This is the client program used to connect to a Freeciv server - See also freeciv-server(6)

This manual page only lists the command line arguments. For details regarding the options when using freeciv-gtk2 freeciv-sdl freeciv-xaw freeciv-win32 or freeciv-ftwl see the Client Manual which can be found at http://www.freeciv.org/ as well as the documentation which is part of the Freeciv distribution.

OPTIONS

All the Freeciv clients accept of the standard X Toolkit command line options along with the additional options listed below. Those 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, --announce protocol

Uses protocol when searching game from LAN. Possible values for protocol are:

IPv4

IPv6

Specifies the name (string) to play under. This option is critical when reconnecting to a game. Please note that you might need to quote your playername.

-S filename, --Sound filename

FILES

~/.freeciv-client-rc-[version-number]

This is where your local settings will be stored.

tilespecs

The Freeciv client requires several files in the Freeciv data directory, which is /usr/local/share/freeciv by default. Currently the following tilespecs can be used:

• amplio.tilespec

• hex2t.tilespec

• isophex.tilespec

• isotrident.tilespec

• trident.tilespec

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_PATH: A colon separated list of directories pointing to the freeciv data directory. 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" in the user's home directory; and the directory where the files are placed by running "make install".
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.
