or reading your text will unveil the answer. Now go and read your books and do your own homework.
