The  -U  playername  option  supplies the answer to the
          question "Who  are  you?".    It  overrides  any  name  from
          NETHACKOPTIONS,  USER,  LOGNAME,  or  getlogin(), which will
          otherwise be tried in order.  If none of  these  provides  a
          useful name, the player will be asked for one.  A playername
          suffix or a separate option consisting of one of -A -B -C -E
          -H  -K  -P  -R  -S  -T  -V  -W  can be used to determine the
          character role.  

               The -S option alone will print out  the  list  of  your
          scores.   It  may be followed by arguments -A -B -C -E -H -K
          -P -R -S -T -V -W to  print  the  scores  of  Archeologists,
          Barbarians,    Cave(wo)men,    Elves,    Healers,   Knights,
          Priest(esse)s,  Rogues,  Samurai,  Tourists,  Valkyries,  or
          Wizards.   It  may  also  be  followed by one or more player
          names to print the scores of the players  mentioned,  or  by
          'all' to print out all scores.
