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 ⟨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_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.

-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, 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.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.

-- -r WIDTHxHEIGHT, -- --resolution WIDTHxHEIGHT
Behave as if screen resolution were WIDTHxHEIGHT. Only implemented in the freeciv-
gtk3 and freeciv-gtk3.22 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/3.0" 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.)

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/3.0/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.)

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.
