I\'ve tried it just by typing

Answer 1

I had same problem when upgrading to Yosemite.

I just had to modify ~/.bashrc to source /usr/local/etc/bash_completion.d/git-prompt.sh instead of the old path.

then re-source your . ~/.bashrc to get the effect.

Answer 2

this works in OS 10.8 in the .bash_profile

if [ -f ~/.git-prompt.sh ]; then
  source ~/.git-prompt.sh
  export PS1='YOURNAME[\W]$(__git_ps1 "(%s)"): '
fi

Answer 3

For macports I had to add: source /opt/local/share/git-core/git-prompt.sh to my ./profile

Answer 4

At least with Xcode 6, you already have git-completion.bash. It's inside the Xcode app bundle.

Just add this to your .bashrc:

source `xcode-select -p`/usr/share/git-core/git-completion.bash

Answer 5

Please not that, if you haven't installed git through Xcode or home-brew, you'll likely find the bash scripts haysclarks refers to in /Library/Developer/CommandLineTools/, and not in /Applications/Xcode.app/Contents/Developer/, thus making the lines to include within .bashrc the following:

if [ -f /Library/Developer/CommandLineTools/usr/share/git-core/git-completion.bash ]; then
    . /Library/Developer/CommandLineTools/usr/share/git-core/git-completion.bash
fi

source /Library/Developer/CommandLineTools/usr/share/git-core/git-prompt.sh

You'll need those lines if you wish to use git-prompt as well. [1]: https://stackoverflow.com/a/20211241/4795986

Answer 6

You've installed the version of git-completion.bash from master - in git's development history this is after a commit that split out the __git_ps1 function from the completion functionality into a new file (git-prompt.sh). The commit that introduced this change, which explains the rationale, is af31a456.

I would still suggest that you just source the version of git-completion.bash (or git-prompt.sh) that is bundled with your installation of git.

However, if for some reason you still want to use this functionality by using scripts separately downloaded from master, you should download git-prompt.sh similarly:

curl -o ~/.git-prompt.sh \
    https://raw.githubusercontent.com/git/git/master/contrib/completion/git-prompt.sh

... and add the following line to your ~/.bash_profile:

source ~/.git-prompt.sh

Then your PS1 variable that includes __git_ps1 '%s' should work fine.
