Using su to access another account
command allows you to become another user without logging off.
su cannot be used to simply assume the login of another user;
instead, su can be used under four circumstances:
The superuser (root) can ``su'' to any account.
A user with the su authorization can
``su'' to root (for example, to become
root temporarily after having su'd to a different account).
Users can ``su'' to their own accounts.
A system daemon can ``su'' to an account.
Under ``traditional'' security, any user can ``su'' to any
account with that account's password.
To use su, the appropriate password must be supplied
(unless you are already root). If the password is correct,
su executes a new shell with the real and effective user ID's
that of the specified user. (If the system is running under tight
security, the login user ID is unchanged; otherwise that,
too, is changed to the ID of the specified user.)
