install_system_commands(pre = "sys_") public

CommandProcessor.install_system_commands(pre)

      pre: String - command name prefix

defines every command which belongs in default_system_path via CommandProcessor.command(). It doesn’t define already defined methods twice. By default, "pre_" is prefixes to each method name. Characters that may not be used in a method name are all converted to ‘_’. Definition errors are just ignored.
