SU(1) UNIX Programmer's Manual SU(1)
NAME
su - substitute user id temporarily
SYNOPSIS
su [ userid ]
DESCRIPTION
_▶08◀S_▶08◀u demands the password of the specified _▶08◀u_▶08◀s_▶08◀e_▶08◀r_▶08◀i_▶08◀d, and if it
is given, changes to that _▶08◀u_▶08◀s_▶08◀e_▶08◀r_▶08◀i_▶08◀d and invokes the Shell
_▶08◀s_▶08◀h(1) without changing the current directory. The user
environment is unchanged except for HOME and SHELL, which
are taken from the password file for the user being sub-
stituted (see _▶08◀e_▶08◀n_▶08◀v_▶08◀i_▶08◀r_▶08◀o_▶08◀n(5)). The new user ID stays in force
until the Shell exits.
If no _▶08◀u_▶08◀s_▶08◀e_▶08◀r_▶08◀i_▶08◀d is specified, `root' is assumed. To remind
the super-user of his responsibilities, the Shell substi-
tutes `#' for its usual prompt.

sh(1)
BUGS
Local administrative rules cause restrictions to be placed
on who can _▶08◀s_▶08◀u to `root', even with the root password.
These rules vary from site to site.
