SU(1) UNIX Programmer's Manual SU(1)

NAME

    su  -  substitute user id temporarily

SYNOPSIS

    su [ userid ]

DESCRIPTION

    _S_u demands the password of the specified _u_s_e_r_i_d, and if it
    is given, changes to that _u_s_e_r_i_d and invokes the Shell _s_h(1)
    without changing the current directory or the user environ-
    ment (see _e_n_v_i_r_o_n(5)).  The new user ID stays in force until
    the Shell exits.

    If no _u_s_e_r_i_d is specified, `root' is assumed.  To remind the
    super-user of his responsibilities, the Shell substitutes
    `#' for its usual prompt.
