NUKE(8)                                                   NUKE(8)

       nuke - launch nuclear weapons at known sites.

       /sbin/nuke [-y yield] [-a height] [-hcme] sitename...

       Nuke  utilises  the GPOS records in the Domain Name System
       to target and launch nuclear weapons at other UNIX  sites,
       specified by machine name.

       If  no  GPOS  records are found for the site, nuke employs
       the `missile coordinate' fields in the USENET map database
       and  Internet  connections  to  a  server  interfaced with
       AUTOVON to locate coordinates for the specified site.

       The -y option specifies a yield.  The argument must  be  a
       number  suffixed by K or M, for kiloton or megaton respec­
       tively.  Yield arguments above 255M are  quietly  ignored.
       If  this option is not specified a default of 25K is used.

       The -a option specifies an air-burst height in meters.  If
       this option is not specified a default of 1 (ground burst)
       is used.

       The -h option specifies thermonuclear (hydrogen)  weapons.

       The  -c option specifies cobalt-jacketed warheads for per­
       manent site interdiction.

       The -m  option,  useful  with  multiple-site  nuke  calls,
       invokes  code  which  optimizes delivery using MIRVed war­
       heads to minimize launches.

       The -e option requests disablement of  computer  equipment
       by  way  of  EMP pulse only.  This option should leave the
       lusers intact, however those with pacemakers may not  sur­

       In  accordance with the normal UNIX design philosophy nuke
       does not prevent you from nuking yourself.

       /usr/lib/maps/*          USENET map file database

       If a target site has given only  nearest-city  coordinates
       in its map entry, incorrect targeting and significant col­
       lateral casualties may result.

       If no coordinates can be found for the target  site,  nuke
       should  cancel  the launch.  Behaviour in this instance is
       indeterminate, especially if pmsd(8) is running.

       Heavy use of nuke may cause EMP  effects  which  interfere
       with Internet service.

       Nuke  does  not make enough of an effort to locate coordi­
       nates, and may be subject to corrupted data.

       This command is restricted to super-users only.
