- .sh NAME
- su \*- become privileged user
- .sh SYNOPSIS
- .bd su
- .sh DESCRIPTION
- .it Su
- allows one to become the super-user, who has
- all sorts of marvelous (and correspondingly dangerous) powers.
- In order for \fIsu\fR to do its magic, the user must
- supply a password.
- If the password is correct, \fIsu\fR
- will execute the Shell with the UID set to
- that of the super-user.
- To restore normal UID privileges,
- type an end-of-file to the super-user Shell.
- .s3
- The password demanded is that of the entry ``root''
- in the system's password file.
- .s3
- To remind the super-user of his responsibilities,
- the Shell substitutes `#' for its usual prompt `%'.
- .sh "SEE ALSO"
- sh (I)
