How to store values from a column (in a tab-delimited text file) in Perl

Here is an example of the file. Let's say I want to parse the 6th column values and store them in an array.

You can do:

use strict;

my @arr;    
while(<>) {
        my @tmp = split/\t/;
        push @arr,$tmp[5];
}

and call the script as:

$ perl myprg.pl  file

See it

Alternatively you can treat the file as CSV with tab as the field separator and use an suitable CSV parser module.

Split will be the simplest way

my @ary;
foreach my $line (split(/\n/, $full_text)) {
  my @l = split(/\t/, $line);
  push @ary, $l[5]
}
