| 14 | .B Su
|
|---|
| 15 | can be used to temporarily run a shell under the identity of the superuser
|
|---|
| 16 | or another user. Unless the caller is a member of the operator group, one
|
|---|
| 17 | is prompted for the password of the user-to-be. Calls that need a password
|
|---|
| 18 | are logged, whether they succeed or not. The default user is
|
|---|
| 19 | .BR root .
|
|---|
| 20 | Further arguments are handed to the shell. By default the shell started is
|
|---|
| 21 | the shell of the invoker, and the environment is passed on as is.
