Question Finding duplicates from positioned substring across lines
I have million's of records each containing exactly 50 characters and have to check the uniqueness of 4 character substring of 50 character (postion known prior) and report if any duplicates are found.

Eg. data...

AAAA00000000000000XXXX0000 0000000000... upto50 chars
AAAA00000000000000XXXY0000 0000000000... upto50 chars
AAAA00000000000000XXXY0000 0000000000... upto50 chars

output:
Duplicates are found for XXXY.

I'm new to unix scripting. Can anyone provide me direction?
