_w_a_k_e_u_p_a_t allows you to specify a time at which the system will power on
by itself. Currently only Indy, Indigo, OCTANE , O2 and Challenge M
support this feature. The syntax for specifying the time is identical to
that of the _a_t(1) command.
If the system is rebooted after this command is used, the _w_a_k_e_u_p_a_t time
is cleared and must be reissued. If the system is not powered off before
the given time, the command has no effect (that is, the system will not
power back on as soon as powered off).
Systems may have a limited range for which power up requests are valid.
For Indy and Indigo, the time must be within one week from the current
date. On OCTANE the time must be within one month of the current date.
Note that the requested date is programmed into the poweron circuitry at
the time the system is shutdown or powered off, and will not take effect
if the system shuts down abnormally. If the date at the time of system
shutdown has been changed so as to be later than the requested power on
time, the system will not power back on automatically.
The _t_i_m_e can be specified as 1, 2, or 4 digits. One and two digit
numbers are taken to be hours, four digits to be hours and minutes. The
time can alternately be specified as two numbers separated by a colon,
meaning _h_o_u_r:_m_i_n_u_t_e. A suffix aaaammmm or ppppmmmm can be appended; otherwise a 24-
hour clock time is understood. The suffix zzzzuuuulllluuuu may be used to indicate
GMT. The special names nnnnoooooooonnnn, mmmmiiiiddddnnnniiiigggghhhhtttt, nnnnoooowwww, and nnnneeeexxxxtttt are also
recognized.
An optional _d_a_t_e can be specified as either a month name followed by a
day number (and possibly year number preceded by an optional comma) or a
day of the week (fully spelled or abbreviated to three characters). Two
special ``days'', ttttooooddddaaaayyyy and ttttoooommmmoooorrrrrrrroooowwww are recognized. If no _d_a_t_e is
given, ttttooooddddaaaayyyy is assumed if the given hour is greater than the current
hour and ttttoooommmmoooorrrrrrrroooowwww is assumed if it is less. If the given month is less
than the current month (and no year is given), next year is assumed.
The optional _i_n_c_r_e_m_e_n_t is simply a number suffixed by one of the
following: mmmmiiiinnnnuuuutttteeeessss, hhhhoooouuuurrrrssss, ddddaaaayyyyssss, wwwweeeeeeeekkkkssss, mmmmoooonnnntttthhhhssss, or yyyyeeeeaaaarrrrssss. (The singular
