in reply to Tidying Up Tabbed Printing

The quickest to implement would be using printf.
#!/usr/bin/perl use strict; use warnings; foreach (<DATA>) { chomp; my @strings = split; printf("%-1s %-13s\t%8s\n", @strings); } __DATA__ D. persimilis ggacaata D. grimshawi tcg----- D. simulans gg---agc D. willistoni aaataaat D. virilis tcg----- D. sechellia --------

But you also have the option of using formats. Using a format would be an advantage if you need a repeated header and/or footer. If you don't then I would stick with printf.

UPDATE: clarified printf vs. format advantages
