```
Xray is a platform for building proxies.

Usage:

        xray <command> [arguments]

The commands are:

        run          Run Xray with config, the default command
        version      Show current version of Xray
        api          Call an API in an Xray process
        tls          TLS tools
        uuid         Generate UUIDv4 or UUIDv5
        x25519       Generate key pair for x25519 key exchange
        wg           Generate key pair for wireguard key exchange

Use "xray help <command>" for more information about a command.

```
### xray run

Specify one or more configuration files and run.

Usage:

```
 xray run [-c config.json] [-confdir dir]
```

```
Run Xray with config, the default command.

The -config=file, -c=file flags set the config files for
Xray. Multiple assign is accepted.

The -confdir=dir flag sets a dir with multiple json config

Default "json".

The -test flag tells Xray to test config files only,
without launching the server
