File::Find::Object::Rule::Procedural - File::Find::Object::Rule's procedural interface
use File::Find::Object::Rule;
# find all .pm files, procedurally
my @files = find(file => name => '*.pm', in => \@INC);
In addition to the regular object-oriented interface, File::Find::Object::Rule provides two subroutines for you to use.
find( @clauses )rule( @clauses )find and rule can be used to invoke any methods available to the OO version. rule is a synonym for find
Passing more than one value to a clause is done with an anonymous array:
my $finder = find( name => [ '*.mp3', '*.ogg' ] );
find and rule both return a File::Find::Object::Rule instance, unless one of the arguments is in, in which case it returns a list of things that match the rule.
my @files = find( name => [ '*.mp3', '*.ogg' ], in => $ENV{HOME} );
Please note that in will be the last clause evaluated, and so this code will search for mp3s regardless of size.
my @files = find( name => '*.mp3', in => $ENV{HOME}, size => '<2k' );

Clause processing stopped here ------/
It is also possible to invert a single rule by prefixing it with ! like so:
# large files that aren't videos
my @files = find( file =>
'!name' => [ '*.avi', '*.mov' ],
size => '>20M',
in => $ENV{HOME} );
