Use the following command to install unrar:

sudo install -c -o $USER unrar /bin

$USER is a default environment variable in the bash shell which contains your username.

sudo install -c -o $USER rar /bin

Do a test-run to see if the installation went properly. In your terminal now enter from any location you want:
