# Pantheon Command Line

!!! important "Breaking Changes in v0.9"
    In v0.9, changes will be made to the command line options to improve usability. These will be breaking changes; that is, 
    in many cases the v0.8 command line options will no longer work. This reference and the rest of the documentation will be 
    updated to reflect these changes. Any further information required about the changes will be included in the v0.9 release notes. 

This reference describes the syntax of the Pantheon Command Line Interface (CLI) options and subcommands.

```bash
pantheon [OPTIONS] [COMMAND]
```

Runs the Pantheon Ethereum full node client.

!!!tip
    Use a [configuration file](../Configuring-Pantheon/Using-Configuration-File.md) to save the command line options in a file.

## Options

The default is `none`.

!!!note
    This option is not used when running Pantheon from the [Docker image](../Getting-Started/Run-Docker-Image.md#custom-configuration-file) or in a [configuration file](../Configuring-Pantheon/Using-Configuration-File.md).

--datadir=/home/me/me_node
```

```bash tab="Example Configuration File"

The path to the Pantheon data directory. The default is the `/build/distributions/pantheon-<version>` directory in the Pantheon installation directory.

!!!note
    This option is not used when running Pantheon from the [Docker image](../Getting-Started/Run-Docker-Image.md#persisting-data). 


### dev-mode

```bash tab="Syntax"
--dev-mode
```

```bash tab="Example Configuration File"
dev-mode=true
```
  
Set this option to `true` to run in development mode. 
For example, specify this option to perform CPU mining more easily in a private test network. 
In development mode, a custom genesis configuration specifies the chain ID. 
When using this option, also set the [`--network-id`](#network-id) option to the network you use for development.
Default is `false`.
  
  
!!!note
    The [`--dev-mode`](#dev-mode) option overrides the [`--genesis`](#genesis) option. If both are specified, the development mode configuration is used.  


### genesis

Domain URLs must be enclosed in double quotes and comma-separated.

Listed domains will be allowed access to node data (whitelisted).
If your client interacts with Pantheon using a browser app (such as Remix using a direct connection or a block explorer), 
you must whitelist the client domains. 

The default value is `"none"`.
If you don't whitelist any domains, you won't be able to use webapps to interact with your Pantheon node.

!!!note
    MetaMask runs as native code so does not require CORS validation.
    If Remix is connecting to the node through MetaMask, it also does not require CORS validation.

    For development purposes, you can use `"all"` to accept requests from any domain, but we don't recommend this for production code.
