Hi,

In the above column 2,3,4 of the file input.txt are key columns and I have to remove duplicates on these columns. Once that is done I need to make the script generic so that I will accept comma seperated list of columns and file name and script should remove duplicates over the keys.
The first code fragment is working fine when the key column numbers are har coded inside awk but when I try to pass the column list as a variable trying to imitate the first code fragment it isn't working.
