How to save all google results in a text file

You might be wondering that i am going to share a script with you which will allow you to save all Google search results {links} in a text file for you

Well, unfortunately i don't have such a script with me but i found a website which allows you to search Google & Get Google results in a list of clean URLs

This site uses a Perl script to perform certain search in Google, parse the results and save all the founded URLs in a text file. 

This is extremely useful for a lot of things, for example, I made a search string for Google to find sites that have a security vulnerability, then I run an exploit to all this sites and I founded all the vulnerable sites. Just for research...
