Assuming by unique you mean 100% unique, and things like case or white space are included in the uniqueness:

Code:
use strict;
use warnings;
my %unique;
open my $FH, '/path/to/your/file' or die "$!";
while(<$FH>) {
    chomp;#<-- remove this line if the record seperator should be incuded
    $unique{$_};
}
close $FH;
foreach my $line (keys %unique) {
     print "$line = $unique{$line}\n";
}

Next time some effort on your part to first try and solve your programming requirements would be nice to see.

wsreg_set_unique_name

wsreg_set_unique_name(3WSREG)			    Product Install Registry Library Functions			     wsreg_set_unique_name(3WSREG)

NAME

       wsreg_set_unique_name, wsreg_get_unique_name - set or get the unique name of a component

SYNOPSIS

       cc [flag ...]  file ...-lwsreg [library ...]
       #include <wsreg.h>

       int wsreg_set_unique_name(Wsreg_component *comp, const char *unique_name);

       char *wsreg_get_unique_name(const Wsreg_component *comp);

DESCRIPTION

       The  wsreg_set_unique_name()  function  sets  the unique name specified by unique_name in the component specified by comp.  Every component
       must have a unique name before being registered.  If a unique name has already been set in the specified component, the	resources  associ-
       ated with the previously set unique name are released.

       The  wsreg_get_unique_name()  function  gets  the  unique  name	string from the component specified by comp.  The resulting string must be
       released by the caller.

RETURN VALUES

       The wsreg_set_unique_name() function returns a non-zero value if the unique name was set correctly; otherwise it returns 0.

       The wsreg_get_unique_name() function returns a copy of the unique name from the specified component.
