Given a url how to get last part of file

HI,

I have a URL that points to a file:

Code:
LINK= "http://www.webpage.org/project/team2/file.tar"

However when I try to use wget on this variable I receive the following error.

Code:
wget $LINK

line 4:   http://www.webpage.org/project/team2/file.tar: No such file or directory
wget: missing URL

The only way I can avoid the error is if I use wget against the URL directly
Code:
wget  http://www.webpage.org/project/team2/file.tar

What I want to be able to do is two things:

1. Take a URL and use wget against it
2. Take the same URL and get the filename from it which in this case would mean printing "file.tar"

The reason that I mention the error is because I want to be able to assign the URL to a variable so I can use it in both cases because I do not want to have to input it twice.

Thanks!

URI::URL(3)						User Contributed Perl Documentation					       URI::URL(3)

NAME
URI::URL - Uniform Resource Locators SYNOPSIS
$u1 = URI::URL->new($str, $base); $u2 = $u1->abs; DESCRIPTION
This module is provided for backwards compatibility with modules that depend on the interface provided by the "URI::URL" class that used to be distributed with the libwww-perl library. The following differences exist compared to the "URI" class interface: o The URI::URL module exports the url() function as an alternate constructor interface. o The constructor takes an optional $base argument. The "URI::URL" class is a subclass of "URI::WithBase". o The URI::URL->newlocal class method is the same as URI::file->new_abs. o URI::URL::strict(1) o $url->print_on method o $url->crack method o $url->full_path: same as ($uri->abs_path || "/") o $url->netloc: same as $uri->authority o $url->epath, $url->equery: same as $uri->path, $uri->query o $url->path and $url->query pass unescaped strings. o $url->path_components: same as $uri->path_segments (if you don't consider path segment parameters) o $url->params and $url->eparams methods o $url->base method. See URI::WithBase. o $url->abs and $url->rel have an optional $base argument. See URI::WithBase. o $url->frag: same as $uri->fragment o $url->keywords: same as $uri->query_keywords o $url->localpath and friends map to $uri->file. o $url->address and $url->encoded822addr: same as $uri->to for mailto URI o $url->groupart method for news URI o $url->article: same as $uri->message SEE ALSO
