How To Set Up Git Tab Completion

First, open a shell and navigate to your home directory because that’s where the script will reside.

cd

Now download the git completion script using one of the following methods.

Using curl:

curl -O https://raw.githubusercontent.com/git/git/master/contrib/completion/git-completion.bash

Using wget:

wget https://raw.githubusercontent.com/git/git/master/contrib/completion/git-completion.bash

source ~/git-completion.bash

In most cases, you’ll want to source this file automatically whenever you start a new shell. To do so, open your ~/.bashrc file and append the command from above. Once you save the file, all new shells will automatically source the file.

Note: The tilde (~) refers to your home directory.

Move to a git controlled directory and type:

git checkout 

You should see a list of all of the possible branches that can be checked out!
