## using TDengine CLI

TDengine CLI will display a welcome message and version information if it successfully connected to the TDengine service. If it fails, TDengine CLI will print an error message. See [FAQ](/train-faq/faq) to solve the problem of terminal connection failure to the server. The TDengine CLI prompts as follows:

```cmd

```

After entering the TDengine CLI, you can execute various SQL commands, including inserts, queries, or administrative commands. Please see the [official document](https://docs.tdengine.com/reference/taos-shell#execute-sql-script-file) for more details.
