How to enable autocomplete resource for shell script?

Answer 1

The easiest way to do this is to include a shell script in /etc/bash_completion. d/. The basic structure of this file is a simple function that executes the completion and then the complete invocation which is a bash compiler. Instead of going into detail on how to use complete, I suggest you read an Introduction to Bash Completion. Part 1 covers the basics and Part 2 goes into how you would write a completion script.
