Remove duplicate rows of a file based on a value of a column

Hi,

I am processing a file and would like to delete duplicate records as indicated by one of its column. e.g.

COL1 COL2 COL3
A 1234 1234
B 3k32 2322
C Xk32 TTT
A NEW XX22
B 3k32 2322


I want the file not to contain duplicate COL1. i.e. the file should only contain the ff:

COL1 COL2 COL3
A 1234 1234
B 3k32 2322
C Xk32 TTT


The records with duplicate COL1 were deleted.

Anybody who has suggestions on how to do this?

Thank you.
