But when I use only
cat file | uniq
some duplicates are not removed. (4 Replies)

sort::key::register
Sort::Key::Register(3pm) User Contributed Perl Documentation Sort::Key::Register(3pm)NAME
Sort::Key::Register - tell Sort::Key how to sort new data types.
SYNOPSYS
use Sort::Key::Register Person =>
sub { $_->surname, $_->name },
qw(string string);
use Sort::Key::Register 'Color::Component' => 'integer';
use Sort::Key::Register Color =>
sub { $_->R, $_->G, $_->B },
('Color::Component') x 3;
DESCRIPTION
Sort::Key::Register allows one to register new data types with Sort::Key so that they can be sorted as natively supported ones.
It works as a pragma module and doesn't export any function, all its functionality is provided via "use":
use Sort::Key::Register ...
To avoid collisions between modules registering types with the same name, you should qualify them with the package name.
use Sort::Key::Register 'MyPkg::foo' => sub { $_ }, '-int';
# or using __PACKAGE__:
use Sort::Key::Register __PACKAGE__, sub { $_ }, '-int';
USAGE
use Sort::Key::Register $name => &multikeygen, @keytypes;
registers type $name.
&multikeygen is the multikey extraction function for the type and @keytypes are the types of the extracted keys.
use Sort::Key::Register $name => $keytype;
this 'use' is useful for simple types that are sorted as another type already registered, maybe changing the direction of the sort
(ascending or descending).
