Answer: How do I read a directory?
contributed by cLive ;-)

Use the readdir function. To read only certain files, you can use it with grep. For example:

my $dir = '/path/to/dir'; # read all entries: opendir DIR, $dir or die "read dir $dir - $!"; my @dir = readdir DIR; closedir DIR; # read only cgi scripts: opendir DIR, $dir or die "read dir $dir - $!"; my @cgi_scripts = grep /\.cgi$/, readdir DIR; closedir DIR; # read all but (UNIX style) hidden entries: opendir DIR, $dir or die "read dir $dir - $!"; my @dir = grep !/^\./, readdir DIR; closedir DIR;
