bash rss reader

Hey all,

This is a bash rss/rdf reader

It will run on any system with wget, grep, cat, head, tail and cut (any linux install I've seen) and a browser of choice

install the script by copying to an executable directory ( /usr/bin for example )

if no browser is chosen, or the chosen browser seems broken, it'll use elinks, links or lynx (in that order)
if none are found it falls back to 'wget-ing' and parsing with sed (if found)

the script takes one or two parameters, url and browser.

I hope you like it..

Code:

#!/bin/bash

declare -i count
ver=0.4
choise=endless
browser=none

#  RDF/RSS reader
#
#        Pretty lame actualy..
#        Could have used some functions instead of c-and-p
#        Might make it to smallest rdf/rss reader
#        For updates check http://etv.cx/~the_jinx/rssread
