.B Su
|
|
can be used to temporarily run a shell under the identity of the superuser
|
|
or another user. Unless the caller is a member of the operator group, one
|
|
is prompted for the password of the user-to-be. Calls that need a password
|
|
are logged, whether they succeed or not. The default user is
|
|
.BR root .
|
|
Further arguments are handed to the shell. By default the shell started is
|
|
the shell of the invoker, and the environment is passed on as is.
|
|

|
The activities of
|
|
.B su
|
|
are logged through
|
|
.BR syslog (3)
|
|
under Minix-vmd.
