I'm not sure how useful this would be for you but here is another great thing you can do with Git. See readme.md @ https://github.com/hagzag/files_repo/blob/master/README.md BTW why rsync data to a git aware dir ? - just wanted to keep my files dir clean from the .git and it wasn't a matter of disk space, you could use the FILE_DIR and init git …

gistfile1.sh

#!/bin/bash

ACTION=${1:-execute}
FILES_DIR=${2:-/opt/data}
MY_GIT_REPO=${3:-/opt/git-repo}
GIT_REMOTE=${4:-git@github.com:${USER}/files_repo.git}

syncfilesdir() {
  src_dir=${1}
  dst_dir=${2}
  
  pushd ${src_dir} &>/dev/null
    rsync -avzp --delete --exclude .git --exclude .gitignore . ${dst_dir}
  popd &>/dev/null
}

gitavail(){
  git_dir=${1}
  pushd  ${git_dir} &>/dev/null 
    test -d .git || git init .
  popd &>/dev/null
}

remoteavail(){
  [ "$#" -lt 2 ] && fail "did not pass git local and remote"
  git_dir=${1} 
  git_remote=${2}

  pushd  ${git_dir} &>/dev/null
    remotes=`git remote`
    [ "${remotes}" = "" ] && git remote add origin ${git_remote}
  popd &>/dev/null
}

gitcommit() {
  git_dir=${1} 
  pushd  ${git_dir} &>/dev/null
    commitmsg=`git status -s`
    if [[ "${commitmsg}" =~ "(working directory clean)" ]]; then
      echo "nothing to commit"; exit 0
    else
      commitmsg=`git status -s | tr "?" " "`
      git add -A
      git commit -a -m "$commitmsg";
    fi
  popd &>/dev/null
}

gitpush() {
  pushd  ${1} &>/dev/null
    git push origin master
  popd &>/dev/null
}

fail(){
  message=${1:-`echo "An unknown error has occored whilst executing $0"`}
  echo "$message - $0 will now exit"
  exit 2
}

usage(){
  printf "$0 {sync|execute} [ACTION FILES_DIR MY_GIT_REPO GIT_REMOTE]
          defaults to:
            $0 execute /opt/data/ /opt/git-repo git@github.com:${USER}/files_repo.git
