Apple - git auto-complete for *branches* at the command line?

ok, so I needed the git autocompletion script.

I got that from this url:

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

No need to worry about what directory you're in when you run this as your home directory(~) is used with the target.

Then I added to my ~/.bash_profile file the following 'execute if it exists' code:

if [ -f ~/.git-completion.bash ]; then
  . ~/.git-completion.bash
fi

Update: I'm making these bits of code more concise to shrink down my .bashrc file, in this case I now use:

test -f ~/.git-completion.bash && . $_

Note: $_ means the last argument to the previous command. so . $_ means run it - "it" being .git-completion.bash in this case

This still works on both Ubuntu and OSX and on machines without the script .git-completion.bash script.

Now git Tab (actually it's git TabTab ) works like a charm!

p.s.: If this doesn't work off the bat, you may need to run chmod u+x ~/.git-completion.bash to grant yourself the necessary permission:

• chmod is the command that modifies file permissions
• u means the user that owns the file, by default its creator, i.e. you
• + means set/activate/add a permission
• x means execute permission, i.e. the ability to run the script

Some people prefer to use a package manager to automate the installing, updating, and configuring of Mac OS packages. I am a fan of package managers, and I think Homebrew is the best package manager for Mac OS (some would say it's the de-facto Mac OS package manager).

Once you have installed Homebrew, you can simply install git along with bash-completion with brew install git bash-completion.

You'll then need to put the following in your ~/.bash_profile:

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

(Note: If this install fails with a 404 error, and you already have git installed, just remove the git part of this brew install)

More info on installing git and bash-completion with brew here.

Run this on terminal:

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

Then, do this:

vi ~/.bash_profile

Add this lines:

if [ -f ~/.git-completion.bash ]; then
  . ~/.git-completion.bash
fi

That's all. This worked for me.
