       This  manpage  was  originally  put together by Florian Ernst <florian_ernst AT gmx.net> using the Client
       Manual and the comments in the sourcecode. It was updated by Ben Bettin <bwbettin AT  gmail.com>  to  add
       new  features,  integrate  information from the website's online documentation, and for slight formatting
       adjustments. Feel free to use it as you wish.

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 as well as the documentation which is part of the Freeciv distribution.

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.

Examples

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

       freeciv-sdl2-a-ttrident
              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 .

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.

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

IPv4IPv6none-a,--autoconnect
Skips the connect dialog, automatically inserting the default values. This is quite convenient
when all has been set up properly.

-dlevel,--debuglevel
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.

-ffilename,--filefilename
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.

-lfilename,--logfilename
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.

-MURL,--MetaURL
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.

-nname,--namename
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.

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

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

nonesdl-rfilename,--readfilename
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.

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

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

-tname,--tilesname
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 client.

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

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

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