README single transformation command fails

[Toroi01]

Describe the issue

The generated README for projects created with databricks bundle init default-python contains an outdated command for running a single task.

The README at src/my_project_etl/README.md suggests:

databricks bundle run my_project_etl --select sample_trips_my_project

With Databricks CLI v0.299.2, this fails with:

Error: unknown flag: --select

It appears the --select flag is no longer supported (or was renamed), but the generated template documentation was not updated accordingly.

Steps to reproduce

1. Generate a new project:

   databricks bundle init default-python

2. Open src/my_project_etl/README.md

3. Run the documented command:

   databricks bundle run my_project_etl --select sample_trips_my_project

4. Observe the error:

   Error: unknown flag: --select
   

Expected behavior

The generated README should contain a command compatible with current Databricks CLI versions.

Actual behavior

The documented command fails because the CLI does not recognize the --select flag.

Environment

• Databricks CLI version: v0.299.2
• OS: WSL2 with Ubuntu 24.04.2 LTS

Regression

Unknown. I have only tested this behavior with Databricks CLI v0.299.2.

Additional context

I found that the following command works instead:

databricks bundle run my_project_etl --refresh sample_trips_my_project

Although I am not sure whether this is the intended replacement for --select.
