You would use the script like so:

script_name http://www.randomwebsite.com/thisisanm3ufile.m3u

Basically, s/ tells it we're going into replace mode. /g says to do that 
for all of them instead of just the first one it encounters.

I'll attempt at fixing this.

Use like so:

scriptname http://www.website.com/radio.m3u

I have created a new version of my script, it is pasted below:

#!/bin/sh
wget $1 -O /tmp/urlfile && sed -e 's/http:\/\//WORKShttp:\/\//g' -e 
's/rstp:\/\//WORKSrstp:\/\//g' -e 's/pnm:\/\//^WORKSpnm:\/\//g' 
/tmp/urlfile |grep WORKS |sed -e 's/^/BLAH/g' -e 's/BLAH.*WORKS/WORKS/g' 
|sed -e 's/WORKS//g'

Note that my mail client might at some newlines.

This updated version removes any garbage before the URL. Any other 
requests for things you would like this to do?

Also, in order to add a new protocol, in the second section (right after 
the '&& sed -e) copy and paste the -e and a part in quotes and change 
the protocol to the one you please to make it support recognizing more 
protocols.

Thanks,
