This little command will allow you to boot off all the linkdead people from the mud. I find
it annoying to log on and see people sitting around linkdead all the time so here you go. 


Add to the end of act_wiz.c:

void do_unlink( CHAR_DATA *ch, char *argument )
{
    CHAR_DATA *linkdead;
    CHAR_DATA *wch;
    CHAR_DATA *wch_next;
    bool found = FALSE;
    int i = 0;

    if ( argument[0] == '\0' )
    {
        send_to_char( "Unlink <all> or Unlink <player>\n\r", ch );
     
        for ( wch = char_list; wch != NULL; wch = wch_next )
        {
             wch_next = wch->next;
            
             if (IS_NPC( wch ) )
                 continue;        

             if ( wch->desc == NULL )
                 i++;
        }

        send_to_char( "\n\r{C================================================{x\n\r\n\r",ch );
        printf_to_char( ch, "The number of linkdead people on the mud is %d.\n\r", i );
        return;    
    }

    if  ( !str_cmp( argument, "all" ) )
    {
        for ( wch = char_list;  wch != NULL; wch = wch_next )
        {
              wch_next = wch->next;

              if ( IS_NPC( wch ) )
                  continue;

              if ( wch->desc == NULL )
              {
                  found = TRUE;
                  do_function( wch, &do_quit, "" );
              }
        } 

        if ( found )
            send_to_char( "Extracting all linkdead players.\n\r", ch );

        if ( !found )
        send_to_char( "No linkdead players were found!\n\r", ch );
        return;
    }

    if ((linkdead = get_char_world(ch,argument)) == NULL)
    {
        send_to_char("They aren't here.\n\r", ch);
        return;
    }
    
    if ( linkdead->desc != NULL )
    {
        send_to_char( "They aren't linkdead just use disconnect instead.\n\r", ch );
        return;
    }

    else
    {
        do_function( linkdead, &do_quit, "" );
        send_to_char("They have been booted.\n\r", ch);
        return;
    }

}


Then just add the declarations into interp.c, and interp.h and you should be good to go.
