Thecommand-not-found module is a feedback provider plugin for PowerShell.This feedback provider depends on thecommand-not-found utility,which is often available on Linux by default,to provide suggestions when a native command cannot be found.

bash also calls thecommand-not-found utility to provide suggestions when a command cannot be found.But this feedback provider plugin does more than that,thanks to thecommand-line predictor feature in PowerShell.It also implements theICommandPredictor interface and serves as a predictor.When the resulted feedback contains actionable items, such as commands to run,they will be used as predictive suggestions to streamline the user's command-line experience.

Thecommand-not-found plugin is built on theIFeedbackProvider interface,which is available with PowerShell7.4.0-preview.2 or above.To display prediction suggestions from thecommand-not-found,you needPSReadLine 2.2.6 or above.

• PowerShell7.4.0-preview.2 or above
• PSReadLine2.2.6 or above

PowerShell feedback providers and predictors are written in C# and registered with the PowerShellSubsystem Plugin Model.To learn more, see "How to create a feedback provider" and"How to create a command-line predictor".
