I want to make the 2nd,3rd and 4th fields to start with upper case. Second entry has a middle initial which has to made an uppercase too. Entries from the second row should be modified till the end of the file for all the entries. What would be the easiest way to do this. expected result is.

uid,givenname,sn,cn,mail,telephonenumber
