MacOS – Git auto-completion not working on Mac OSX 10.11.5 El Capitan

bashgithomebrewmacosterminal

I have tried the examples found here to get Git auto-completion working on El Capitan, however none of the examples work for me.

I installed bash-completion with Homebrew (brew install bash-completion).

This is my ~/.bash_profile currently (as you can see, i've tried a few things):

CRMPiccosMacBook:etc crmpicco$ cat ~/.bash_profile 
alias ll='ls -lG'
alias composer="php /usr/local/bin/composer.phar"

#if [ -f $(brew --prefix)/etc/bash_completion ]; then
#   . $(brew --prefix)/etc/bash_completion
#fi

if [ -f `brew --prefix`/etc/bash_completion.d/git-completion.bash ]; then
    . `brew --prefix`/etc/bash_completion.d/git-completion.bash
fi

#source /usr/local/git/contrib/completion/git-completion.bash
#GIT_PS1_SHOWDIRTYSTATE=true
#export PS1='[\u@mbp \w$(__git_ps1)]\$ '

So, if I go into my directory with the cloned Git repo and type git checkout m and hit [TAB] I get nothing (when expecting master to be pre-filled).

When I run a source on it, it doesn't exist – however it's installed. 

CRMPiccos-MacBook:signup crmpicco$ brew install bash-completion
Warning: bash-completion-1.3_1 already installed
CRMPiccos-MacBook:signup crmpicco$ source /etc/bash_completion.d/git-completion.bash
-bash: /etc/bash_completion.d/git-completion.bash: No such file or directory

You are confusing the basic bash completion with the add on required for completing git commands.

The git that is installed by Apple lacks the required git-completion.bash file so you need to install the full git. You can do this easily with homebrew -brew install git will do the job.

Once you've done that then uncomment your top three lines :-

if [ -f $(brew --prefix)/etc/bash_completion ]; then
    . $(brew --prefix)/etc/bash_completion
fi

Now source ~/.bash_profile and it should work fine.
