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



NAME
     lock - reserve a terminal

SYNOPSIS
     lock [ -p ] [ -t timeout ]

DESCRIPTION
     _L_o_c_k requests a password from the user, reads it again for
     verification and then will normally not relinquish the ter-
     minal until the password is repeated.  There are two other
     conditions under which it will terminate: it will timeout
     after some interval of time and it may be killed by someone
     with the appropriate permission.  The default time limit is
     15 minutes, which may be changed with the -_t option where
     _t_i_m_e_o_u_t is the time limit in minutes.  The -_p option causes
     _l_o_c_k to use the user's current password instead of request-
     ing another one.
