How to Configure Ducksh: Themes, Aliases, and Shell Settings

Ducksh documents a compact setup using ~/.quackrc, aliases, exported variables, and theme commands. Prompt customization and integrations with other shells are not documented.

Ducksh’s documented setup is intentionally simple: put user settings in ~/.quackrc, use alias for shortcuts, export for environment variables, and theme to switch themes. The available instructions do not explain prompt customization or integration with Bash, Zsh, Fish, or other shells, so those capabilities should not be assumed.

Where Ducksh keeps its configuration

Ducksh uses ~/.quackrc as its user configuration file. The introductory guide describes a small set of commands rather than a larger settings schema or documented precedence rules. See the Ducksh project guide for its configuration overview.

To load a Ducksh configuration file, the guide lists source FILE. It also lists reset, which clears the terminal and reloads ~/.quackrc.

Set aliases and environment variables

Create an alias

Use the documented form alias NAME=CMD to define a shortcut. Replace NAME with the alias and CMD with the command it should run. The guide does not specify additional quoting or argument-handling rules.

Export an environment variable

Set a variable with export A=value, substituting the variable name and desired value. The quick reference also lists path to show PATH entries.

Switch Ducksh themes

Run theme with no name to list themes, or use theme NAME to switch to a named theme. The guide does not identify the available theme names, describe a theme-file format, or say whether themes control prompt styling.

What is documented about prompts

The guide says command history appears in the prompt: use the up and down arrows to browse prior commands and the right arrow to accept a history suggestion. These are history interactions, not evidence of a prompt-customization setting. No prompt customization procedure or configuration option is documented.

Shell integrations: what the guide does and does not establish

Ducksh’s source FILE command loads a Ducksh configuration file. The guide does not document using it to load Bash, Zsh, Fish, or another shell’s configuration, and it does not describe integrations with those shells. Treat Ducksh configuration loading as distinct from cross-shell integration unless project documentation confirms otherwise.

The project guide points users to its SourceForge repository and instructs them to download Ducksh and run the included installer. It does not state a version number, supported operating systems, prerequisites, or troubleshooting steps. See the Ducksh SourceForge project page.

  1. Download Ducksh from the SourceForge project.
  2. Run ./install.sh from the downloaded project files.
