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-
       gtk2, freeciv-gtk3, and freeciv-sdl 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-gtk2,
       freeciv-gtk3,  freeciv-sdl,  or  freeciv-xaw,  see  the  Client  Manual which can be found at the Freeciv
       website ⟨http://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_number, --debug level_number
Sets the amount of debugging information to be logged in the file named by the -l option.
Acceptable values for the level_number are:

0 for fatal messages only.

1 for fatal and error messages.

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

3 for fatal, error, 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.

-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, and normal messages are printed to standard output. With a
log file, such messages go to the log instead.

-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.tilespec

• cimpletoon.tilespec

• hex2t.tilespec

• isophex.tilespec

• isotrident.tilespec

• trident.tilespec

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

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

-- -e, -- --eventthread
Initializes the event subsystem in other thread. Only available for the freeciv-sdl client under
Linux or BeOS.

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

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

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

EXAMPLES

       freeciv-gtk2 --name "King Richard" --server io.daimi.aau.dk
              Starts  the  GTK2  client  using  the  name  King  Richard  and  connecting  to  the   server   at
              io.daimi.aau.dk.

       freeciv-sdl -a -t trident
              Starts the SDL client with the trident tiles and autoconnects to localhost.

FILES

       ~/.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 data encoding (used for data files, savegames, and network strings).

FREECIV_INTERNAL_ENCODING
Sets the internal encoding (used for GUI strings).

FREECIV_LOCAL_ENCODING
Sets the local encoding (used for terminal output).

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/2.4" in the user's home
directory; and the directory where the files are placed by running "make install". If not set,
FREECIV_PATH is checked before these defaults are used.

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. If not set, FREECIV_PATH is checked
before these defaults are used; in this case Freeciv also looks in "saves" potential
subdirectories.

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/2.4/scenarios" and then ".freeciv/scenarios" in the user's home directory; and the
directory where the files are placed by running "make install". If not set, FREECIV_PATH is
checked before these defaults are used; in this case Freeciv also looks in "scenario" and
"scenarios" potential subdirectories.

FREECIV_PATH
A colon separated list of directories to look for various files. This variable has no effect if
FREECIV_DATA_PATH, FREECIV_SAVE_PATH and FREECIV_SCENARIO_PATH are defined together; those
variables are the recommended way to override paths, with FREECIV_PATH provided for backward
compatibility with older versions of Freeciv. The precise search path depends on the type of file
being searched for.

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.
