Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

[ Update 2020-05-31: I won't be maintaining this page or responding to comments anymore (except for perhaps a few exceptional occasions). ]

Helpfully handling Command Not Found in PowerShell

About CommandNotFoundAction

In PowerShell there is a callback ("Action") that is called when a command lookup fails through normal means. The purpose of this callback is to allow you to add your own command-resolution, and there are a lot of community hacks out there already:
