dCmd

dCmd is a term used in several software projects to denote a command dispatch utility or framework. It is not a single standard, but a name applied to different implementations that focus on issuing, routing, and managing commands across software components.

Common meanings include:

- A command-line distributed executor: a CLI tool that runs shell commands on remote hosts, aggregates output, and supports parallel execution, retry logic, and structured results.

- A CLI framework library: a toolkit for building subcommand-based command-line interfaces with command parsing, help generation, and plugin support.

- A command dispatch protocol: a lightweight API or protocol enabling devices or services to receive, execute, and report back results.

Origins and usage:

The term arose independently in multiple projects across the software ecosystem, and there is no universal specification; its exact meaning depends on the project. In practice, dCmd offerings tend to focus on centralizing command issuance, tracking results, and enabling automation workflows.

Design and features:

- Cross-platform support and language-agnostic interface design.

- Secure authentication, audit logging, and access control.

- Plugin architecture for extending command definitions and behavior.

- Standardized output formats (often JSON) with options for streaming or incremental results.

Typical applications:

DevOps task automation, remote system administration, IoT device orchestration, and data processing pipeline management.

Implementation notes:

Common implementations are in Python, Go, or Rust; communications may use SSH, TLS, or other secure channels. Emphasis is often on idempotent command execution, robust error handling, and clear, structured reporting of outcomes.
