+##### Option B: Scan Ansible inventory hosts.json
+
+If your shell does not support pipes, you can generate a `hosts.json` from the `ansible-inventory` command and then pass that file to `cnspec scan` using the `--inventory-file` flag.
+
+```bash title="Generate hosts.json and scan with cnspec scan command"
+ansible-inventory -i hosts.ini --list > hosts.json
+cnspec scan --inventory-file hosts.json --inventory-format-ansible
+```

 Generate a `hosts.json` file from the `ansible-inventory` command and then pass that file to `cnspec scan` using the `--inventory-file` flag.
 
 ```bash title="Generate hosts.json and scan with cnspec scan command"
 ansible-inventory -i hosts.ini --list > hosts.json
 
 cnspec scan --inventory-file hosts.json --inventory-format-ansible

 Both cnspec and the Mondoo Console show results from each policy that runs against your assets.
