# `reth test-vectors`

Generate Test Vectors

```bash
$ reth test-vectors --help

Usage: reth test-vectors [OPTIONS] <COMMAND>

Commands:
  tables  Generates test vectors for specified tables. If no table is specified, generate for all
  help    Print this message or the help of the given subcommand(s)

Options:
      --chain <CHAIN_OR_PATH>
          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 <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 <PATH>
          The path to put log files in
          
          [default: /reth/logs]

      --log.file.max-size <SIZE>
          The maximum size (in MB) of one log file
          
          [default: 200]

      --log.file.max-files <COUNT>
          The maximum amount of log files that will be stored. If set to 0, background file logging is disabled
          
          [default: 5]

      --log.file.filter <FILTER>
          The filter to use for logs written to the log file
          
          [default: debug]

      --log.journald
          Write logs to journald

      --log.journald.filter <FILTER>
          The filter to use for logs written to journald
          
          [default: error]

      --color <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...
          Set the minimum log level.
          
          -v      Errors
          -vv     Warnings
          -vvv    Info
          -vvvv   Debug
          -vvvvv  Traces (warning: very verbose!)

  -q, --quiet
          Silence all log output
```
