compare & print lines with 2 requirements

Shell Programming and Scripting
1

1.compare 90 logs >20 print off with correct figure
2.compare latest log i.e ciscoresets_20120314 against all records not just the 90 (as above) and any lines not matching print as:

NEW:SYDGRE04,10,9 1

(note this number could be 2 or whatever not necessary 1 it could be 2,3 or even 10 as ciscoresets_20120314 file could have seen this line multiple times where as no other file has, if you understand logic)

**must also take into account the count of the latest file i.e ciscoresets_20120314
