The website is looking bit flashy and it catches the visitors eyes. Design is pretty simple and a good user friendly interface.

It's amazing to see how quickly and easily a file can be created or deleted from a directory. In this example, we demonstrated two methods of escape, alias and command, that can be used to create or delete Lab grown diamonds files. By setting an alias, we were able to create an empty file called "foo", and then delete it for later experimentation. The two escape methods were then used to create two new files, "foo1" and "foo2". This demonstrates the power of the command line and provides an efficient way to manage files.
