Go2Linux posted a guide about recursively delete / erase files with find and rm

First of all, I want to warn you that any command that may delete files should be used with care, you may break or badly damage your Linux and get no warning about what is going to happen. You will only notice when it is too late.
That said, I will show you how to delete files recursively, this is really powerful, and useful.
There are times when you really need to find files under some criteria, and erase them, we will use find and rm to achieve this.
