# Current branch - Determine current git branch, store in $currentbranch, and exit if not on a branch
if ! currentbranch=$(git symbolic-ref --short -q HEAD)
then
	echo We are not currently on a branch.
	exit 1
fi

# Uncommited Changes - Exit script if there uncommited changes
if ! git diff-index --quiet HEAD --; then
	echo "There are uncommited changes on this repository."
	exit 1
fi

# Remote exists - Exit script if remote does not exist
git ls-remote --exit-code ${remote} >/dev/null 2>&1
if [ $? -ne 0 ]
then
	echo "Remote ${remote} does not exist"
    exit 1
fi

# Root path of Repo
rootpath=$(git rev-parse --show-toplevel)

# Branch exists - Exit script if local branch does not exist
git rev-parse -q --verify ${branch} >/dev/null 2>&1
if [ $? -ne 0 ]
then
    echo "Branch ${branch} exists"
fi

Thank you, this is great!
