hey,
If you use su you will still have the same enviroment, for example the $PATH variable, as the user who su'd.
If you use su - you will have the envioroment of the user you su'd to.
the diff between "su" and "su -" is "su -" you log in as a root with the env setting/profile (i.e you really log in as a root). just type "pwd" and you will be in the root home dir @ /root.
if you "su" only then basically you just "borrow" the root permission without having all the root env setting/profile . just "su" from your home dir and type "pwd", you can see that you still in the user dir i.e /home/user
