<p>
16+
There are people who use Perl for tasks in <b>system administration</b> or in
17+
<b>configuration management</b>.
18+
<br />
19+
Others build <b>web sites</b> or <b>web application</b> using Perl.
20+
</p>
21+
22+
<p>
23+
Yet others only need it for <b>small scripts</b>. Or so they were told.
24+
</p>
25+
26+
<p>
27+
Some people use Perl for <b>Bioinformatics</b> or for some other form of
28+
<b>scientific calculations</b>.
29+
</p>
30+
31+
<p>
32+
There are a lot of people using Perl for <b>test automation</b>.
33+
That's one of my favorite fields.
34+
</p>
35+
36+
<p>
37+
The Perl Maven web site was created for all of these people. It's aim is to
38+
<b>help you get your job done</b>.
39+
</p>
40+
41+
<p>
42+
<b>Learning Perl</b> is a funny thing. On one hand, after a few hours of reading
43+
you can already create small scripts and be productive. On the other hand, even after years
44+
if using Perl daily you will find new things. Either in the language or on CPAN.
45+
The learning curve is flat but long.
46+
</p>
47+
48+
<p>
49+
According to <a href="http://en.wikipedia.org/wiki/Maven">Wikpedia</a>:
50+
<p>
51+
52+
<p>
53+
<b>A maven is a trusted expert in a particular field, who seeks to pass knowledge on to others.</b>
54+
</p>
55+
56+
<p>
57+
My hope is that if you follow the articles of this site, read the books an watch the video lectures
58+
you will constantly improve your Perl expertise. Soon you can <b>become a Perl Maven</b>.
59+
</p>
60+
61+
<p>
62+
The site will contain articles available to all free of charge.
63+
We will have several <a href="/perl-books">Perl books</a> and <a href="/perl-videos">video courses</a> for sale.
64+
</p>
65+
66+
<h2>Versions of Perl</h2>
67+
68+
<p>
69+
I am sure you are wondering what version if Perl I am going to cover. For now I'll stick to Perl 5 and
70+
publish the Perl 6 related articles on my personal site. After all Perl 5 is what is used in production.
71+
Within Perl 5 I'll try to be pragmatic. While I would really like to see more people move forward and use the newest releases
72+
of perl I have to be realistic. In many companies that's impossible. I'll try to make sure the solutions I show can work on
73+
the perl 5.8 family but I'll point out when it is necessary to use a newer version of Perl.
74+
</p>
75+
<p>
76+
You will see how using a newer version of Perl can improve your code and you will also see how to reach the point that you can use that Perl.
77+

Reading this <b>Advanced Perl book</b> will teach you how to create modules and classes
20+
and in general how to write and maintain advanced Perl code.
21+
22+
It will teach you how to write Object Oriented code in the modern way, using <b>Moose</b>,
23+
or by using only core Perl: manually blessing references.
24+
25+
While many people use Perl as procedural language with Object Oriented features,
26+
Perl also has capabilities to use it as a functional programming language.
27+
This book will teach you a number of such techniques.
28+
29+
It is based on many years of experience teaching Perl,
30+
blended with the modern features of Perl and CPAN.

15+
In this episode of the <a href="/perl-tutorial">Perl tutorial</a> we are going to see <b>how to append to files using Perl</b>.
16+
17+
In the previous episode we learned <a href="/writing-to-files-with-perl">how to write to files</a>.
18+
That's good when we are creating a file from scratch, but there are cases when you would rather keep the original file,
19+
and only add lines to the end.
20+
21+
The most prominent case is when you are writing a log file.
22+
23+
=abstract end
24+
25+
Calling
26+
27+
<code lang="perl">
28+
open(my $fh, '>', 'report.txt') or die ...
29+
</code>
30+
31+
Opening a file for writing using the <hl>></hl> sign will delete the content of the file if it had any.
32+
33+
If we would like to <b>append</b> to the end of the file we use <b>two greater-than</b> signs <hl>>></hl> as in this example:
34+
35+
<code lang="perl">
36+
open(my $fh, '>>', 'report.txt') or die ...
37+
</code>
38+
39+
Calling this function will open the file for appending. that means the file will remain intact
40+
and anything your <hl>print()</hl> or <hl>say()</hl> to it will be added to the end.
41+
42+
The full example is this:
43+
44+
<code lang="perl">
45+
use strict;
46+
use warnings;
47+
use 5.010;
48+
49+
my $filename = 'report.txt';
50+
open(my $fh, '>>', $filename) or die "Could not open file '$filename' $!";
51+
say $fh "My first report generated by perl";
52+
close $fh;
53+
say 'done';
54+
</code>
55+
56+
If you run this script several times, you will see that the file is growing.
57+
Every run of the script will add another row to the file.
58+
