# `reth db`

Database debugging utilities

```bash
$ reth db --help

Usage: reth db [OPTIONS] <COMMAND>

Commands:
  stats    Lists all the tables, their entry count and their size
  list     Lists the contents of a table
  diff     Create a diff between two database tables or two entire databases
  get      Gets the content of a table for the given key

Options:
      --datadir <DATA_DIR>
          The path to the data dir for all reth files and subdirectories.
          
          Defaults to the OS-specific data directory:
          
          - Linux: `$XDG_DATA_HOME/reth/` or `$HOME/.local/share/reth/`
          - Windows: `{FOLDERID_RoamingAppData}/reth/`
          - macOS: `$HOME/Library/Application Support/reth/`
          
          [default: default]

      --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
          - goerli
          - sepolia
          - holesky
          
          [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]
