Problem Statement

Walk a given directory and print the names of files matching a given pattern.
(How is "pattern" defined? substring match? DOS pattern? BASH pattern? ZSH pattern? Perl regular expression?)

Note: This task is for non-recursive methods.   These tasks should read a single directory, not an entire directory tree.
Note: Please be careful when running any code presented here.

Let's start with the solution:

use 5.010;
opendir my $dh, '/home/foo/bar';
say for grep { /php$/ } readdir $dh;
closedir $dh;


use 5.010; say while </home/foo/bar/*.php>;


my @filenames = glob('/home/foo/bar/*.php');


my $pattern = '*.c';
my @filenames = glob($pattern);
