Serve and watch shell commands as Prefect flows.

Executes a shell command and observes it as Prefect flow.

Creates and serves a Prefect deployment that runs a specified shell command according to a cron schedule or ad hoc.

This function allows users to integrate shell command execution into Prefect workflows seamlessly. It provides options for scheduled execution via cron expressions, flow and deployment naming for better management, and the application of tags for easier categorization and filtering within the Prefect UI. Additionally, it supports streaming command output to Prefect logs, setting concurrency limits to control flow execution, and optionally running the deployment once for ad-hoc tasks.
