NAME

File::Find::Rule::Procedural - File::Find::Rule’s procedural interface

CONTENTS

SYNOPSIS



  use File::Find::Rule;

  # find all .pm files, procedurally
  my @files = find(file => name => *.pm, in => \@INC);



DESCRIPTION

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 );
                                                    ^
                                                    |
               Clause processing stopped here ------/



It is also possible to invert a single rule by prefixing it with ! like so:



 # large files that arent videos
 my @files = find( file    =>
                   !name => [ *.avi, *.mov ],
                   size    => >20M,
                   in      => $ENV{HOME} );
