I have text files I need to extract website links from, but they are in variable positions.

These lines will all be in one text file, and I need to find and pull out only the links.

Examples:

I received the link and it is http://www.google.com/
Bob sent me the best website and I sent it to him:http://www.yahoo.com
Please update to http://www.dropbox.com and I'll get it back to you asap.

dos or linux or python suggestions?
