Here is a more verbose solution and assumes that your files are being stored in an array. In the following code, the array is named @files. I have only tested this on files which all have extensions.
my %extensions;
for my $file (sort @files) {
my @split = split(/\./,$file);
my $key = $split[1];
my $num = 1;
if (exists $extensions{$key}) {
$extensions{$key} += $num;
}
else {
$extensions{$key} = $num;
}
}
while (my ($key,$value) = each %extensions) {
print $key." - ".$value."\n";
}
Have a nice day!

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).
