There are several tools and libraries to help doing that, but since I am evaluating libraries in Go, I have decided to play with fsnotify and write a bit about it. https://fgiorgetti.github.io/posts/20210203-golang-bash-completion/ Wed, 03 Feb 2021 17:15:08 -0300 https://fgiorgetti.github.io/posts/20210203-golang-bash-completion/ In this post, I am going to share an example that demonstrates how to use bash completion with a Golang application that uses Cobra, a library to help writing Command Line Interface (CLI) apps. Source repository You can find the sources mentioned in this example at the following Git Repository. Pre-requisites You must have the following packages (assuming you’re on Linux) and commands available: go (1.15+) bash bash-completion base64 make The example application The code in the repository above demonstrates a very basic (and, let’s say, not so useful) application called bashcomp that handles the following commands:
