in reply to Oddly growing array

This script looks at one .TAB file, compares each line's second tab stop text (probably very inefficiently) to all the other line's second tab stop text. I'm looking for duplicates.

haven't had a chance to read the code but wouldn't something like this do what you want?


#!/usr/bin/perl use strict; use warnings; my %dups; while (<DATA>) { my $col = (split /\t/)[1]; # get the second col $dups{$col}++; # put the text into a hash and increment counter. } print +($_ , " : ", $dups{$_},$/) for (keys %dups); # print the counts
