Thank you @Yoda....
But I used the segment with awk in your other post in my code as below ... That worked fine too.. Thanks a lot

Code:
join -t"," -1 1 -2 1 -a1 file1.csv file2.csv | awk -F, ' BEGIN {
         print "ID,field,old,new"
 } NF > 3 { 
        if ( $3 != $5 )   
              print $1, "cost", $3, $5        
       if ( $2 != $4 )              
            print $1, "version", $2, $4 } ' OFS=, 

echo "the IDs which are not present in first file are ">>file3000.csv 
awk -F, 'NR==FNR{_1[$1]++;next}!_1[$1]' file81.csv file82.csv >> file3000.csv 
cut -d',' -f1 file3000.csv>>file3001.csv 
cat file3001.csv  

echo "the IDs which are not present in second file are ">>file4000.csv 
awk -F, 'NR==FNR{_1[$1]++;next}!_1[$1]' file82.csv 
file81.csv >> file4000.csv cut -d',' -f1 file4000.csv>>file4001.csv 
cat file4001.csv

In addition to list down the differences in fields(cost / version) between 2 files I also needed to create a new file
which contains the missing IDs in a file compared to the other... The o/p which I got is as below...

ID,field,old,new
2000,cost,40,45
3000,version,3,4
3000,cost,50,55
the IDs which are not present in first file are
6000
7000
the IDs which are not present in second file are
4000
8000

And can I attain the same result as mentioned above using perl scripting?..
In that case what changes should I make?... I went through Perl script basics but it seemed to be different altogether from bash/ksh...
