NAME
       lock - reserve a terminal

SYNOPSIS
       lock [ -number ]

DESCRIPTION
       _L_o_c_k requests a password from the user, reads it again for verification
       and then it will normally not relinquish the terminal until  the  pass‐
       word is repeated. There are three other conditions under it will termi‐
       nate: it accepts the password for root as an  alternative  to  the  one
       given  by the user, it will timeout after some interval of time, and it
       may be killed by somebody with the appropiate permission.  The  default
       time  limit is 15 minutes but it may be changed with the -number option
       where _n_u_m_b_e_r is the time limit in minutes.
