Removed!
Sorry, I misread the question. :-(
OK, (after reading the question properly) here's another way to do it. :-)
#!perl
use 5.12.0;
use warnings;
use List::Util qw{sum};
my @table = ();
while (<DATA>) {
push @table, [ split ];
}
for my $col (0 .. $#{$table[0]}) {
say qq{Column $col = }, sum map { $table[$_][$col] } (0 .. $#table
+);
}
__DATA__
1 2 3 4 5 6
1 2 3 4 5 6
Output:
$ column_sum.pl
Column 0 = 2
Column 1 = 4
Column 2 = 6
Column 3 = 8
Column 4 = 10
Column 5 = 12
Update:
My apologies if anyone noticed this kept changing and wondered what the hell was going on.
My main intent was just to highlight the sum function in List::Util.

Are you posting in the right place? Check out Where do I post X? to know for sure.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
