CLI Reference


What’s in This Guide?

The CLI Reference Guide contains at-a-glance information about using the Fugue CLI, including description, options, usage, and examples for each CLI command.

For information about CLI logging, see Logging. For background information on how Fugue works, see the User Guide.

What’s the Fugue CLI?

The Fugue software has two components:

  • The Fugue CLI, which runs locally, on your machine
  • The Fugue Conductor, which runs remotely, in AWS

As the front end of the system, the CLI is where you enter commands. The Conductor is the back end, or what handles the commands. You use the CLI to tell the Conductor what to do, such as creating, modifying, or destroying infrastructure.

Options Without Commands

The fugue executable accepts the following options without a command:


Display the version of internal components packaged with the CLI:

  • The Fugue CLI itself
  • Vars, Fugue’s distributed variable service
  • lwc, the Ludwig compiler
  • lwdoc, an internal documentation tool
-h | --help
Show help text. The help flag is available throughout the CLI in both global and command-specific contexts. In this use (fugue -h) it provides basic help and an overview of commands. When used following a command (fugue init -h), it displays help text for that specific command.

Global Options Preceding Commands

The fugue executable accepts the following options preceding any command:

-v | --verbose
Be verbose. The verbose flag displays command output in verbose mode, providing additional information for a number of Fugue CLI commands. Within Fugue, verbose output describes AWS API calls and responses.
Use color output. This is expected to work on OSX and Linux terminals. Results may vary on Windows platforms.
