For a decent number of files, you can use:
sub get_files_count {
my ($dir) = @_;
opendir my $dir_h, $dir or return 0;
# Number of files
return scalar grep { -f "$dir/$_" } readdir $dir_h;
# Number of files+dirs
return scalar @{[readdir $dir_h]} - 2;
}
print get_files_count('./');
Or for a larger number of files, you can use:
sub get_files_count {
my ($dir) = @_;
opendir my $dir_h, $dir or return 0;
my $files = 0;
while(defined(my $file = readdir $dir_h)){
if($file eq '.' or $file eq '..'){ next; }
# Uncomment the bellow line to count only files
# next unless -f "$dir/$file";
++$files;
}
closedir $dir_h;
return $files;
}
print get_files_count('./');

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).
