BZFS Command Line Options
BZFS supports a number of command line options that let you set the various modes and parameters for the game.
Contents
Use
Any command line option can be passed to BZFS in the command line, or placed in a text file passed in with the -conf parameter.
Config files
A config file is simply a text file with a list of command line options, one per line. This file can be the parameter to the -conf command line option. BZFS will load all options in the config file as if they had been passed in as runtime options.
The Options
- -a linear angular
Sets the maximum linear and angular accelerations. The units are somewhat arbitrary so you'll have to experiment to find suitable values. Positive values will set limits to the acceleration and lower they are, greater is the inertia. Zero or negative values disable acceleration limits. -a 50 38 is recommended for standard-speed servers.
- -admsg message
Define a message which will be broadcast to all players every 15 minutes. This option can be used multiple times to define a multi-line message.
- -advertise groupname,groupname,...
Allows control of who can see this server on the server list. Use -advertise NONE to make a private server (no one will see the server, but global logins can be used). The default, if -advertise is not specified, is to allow everyone to see the server. Otherwise, your server will only be listed to members of the groups which you specify with -advertise.
- -autoTeam
Instructs the server to automatically assign joining players to the team that needs more players, overriding user preference. For specifics on operation, see Auto Team.
- -b
When -c is supplied, this option randomly rotates the buildings.
- -ban ip{,ip}*
Prohibits connections from the listed IP addresses. Trailing 255 bytes are treated as mask bytes.
- -banfile filename
Specifies the name of a file where bzfs will store the banlist. It will load the banlist from this file when it starts (if the file exists), and write the banlist back to the file when someone gets banned or unbanned. If this option isn't given the banlist will not be saved.
- -banTime
Default number of minutes player should be banned (unspecified, the default is 300).
- -c
Enables the capture-the-flag style game. By default this allocates one team flag per team. This can be modified see +f team. By default, the free-for-all style is used.
- -cache worldCacheURL
Specifies the URL for the world cache file. This is a binary file that clients will attempt to download before getting the world from the bzfs server.
- -cacheout filename
Save the currently specified world into a binary cache file and exit.
- -conf configfilename
Specifies the name of a configuration file to be used to set all of the bzfs options, rather than setting them on the command line.
- -cr
Enables the capture-the-flag style game with random map. You can optionally specify a building density by providing a number (default is 5). One team flag per team is provided, but more can be added through +f team. By default, the free-for-all style is used.
- -d
Increase debugging level. If more -d is given, more debugging info is obtained.
- -density num
Specify density for buildings, i.e. the higher the integer number, the more buildings you will get. This applies to automatically generated maps only.
- -disableBots
Prevent clients from using the ROGER autopilot or from using robots.
- +f {good|bad|teamflag-id}[{count}]
Forces the existence of the given flag. If specified multiple times for the same flag-id, then that many flags will appear. The good argument is equivalent to specifying +f once for each kind of good flag. Same goes for the bad argument. The teamflag-id must match one of the predefined Flag Codes.
- -f {flag-id}
Restricts a certain flag from existing.
- -fb
Allow flags on box buildings.
- -filterCallsigns
Turn on the filtering of callsigns and email addresses. Callsigns and addresses are compared against bad words provided via -badwords.
- -filterChat
Turn on the filtering of chat messages. Messages that contain words listed via a -badwords file are replaced with !@#$%^&* characters.
- -filterSimple
By default, all filtering is aggressive, matching much more than what is strictly listed in a -badwords file for convenience. Providing this option will make the -filterCallsigns and -filterChat comparisons exact match only.
- -g
Quit after serving one game.
- -groupdb file
Load groups from file
- -h
Buildings are given random heights.
- -handicap
Players are given a handicap advantage based on their ability in relation to the other players. Handicapped players will have faster tanks and shots. The handicap is determined by the player's score in relation to other players.
- -help
Shows a help page and lists all the valid flag id's.
- -helpmsg file name
Create a help message accessible by /help name, which prints the contents of file. Restricted to 10 lines per help message.
- -i interface
Server will listen for and respond to pings (sent via broadcast) on the given interface. Clients use this to find active servers on the network. This is the TCP/UDP/IP address the server will listen on.
- -j
Allows jumping.
- -lagdrop warn-count
Kicks players after warn-count lag warnings.
- -lagwarn time/ms
Send warnings to players that lag more than time.
- -loadplugin /filename
[[1]]
- -mp total | rogue,red,green,blue,purple,observer
Sets the maximum number of players, total or per team.A single value sets the total number of players allowed. Five comma separated values set the maximum for each team. If a count is left blank then no limit is set for that team, except for the limit on the total number of players. Both forms may be provided.
- -mps max-score
Sets a maximum score for individual players. The first player to reach this score is declared the winner and the game is over.
- -ms shots
Allows up to shots simultaneous shots for each player. This is 1 by default.
- -mts max-score
Sets a maximum score for teams. The first team to reach this score is declared the winner and the game is over.
- -noMasterBanlist
Server will not attempt to load the Master Ban list from the internet.
- -p port
Listen for game connections on port instead of the default port.Use -help to print the default port, or use -d debug printing.
- -passdb file
Load passwords from file
- -passwd password
Specify a server administrator password for use in remote administration such as /kick, /ban, /mute, etc messages.
- -pidfile filename
Specify a file where the server will write its process ID so it may be used for remote administration.
- -poll variable=value
Configure several aspects of the in-game polling system.
- -public
Causes the server to register itself with a list server, which clients can query to get a list of bzfs servers. By default, a server will respond to broadcast queries, allowing clients to find servers running on the standard port on the local subnet.
- -publicaddr address[:port]
Advertise this server with the given address and port. Only has an effect when used with -public. Normally a server advertises itself at the local address and port. Some servers are not accessible from the internet at this address (for example servers behind a firewall using Network Address Translation). Use this option to specify the address and/or port that internet users should use to access this server.
- -publiclist url
Advertise this server on the list servers listed at url. Only has an effect when used with -public. A built-in url is used by default. The BZFlag clients use the same built-in url so, by default, clients will see public servers automatically. This argument may be provided multiple times to publicize a server to multiple list servers.
- -q
If specified, the server will not listen for nor respond to ``pings. BZFlag sends out these pings to give the user a list of available servers.This effectively makes the server private, especially if the -p option is also used.
- +r
Makes most shots ricochet. Super bullets, shock waves, and guided missiles do not.
- -rabbit [score|killer|random]
Enables the rabbit-hunt style game. By default, the free-for-all style is used. You must specify the algorithm used to pick a new rabbit when the old one dies. The score algorithm uses a modified wins/(wins+losses) score and picks the top scoring player to be the new rabbit. The killer algorithm specifies a reverse tag game where whomever kills the rabbit becomes the new rabbit. The random algorithm randomly picks a new rabbit without regard to score. (The score algorithm is the original behavior.)
- -recbuf size
Start with the recording buffer active, with the specified size (in megabytes).
- -recbufonly
Disable recording straight to files
- -recdir directory
Specify the directory for record and replay files.
- -replay
Start the server in replay mode.
- -reportfile filename

- -reportpipe command
Enable the /report command and execute command when a report is filed. This can be used together with, or instead of the -reportfile option.
- -requireudp
Require clients to use parallel UDP. If players fire before opening a UDP channel, kick them off the server.
- +s num-flags
The server will have an extra num-flags random super flags available at all times. The -f option can be used to restrict which types of flags will be added. Required flags given by the +f option are not included in the num-flags total.
- -s num-flags
The server will have up to num-flags random super flags available at any time.The -f option can be used to restrict which types of flags will be added. Required flags given by the +f option are not included in the num-flags total.
- -sa
Antidote flags are provided for players with bad flags.
- -sb
Allow spawns on box buildings.
- -set name value

- -srvmsg message
Define a server welcome message. This option can be used multiple times to define a multiline message.
- -st time
Bad flags are automatically dropped after time seconds.
- -sw count
Bad flags are automatically dropped after count wins. Capturing a team flag does not count as a win.
- -synctime
Forces all clients to use the same time of day.T he current time is determined by the server's clock. This disables the + and - keys on the clients.
- -t
Adds teleporters to the game.
- -timemanual
The countdown has to be started manually using the /countdown command. This is useful for matches.
