<H2>DESCRIPTION</H2><PRE>
|
|
|
|
<EM>Su</EM> can be used to temporarily login as another user. It prompts for the
|
|
superuser password. If the correct password is entered, <EM>su</EM> creates a
|
|
shell with the desired uid. If no name is specified, <EM>root</EM> is assumed.
|
|
To exit the temporary shell, type CTRL-D. When memory is tight, it is
|
|
better to become superuser by logging out and then logging in again as
|
|
<EM>root</EM>, rather than using <EM>su</EM> since the latter creates an extra shell in
|
|
memory. Any user with a zero group id need not type a password. This
|
|
makes life easier for the system administrator.
