    Question about logins



    I seem to remember someone telling me about root login.
    Now someone is telling me differnet.
    I thought the - sets the enviroment where as the non dash doesn't.
    Is there a difference between logging in as su and su - ??????

    thanks
    Mace

    check the difference yourself.
    Code:
    su 
echo $PATH
exit
su  -
echo $PATH
    compare the PATH of both. su - adds path of folders accessible by root user only.
    It is amazing what you can accomplish if you do not care who gets the credit.

    Yes, there is. You can read up on su options and explanations here:
