Command-line options

Run WorldLand

WorldLand is primarily controlled using the command line. WorldLand is started using the worldland command. Stop it by pressing ctrl-c.

./worldland <flags>

You can configure WorldLand using command line options (flags). WorldLand also has sub-commands that can invoke functions such as console or blockchain import/export.

As an alternative to passing the numerous flags to the worldland binary, you can also pass a configuration file via:

$ ./worldland <other flags> --config /path/to/your_config.toml

Config File

To get an idea of how the file should look, you can use the dumpconfig sub-command to export your existing configuration:

$ ./worldland <other flags> dumpconfig >> CONFIG_DIR

Example:

$ ./worldland <other flags> -gwangju dumpconfig -datadir /home/worldland/gwangju >> config.toml

Return:

config. toml
