Mac OS X - Install Git Completion

install-git-completion.sh

GIT_VERSION=`git --version | awk '{print $3}'`
URL="https://raw.github.com/git/git/v$GIT_VERSION/contrib/completion/git-completion.bash"


BASHRC="$HOME/.bashrc"

echo "Downloading git-completion for git version: $GIT_VERSION..."
if ! curl "$URL" --silent --output "$HOME/.git-completion.bash"; then
	echo "ERROR: Couldn't download completion script. Make sure you have a working internet connection." && exit 1
fi

SOURCE_LINE="source ~/.git-completion.bash"


if [[ -f "$BASHRC" ]] && grep -q "$SOURCE_LINE" "$BASHRC"; then
	echo "Already added to bashrc."
else
	echo "Adding to bashrc..."
	echo "$SOURCE_LINE" >> "$BASHRC"
fi

echo "Reloading bashrc..."
source "$BASHRC"

echo
echo "Successfully installed."
echo "Git auto-completion should be all set!"

i think its better to add "source ~/.git-completion.bash" to $HOME/.bashrc than $HOME/.profile
