Shell script help please

Hi Experts,

I need some help on a shell script. Many thanks in advance.

I have a valid name variable ..eg. VALID=PROD,CAT,ORD,CASH
I do have a txt file with content as below.
Eg. File.txt
XXXX_PROD_YYYY
XX_RES_YYYY
XXX_CAT_YYYY

I need to check if the lines in the file are valid as per VALID assignment.
So in this case line1 and line3 are Valid and line2 is invalid.

Please advice.

Thanks
