The following will do what you want. Just change the call to printspaced() so it passes whatever delimiter you want as the first argument.
use strict; use warnings; chomp (my @data = <DATA>); $_ = [split / /] for @data; printspaced(' ', \@data); sub printspaced { my ($s, $d, @f, $f) = @_; push @f, '%-'.$_.'s' for widths($d); $f = join($s, @f)."\n"; printf($f, @$_) for @$d; } sub widths { my ($d, @r, $i) = $_[0]; for (@$d) { no warnings; for ($i = 0; $i <= $#$_; $i++) { $r[$i] = length($_->[$i]) if length($_->[$i]) > $r[$i]; } } return @r; } __DATA__ GAL_up800.fasta 6 800 4.8 hm01g.fasta 18 2008 36.144 hm02r.fasta 9 1000 9 train_muscle.fasta 7 50 0.35
