DESCRIPTION

       Freeciv  is  a free turn-based multiplayer strategy game, in which each player becomes the
       leader of a civilization, fighting to obtain the ultimate goal:  To  become  the  greatest
       civilization.

       Players  of  Civilization II® by Microprose® should feel at home, since one aim of Freeciv
       is to have compatible rules.

       Freeciv is maintained by an international team of coders and enthusiasts,  and  is  easily
       one of the most fun and addictive network games out there!

       This  is  the  client  program  used  to  connect  to a Freeciv server - see also freeciv-
       server(6) . freeciv-gtk3, freeciv-gtk3.22, freeciv-gtk4, freeciv-qt, and freeciv-sdl2  can
       also spawn their own local server for single-player games.

       This  manual  page  only  lists  the  command line arguments. For more details about using
       freeciv-gtk3, freeciv-gtk3.22, freeciv-gtk4, freeciv-sdl2, or freeciv-qt, see  the  Client
       Manual which can be found at the Freeciv website ⟨https://www.freeciv.org/⟩ as well as the
       documentation which is part of the Freeciv distribution.

OPTIONS

       The following options are accepted by all clients. They may not be combined; that is, "-np
       caesar  5557"  will  not  work,  instead  you would need to enter "-n caesar -p 5557". All
       options have a short form (single hyphen and single letter) and a long form (double hyphen
       and a complete word); their effects are identical.

       -A protocol, --Announce protocol
              Uses protocol when searching for games on a LAN.  Possible values for protocol are:

              IPv4

              IPv6

              none

       -a, --autoconnect
              Skips the connect dialog, automatically inserting the default values. This is quite
              convenient when all has been set up properly.

       -d level, --debug level
              Sets the amount of debugging information to be logged in the file named by  the  -l
              option. Acceptable values for the level are:

              fatal     for fatal messages only.

              error     for fatal and error messages.

              warning   for fatal, error and warning messages

              normal    for fatal, error, warning and normal messages (default).

              verbose   for fatal, error, warning, normal, and verbose messages.

       -F [ signal_number ], --Fatal [ signal_number ]
              Raise a custom signal on failed assertion.  If signal_number is not specified, then
              the ABRT signal will be used.

       -f filename, --file filename
              Loads a saved game file (filename). This is for reloading previously  saved  games,
              or for starting scenarios from the command line.

       -h, --help
              Prints a short summary of the standard command line options.

       -l filename, --log filename
              Defines  a  log file, filename, to be produced during processing. Use the -d option
              to set how much is logged.  By default, fatal, error, warning, and normal  messages
              are  printed  to  standard  output.   With  a log file, such messages go to the log
              instead.  If filename already exists, it is appended to.

       -M URL, --Meta URL
              Specifies the URL of the metaserver to connect to. A metaserver is  a  place  where
              Freeciv  servers can publish their presence. Freeciv clients consult the metaserver
              to offer users a selection of games to join. By default,  the  standard  metaserver
              run by the Freeciv maintainers will be used.

       -n name, --name name
              Specifies  the  user  name  (name)  to use to connect to the server. This option is
              critical when reconnecting to a game. Please note that you might need to quote your
              username.

       -p port, --port port
              Specifies  the  server port to connect to. By default this is 5556, if in doubt ask
              the server administrator.

       -P string, --Plugin string
              Specifies the plugin to use for sound output.  Available options  for string are:

              none

              sdl

       -r filename, --read filename
              Specifies a file, filename, of server commands which a server spawned by the client
              will  automatically  read  and process, as if you had typed them in at the server's
              prompt.

       -s address, --server address
              Specifies the game server address to connect to. This server might  easily  run  on
              the same machine as the client.

       -S name, --Sound name
              Specifies the sound set to use. A file called name.soundspec is searched for in the
              usual places (see the FILES section).

       -t name, --tiles name
              Specifies the map graphics ("tiles") to be used within  the  game.  A  file  called
              name.tilespec  is  searched  for  in  the  usual  places  (see  the FILES section).
              Currently the following tilespecs are distributed with Freeciv:

              • amplio2.tilespeccimpletoon.tilespechex2t.tilespecisophex.tilespecisotrident.tilespectrident.tilespec

       -v, --version
              Prints the version number and exits.

       --     All parameters following this -- will be considered as client-specific parameters.

       -- -f, -- --fullscreen
              Starts the client in full  screen  mode.   Only  implemented  in  the  freeciv-sdl2
              client.

       -- -h, -- --help
              Print the client-specific parameter help.

       -- -r WIDTHxHEIGHT, -- --resolution WIDTHxHEIGHT
              Behave  as if screen resolution were WIDTHxHEIGHT. Only implemented in the freeciv-
              gtk3, freeciv-gtk3.22, and freeciv-gtk4 clients.

       -- -t theme, -- --theme theme
              Use a particular GUI theme. Only implemented in the freeciv-sdl2 client.

EXAMPLES

       freeciv-gtk3 --name "King Richard" --server io.daimi.aau.dk
              Starts the GTK3 client using the name King Richard and connecting to the server  at
              io.daimi.aau.dk.

       freeciv-sdl2 -a -t trident
              Starts the SDL2-client with the trident tiles and autoconnects to localhost.

FILES

       ~/.freeciv/freeciv-client-rc-[version-number]
              This is where your local settings will be stored.

       tilespecs
              These are searched for in the data path; see ENVIRONMENT.

       soundspecs
              These are searched for in the data path; see ENVIRONMENT.

       The  freeciv-modpack(6) utility can be used to locate and download additional content such
       as tilesets and soundsets and (for client-spawned servers only) scenarios and rulesets; it
       saves files under ~/.freeciv .

ENVIRONMENT

       The Freeciv client accepts these environment variables:

       FREECIV_CAPS
              A  string containing a list of "capabilities" provided by the server. The compiled-
              in default should be correct for most purposes, but if you are  familiar  with  the
              capability  facility  in  the  source  you  may  use it to enforce some constraints
              between clients and server.

       FREECIV_COMPRESSION_LEVEL
              Sets the compression level for network traffic.

       FREECIV_DATA_ENCODING
              Sets the character encoding used for data files, savegames, and  network  strings).
              This  should  not  normally be changed from the default of UTF-8, since that is the
              format of the supplied rulesets and the standard network protocol.

       FREECIV_INTERNAL_ENCODING
              Sets the character encoding used internally by the freeciv client.  This  generally
              needs to match the GUI toolkit, so its default depends on the specific client; most
              clients default to UTF-8.

       FREECIV_LOCAL_ENCODING
              Sets the local character encoding (used for the command line and terminal  output).
              The default is inferred from other aspects of the environment.

       FREECIV_MULTICAST_GROUP
              Sets the multicast group (for the LAN tab).

       FREECIV_DATA_PATH
              A  colon separated list of directories pointing to the freeciv data directories. By
              default Freeciv looks in the following directories, in order, for any  data  files:
              the  current  directory;  the  "data"  subdirectory  of  the current directory; the
              subdirectory ".freeciv/3.1" in the user's home directory; and the  directory  where
              the  files  are  placed by running "make install".  If not set, FREECIV_SAVE_PATH A
              colon separated list of directories pointing to the freeciv  save  directories.  By
              default  Freeciv  looks in the following directories, in order, for save files: the
              current directory;  and  the  subdirectory  ".freeciv/saves"  in  the  user's  home
              directory.

              (This  does  not  affect  where  the server spawned by the client creates save game
              files; these are always created in ".freeciv/saves" in the user's home directory.)

       FREECIV_SCENARIO_PATH
              A colon separated list of directories pointing to the freeciv scenario directories.
              By  default  Freeciv  looks  in  the  following directories, in order, for scenario
              files: the current directory; the  "data/scenarios"  subdirectory  of  the  current
              directory;     the     subdirectories     ".freeciv/3.1/scenarios"     and     then
              ".freeciv/scenarios" in the user's home directory;  and  the  directory  where  the
              files are placed by running "make install".

              (This  does  not  affect  where  the  server spawned by the client creates scenario
              files; these  are  always  created  in  ".freeciv/scenarios"  in  the  user's  home
              directory.)

       FREECIV_OPT
              Specifies  a  file to contain local settings, instead of ~/.freeciv/freeciv-client-
              rc-[version-number].

       HOME   Specifies the user's home directory.

       http_proxy
              Set this variable accordingly when using a proxy.

       LANG  or  LANGUAGE
              Sets the language and locale on some platforms.

       LC_ALL  or  LC_CTYPE
              Similar to LANG (see documentation for your system).

       USER   Specifies the username of the current user.
