How to enable bash completion in macOS

macOS does not have Bash autocomplete feature installed and enabled by default as Linux distributions like Ubuntu. You will have to install and configure the bash-completion program for macOS to enable it, which is available via Homebrew.

bash-completion can be installed and enabled in macOS from the terminal.

Steps to enable bash completion in macOS:

Launch Terminal.

Install Homebrew by running the following commands.

$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Install bash-completion via Homebrew.
```
$ brew install bash-completion
```
Manually enable bash-completion for current session.
```
$ . /usr/local/etc/bash_completion
```
Automatically enable bash-completion when launching a new shell session by adding the following lines to ~/.bashrc or ~/.bash_profile.
```
[ -f /usr/local/etc/bash_completion ] && . /usr/local/etc/bash_completion
```
