File::Find traverses a directory tree and calls the wanted function for each directory entry found. Inside the wanted function, you can use lstat or stat or one of the -X functions to decide if you want to process that directory entry. Example:

#!/usr/bin/perl

use strict;
use warnings;
use File::Find;

find(
        {
                wanted => sub {
                        return unless -l $File::Find::name;
                        print "Found a symlink: $File::Find::name\n";
                }
        },
        '.'
);

File::Find comes with a script named find2perl. You invoke it like find, but instead of traversing directories, it writes perl code for performing the directory traversal using File::Find to STDOUT. The generated code is not pretty, may have some unused parts, but it generally works:

/tmp>find2perl . -type l
#! /usr/bin/perl -w
    eval 'exec /usr/bin/perl -S $0 ${1+"$@"}'
        if 0; #$running_under_some_shell

use strict;
use File::Find ();

# Set the variable $File::Find::dont_use_nlink if you're using AFS,
# since AFS cheats.

# for the convenience of &wanted calls, including -eval statements:
use vars qw/*name *dir *prune/;
*name   = *File::Find::name;
*dir    = *File::Find::dir;
*prune  = *File::Find::prune;

sub wanted;



# Traverse desired filesystems
File::Find::find({wanted => \&wanted}, '.');
exit;


sub wanted {
    my ($dev,$ino,$mode,$nlink,$uid,$gid);

    (($dev,$ino,$mode,$nlink,$uid,$gid) = lstat($_)) &&
    -l _
    && print("$name\n");
}
