How to enable rar\unrar in Ubuntu

As I am in a serious Ubuntu mood at the moment, I thought I would throw up another quick little guide. In order to enable rar\unrar in Linux (this tested in Ubuntu 9.04), open a terminal window and type:

sudo apt-get install rar

Then, after rar is installed, type the following

sudo ln –fs /user/bin/rar /usr/bin/unrar

Now you can extract rar-archives with the default archive manager in Ubuntu! Enjoy!
