Commands

Unofficial LFS commands website: https://lfs-commands.vercel.app/

Command line options

LFS can be started using a command line or another program.

Before selecting host options, you may find it helpful to run LFS and try out the options on the Start New Host screen - the required upload bandwidth for those options is displayed on screen.

A command line or a command file is required for dedicated hosts.

The following command, if used, must be the first command on a command line or the first command in a command file.

/settings=X.txt - load settings from X.txt instead of cfg.txt

If the following command is used it must be before any other commands.

/join=Host Name - join an internet server

The following command may only be used after /join.

/pass=Pass - if required - password

The following commands are mainly for hosts but may also be used to override various cfg.txt settings or start InSim.

Command	Description	Example
/ip=X.X.X.X	if required - local specified IP address	/ip=192.168.1.1

/mprdir=X	set the data folder for saving multiplayer replays	/mprdir=multi
/lytdir=X	set the data folder for autocross layouts	/lytdir=my_layouts

You can use a command file xxx.txt instead of a long command line.
The command file contains the command line parameters.
The parameters can be spread onto several lines.
The command file can contain comments, starting with two slashes //.

Then the command line would be simply:

LFS.exe /cfg=xxx.txt (where xxx.txt is the name of the config file)

Host commands

Some text commands are intended for hosts and administrators.

Using the normal text message system (pressing T in a normal host or typing into the virtual console at the host management web interface: https://www.lfs.net/hosting/admin), the message becomes a command if you start it with a slash character (/). For most commands with parameters, you can retrieve their current status by omitting the parameter (for example /rstend feeds back the currently active setting).

/cars=TBO+LX4        :allow XRT, RB4, FXO and LX4
/cars=ROAD-UF1       :allow all road cars except the UF 1000
/cars+=XRT           :add XRT to the current list of cars

Multiple commands on single line

Multiple commands can be added on a single line which sometimes can avoid the need for a script file, e.g. to set a button to change tyres in pit stop, you could use a double command:

/pitins ftyre super /pitins rtyre super

NOTE: some commands cannot be followed by another command:

/say /echo /join /rcm /pass /msg /altf /ctrlf

LFS World info

You can retrieve LFS World info and statistics from in-game as well, by using the following text commands.
