What is directory operations (opendir/readdir) in Perl?

Directory operations in Perl, particularly using the functions opendir and readdir, allow you to interact with the file system to read the contents of directories. This is useful for tasks such as listing files, checking for existing files, or filtering specific file types.

Example of using opendir and readdir

Below is a simple example demonstrating how to open a directory and read its contents using Perl:

#!/usr/bin/perl use strict; use warnings; my $dir = '/path/to/directory'; # Specify your directory path opendir(my $dh, $dir) or die "Cannot open directory: $!"; while (my $file = readdir($dh)) { print "$file\n"; # Print each file name } closedir($dh);
