Bug Help required in parsing a csv file

Hi Members, I am stuck with the following problem. Request your kind help

I have an csv file which contains, 1 header record, data records and 1 footer record. Sample is as below

Contents of cm_update_file_101010.csv

cm_update_file_101010, 2

The first line, contains the filename and the number of data records, which in this case is 2. The footer, contains the total number of file records, in this case being 4 including header and footer

I want to write a code to check this. Like, total number of data records(2) +2 should be equal to footer (4) or

Footer (4) - (Number of data records mentioned in the header record (2) = Total number of data records

Can anyone please suggest how can I acheive this from a shell script

Many thanks in advance
