This is working GREAT!!!
#!/usr/local/bin/perl
use strict;
use warnings;
use feature 'say';
my $text =
q{2013020400000000006810083610022013068100200220130688000200494};
my @offs = ( 17, 6, 31, 3, 3 );
my @cums = ( 0 );
push @cums, $_ + $cums[ -1 ] for @offs;
substr $text, $_, 0, q{-} for reverse @cums[ 1 .. $#cums ];
say $text;
Now what is need to do is to modify all the lines of the file, I know that I need to call the file, like this
open(FILE, "file1.txt") or die "Could not open file: $!";
Am I heading on the right direction?

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.
