How to extract duplicate rows
I have searched the internet for duplicate row extracting.
All I have seen is extracting good rows or eliminating duplicate rows. How do I extract duplicate rows from a flat file in unix. I'm using Korn shell on HP Unix. For.eg. FlatFile.txt ======== 123:456:678 123:456:678 123:456:876 345:457:987 345:457:987 345:123:745 The output should be OutPutFile.txt ============ 123:456:678 345:457:987 I appreciate your help in advance. Thanks |
