File::Find::Rule::Procedural − File::Find::Rule’s procedural interface
use
File::Find::Rule;
# find all .pm files, procedurally
my @files = find(file => name => '*.pm', in =>
\@INC);
In addition to
the regular object-oriented interface, File::Find::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::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' );

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} );
