Perhaps the following will help:

use strict; use warnings; my %seen; while (<DATA>) { chomp; print "$_\n" unless $seen{$_}++; } __DATA__ 30380868 N Sep 29 356200 AGEC682569 ATI + S 30380868 N Sep 29 356200 AGEC682569 ATI + S 71130740 N Sep 7 SM9481 AGEC683966 ATI + S 71130740 N Sep 7 SM9481 AGEC683966 ATI + S 32450045 N Jul 14 SN9672 AGEC685203 ATI + S 32450045 N Jul 14 SN9672 AGEC685203 ATI + S 36450223 N Aug 30 SU8329 AGEC685348 ATI + S 34680135 N Sep 30 349450 AGEC685442 ATI + S

Output:

30380868 N Sep 29 356200 AGEC682569 ATI + S 71130740 N Sep 7 SM9481 AGEC683966 ATI + S 32450045 N Jul 14 SN9672 AGEC685203 ATI + S 36450223 N Aug 30 SU8329 AGEC685348 ATI + S 34680135 N Sep 30 349450 AGEC685442 ATI + S

I want to print the one with "**" as 2nd column and ignore the rest of duplicates..

Doesn't this raise the issue of the indistinguishability of identicals?

The script prints only unique records. chomp is used in case the last line of data above doesn't end with a newline.
