Players of Civilization II(R) by Microprose(R) should feel at home, since one aim of Freeciv is to have compatible rules. Freeciv is maintained by an international team of coders and enthusi- asts, 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-gtk3.22, freeciv-gtk4, freeciv-qt, freeciv-sdl2, and freeciv-sdl3 can also spawn their own local server for single-player games. This manual page only lists the command line arguments. For more de- tails about using freeciv-gtk3.22, freeciv-gtk4, freeciv-sdl2, freeciv- sdl3, 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 com- bined; 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 hy- phen 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 val- ues 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 prop- erly. -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 (de- fault). verbose for fatal, error, warning, normal, and verbose mes- sages. -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 previ- ously 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 out- put. 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 selec- tion 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. -- -f, -- --fullscreen Starts the client in full screen mode. Only implemented in the freeciv-sdl2 and freeciv-sdl3 clients. -- -h, -- --help Print the client-specific parameter help. -- -r WIDTHxHEIGHT, -- --resolution WIDTHxHEIGHT Behave as if screen resolution were WIDTHxHEIGHT. Only imple- mented in the freeciv-gtk3.22 and freeiv-gtk4 clients. -- -t theme, -- --theme theme Use a particular GUI theme. Only implemented in the freeciv-sdl2 and freeciv-sdl3 clients. EXAMPLES freeciv-gtk3.22 --name "King Richard" --server io.daimi.aau.dk Starts the GTK3.22 client using the name King Richard and con- necting to the server at io.daimi.aau.dk. freeciv-sdl3 -a -t trident Starts the SDL3-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 addi- tional 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 pur- poses, 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 rule- sets 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 di- rectories, in order, for any data files: the current directory; the "data" subdirectory of the current directory; the subdirec- tory ".freeciv/3.2" in the user's home directory; and the direc- tory 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 direc- tory; the "data/scenarios" subdirectory of the current direc- tory; the subdirectories ".freeciv/3.2/scenarios" and then ".freeciv/scenarios" in the user's home directory; and the di- rectory 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.
