Question

I’m a bit confused from File::Find documentation… What is the equivalent to $ find my_dir -maxdepth 2 -name "*.txt"?

Personally, I prefer File::Find::Rule as this doesn’t need you to create callback routines.

use strict;
use Data::Dumper;
use File::Find::Rule;

my $dir = shift;
my $level = shift // 2;

my @files = File::Find::Rule->file()
                            ->name("*.txt")
                            ->maxdepth($level)
                            ->in($dir);

print Dumper(\@files);

Or alternatively create an iterator:

my $ffr_obj = File::Find::Rule->file()
                              ->name("*.txt")
                              ->maxdepth($level)
                              ->start($dir);

while (my $file = $ffr_obj->match())
{
    print "$file\n"
}
