# Pantheon Command Line
!!! important "Breaking Changes in v0.9"
In v0.9, the command line changed to improve usability. These are breaking changes; that is,
in many cases the v0.8 command line options no longer work.
This reference and the rest of the documentation has been updated to reflect these changes. The [release notes](https://github.com/PegaSysEng/pantheon/blob/master/CHANGELOG.md)
include a mapping of the previous command line options to the new options.
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
### accounts-whitelist
```bash tab="Syntax"
--accounts-whitelist[=<hex string of account public key>[,<hex string of account public key>...]...
```
```bash tab="Example"
--accounts-whitelist=[0xfe3b557e8fb62b89f4916b721be55ceb828dbd73, 0x627306090abaB3A6e1400e9345bC60c78a8BEf57]
```
Comma separated account public keys for permissioned transactions. You can specify an empty list.
!!!note
Permissioning is under development and will be available in v1.0.
### banned-node-ids
```bash tab="Syntax"
--banned-node-ids=<bannedNodeId>[,<bannedNodeId>...]...
```
```bash tab="Example Command Line"
--banned-nodeids=0xc35c3...d615f,0xf42c13...fc456
```
```bash tab="Example Configuration File"
banned-nodeids=["0xc35c3...d615f","0xf42c13...fc456"]
```
List of node IDs with which this node will not peer. The node ID is the public key of the node. You can specify the banned node IDs with or without the `0x` prefix.
!!!tip
The singular `--banned-node-id` and plural `--banned-node-ids` are available and are just two
names for the same option.
### bootnodes
```bash tab="Syntax"
--bootnodes[=<enode://id@host:port>[,<enode://id@host:port>...]...]
```
```bash tab="Example Command Line"
--bootnodes=enode://c35c3...d615f@1.2.3.4:30303,enode://f42c13...fc456@1.2.3.5:30303
```
```bash tab="Example Configuration File"
bootnodes=["enode://c35c3...d615f@1.2.3.4:30303","enode://f42c13...fc456@1.2.3.5:30303"]
```

an empty list of bootnodes is defined by default unless you define custom bootnodes as described in
[private network documentation](../Configuring-Pantheon/Testing-Developing-Nodes.md#bootnodes).
!!! note
Specifying that a node is a [bootnode](../Configuring-Pantheon/Testing-Developing-Nodes.md#bootnodes)
must be done on the command line using [`--bootnodes`](#bootnodes) option without value,
not in a [configuration file](../Configuring-Pantheon/Using-Configuration-File.md).

```
Comma-separated APIs to enable on the HTTP JSON-RPC channel.
When you use this option, the `--rpc-http-enabled` option must also be specified.
The available API options are: `ADMIN`, `ETH`, `NET`, `WEB3`, `CLIQUE`, `IBFT`, `DEBUG`, and `MINER`.
The default is: `ETH`, `NET`, `WEB3`.

```
```bash tab="Example Configuration File"

Specifies domain URLs for CORS validation.
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.
!!!tip
For development purposes, you can use `"all"` or `"*"` to accept requests from any domain,
but we don't recommend this for production code.
