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, freeciv-gtk3.22, 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-gtk2, freeciv-gtk3, freeciv-gtk3.22, freeciv-sdl2, or freeciv-qt, see the Client Manual which can be found at the Freeciv website 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.

Uses protocol when searching for games on a LAN. Possible values for protocol are:

IPv4

IPv6

none

Skips the connect dialog, automatically inserting the default values. This is quite convenient when all has been set up properly.
Sets the amount of debugging information to be logged in the file named by the -l option. Acceptable values for the level_number are:

fatal for fatal messages only.

error for fatal and error messages.

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

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

Raise a custom signal on failed assertion. If signal_number is not specified, then the ABRT signal will be used.
Loads a saved game file (filename). This is for reloading previously saved games, or for starting scenarios from the command line.
Prints a short summary of the standard command line options.
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. If filename already exists, it is appended to.
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.
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.
Specifies the server port to connect to. By default this is 5556, if in doubt ask the server administrator.
Specifies the plugin to use for sound output. Available options for string are:

none

sdl

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.
Specifies the game server address to connect to. This server might easily run on the same machine as the client.
Specifies the sound set to use. A file called name.soundspec is searched for in the usual places (see the FILES section).
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

Prints the version number and exits.
--
All parameters following this -- will be considered as client-specific parameters.
Starts the client in full screen mode. Only implemented in the freeciv-sdl2 client.
Print the client-specific parameter help.
Behave as if screen resolution were WIDTHxHEIGHT. Only implemented in the freeciv-gtk3 and freeciv-gtk3.22 clients.
Use a particular GUI theme. Only implemented in the freeciv-sdl2 client.

EXAMPLES

Starts the GTK3 client using the name King Richard and connecting to the server at io.daimi.aau.dk.
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.
These are searched for in the data path; see ENVIRONMENT.
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:

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.
Sets the compression level for network traffic.
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.
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.
Sets the local character encoding (used for the command line and terminal output). The default is inferred from other aspects of the environment.
Sets the multicast group (for the LAN tab).
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/3.0" 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.)

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/3.0/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.)

Specifies a file to contain local settings, instead of ~/.freeciv/freeciv-client-rc-[version-number].
Specifies the user's home directory.
Set this variable accordingly when using a proxy.
Sets the language and locale on some platforms.
Similar to LANG (see documentation for your system).
Specifies the username of the current user.
