    For example, if you ask {% data variables.product.prodname_copilot_short %} to create a bash script but you do not want to use the script {% data variables.product.prodname_copilot_short %} suggests, you can stop the current operation and enter a new prompt, such as: `Continue the previous task but include usage instructions in the script`.
 
+## CLI parameters

+
+
+| Parameter | Description | Example |

+| `-p "<text>"` or `--prompt "<text>"` | Provide a prompt non-interactively (non-interactive mode exits after completion). | `copilot -p "Run tests and fix failures"` |
+| `-i "<text>"` or `--interactive "<text>"` | Start interactive mode and automatically execute a prompt. | `copilot -i "Fix the bug in main.js"` |

 ## Permissions
 
 {% data variables.copilot.copilot_cli_short %} uses a permissions system to control access to paths and URLs. At times, path and URL permission checks utilize heuristic-based detection, which has limitations to be aware of.
