With Path::Tiny and using the `children` method: `use Path::Tiny 0.028; my $dir = path ('/path/to/dir'); # Retrieve all entries except '.' and '..' my @all = $dir->children (); # Alternatively, retrieve a subset - here just the perl scripts my @perl = $dir->children (qr/\.pl$/);` [download]	[reply] [d/l] [select]

You call `opendir`, then `readdir`, and then `closedir`. Originally posted as a Categorized Answer.	[reply]

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;` [download]	[reply] [d/l]

This is very good, but there is one error: `open DIR, $dir \|\| die $!;` [download] should be: `opendir DIR, $dir \|\| die $!;` [download] - Sherlock	[reply] [d/l] [select]

Don't you mean `opendir DIR, $dir or die $!;` [download] or `(opendir DIR, $dir) \|\| die $!;` [download]	[reply] [d/l] [select]
