    You want the printf function.

    For example:

    #! /usr/bin/perl -w use strict; use diagnostics; my $n=42; printf "%05d\n", $n;
    See sprintf for details of the first argument to printf.

[Discipulus]: iirc active perl has repositories only for last 2 o 3 major release of perl Mj1234. I strongly suggest portable version of strawberry perl and use cpan client to install modules
[choroba]: Also, who needs GDB when there's hdb?
[Discipulus]: in this ubuntu i'm not able to find resource monitor, graphical mount program.. just office and amazon are exposed!
