# `reth debug` Various debug routines ```bash $ reth debug --help Usage: reth debug [OPTIONS] Commands: execution Debug the roundtrip execution of blocks as well as the generated data merkle Debug the clean & incremental state root calculations in-memory-merkle Debug in-memory state root calculation build-block Debug block building help Print this message or the help of the given subcommand(s) Options: --chain The chain this node is running. Possible values are either a built-in chain or the path to a chain specification file. Built-in chains: mainnet, sepolia, goerli, holesky, dev [default: mainnet] --instance Add a new instance of a node. Configures the ports of the node to avoid conflicts with the defaults. This is useful for running multiple nodes on the same machine. Max number of instances is 200. It is chosen in a way so that it's not possible to have port numbers that conflict with each other. Changes to the following port numbers: - DISCOVERY_PORT: default + `instance` - 1 - AUTH_PORT: default + `instance` * 100 - 100 - HTTP_RPC_PORT: default - `instance` + 1 - WS_RPC_PORT: default + `instance` * 2 - 2 [default: 1] -h, --help Print help (see a summary with '-h') Logging: --log.file.directory The path to put log files in [default: /reth/logs] --log.file.max-size The maximum size (in MB) of one log file [default: 200] --log.file.max-files The maximum amount of log files that will be stored. If set to 0, background file logging is disabled [default: 5] --log.file.filter The filter to use for logs written to the log file [default: debug] --log.journald Write logs to journald --log.journald.filter The filter to use for logs written to journald [default: error] --color Sets whether or not the formatter emits ANSI terminal escape codes for colors and other text formatting [default: always] Possible values: - always: Colors on - auto: Colors on - never: Colors off Display: -v, --verbosity...
