Remove duplicates based on a column in fixed width file
Hi,

How to output the duplicate record to another file. We say the record is duplicate based on a column whose position is from 2 and its length is 11 characters.
The file is a fixed width file.

ex of Record:

DTYU12333567opert tjhi kkklTRG9012

The data in bold is the key on which the duplicates are identified.

Thanks.

You want duplicates in a second file, singletons in another.
This creates two files: single.txt duplicate.txt
Code:
awk '{if (arr[substr($0,2,11)]++) {print $0>"duplicate.txt"} else{print $0>"single.txt" }} ' inputfile
