in reply to getting picky with File::Find

I think File::Find::Rule is easier to use so here's my attempt, using glob to get just the abc* directories. This ignores everything below baby/dead directories.

use v5.18;
use warnings;
use autodie;

use File::Find::Rule;

my $rule = File::Find::Rule->or(
                File::Find::Rule->name('baby','dead')
                ->directory()
                ->prune()
                ->discard()
                ,
                File::Find::Rule->file->name('list.dat')
             );

my @files = $rule->in( glob('abc*') );

say "****************";
say for @files;

Re^2: getting picky with File::Find::Rule less typing find/rule
by Anonymous Monk on Apr 09, 2014 at 02:37 UTC

    File::Find::Rule exports rule/find by default, so less typing ; I add find/rule to export list for documentation purposes 

    #!/usr/bin/perl --
use strict; use warnings;
use Data::Dump qw/ dd pp /;
use File::Find::Rule qw/ rule find /;

my @dirs   = find( qw/ directory name abc* in . /);
dd( \@dirs );
my $nobaby = rule( name => [ 'baby', 'dead' ], qw/ prune discard/ );
my $list   = rule( file => name => 'list.dat', );
my @files  = find( not => $nobaby , any => $list, in => \@dirs, );
dd( \@files );

@files = rule()->or(
## !IMPORTANT NOTE discard before prune with rule()/find()
    rule( name => [ 'baby','dead' ], qw/ directory discard prune /),
    rule( qw' file name list.dat ')
)->in(
    find( qw/ directory name abc* in . maxdepth 1 /),
);
dd( \@files );
