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;
