rm and ln enhancements -- or a new command -- dog.

To whom it may concern,

I'd like suggest an enhancement to the current commands of fileutils, or the 
addition of a new command (cat needs dog) that accomplishes the following:

I have precisely 1782 (ls -l | grep '^l' | wc -l , I moved the linked 
directory) dead link files in a directory with precisely 1072 (ls -l | grep 
'^-' | wc -l) original files, and I need to kill the dead links.

I've written a script that gets me close to this objective:

#! /bin/bash

# lsln -- list file name only of all files that are links.
# This script lists only files that are links, in either a specified
# directory, or your current directory.

if [ -d "$1" ]; then
        ls -l $1 | grep '^l' | cut -c 57-200 | 
        awk -F " -> " '{ print $1 }'
        ls -l | grep '^l' | cut -c 57-200 | 
        awk -F " -> " '{ print $1 }'

# cool...

but when I either pipe this to rm (lsln | rm -f), or rm with command 
substitution (rm -f $(lsln)), or even try to feed it a list of a saved output 
(rm -f $(cat killthese)  or rm -f "$(cat killthese)), it breaks on file name 
abuses such as spaces and appostrophies.  I've even tried  ls -l | grep '^l' 
| cut -c 57-200 | awk -F " -> " | xargs rm   all to no solution.

So, it would be nice to have a command that wacks dead links.  I suggest the 
dog label cause I teach, and I like the fact that we have less and more.  Why 
not cat and dog?  For that matter, this is now OUR OS, let's start making 
commands named after animals.  It's the whole O'Reily, GNU, open source, 
penguin thing.  Hey, I want to call my up coming Linux configured PCs Orange, 
since I'm in Tampa and not the land of the Apple.

Anyway, I hope you can help me with this.  I'm still pretty narrow and 
shallow in my knowledge of OUR OS, and am working on it.

Thanks in advance.
