Treat git directories, recursively. Is especially like the fact that I can use it together with git aliases, e.g. I use this at least once a (working) day like `gr -b /path/to/customer/git/repos fap` (--fetch --all --prune).

  usage(){
    printf "[TRACE=...] %s [-b /path/to/clones/root] (%s/w) -- <git commands/options>\n" "${0##*/}" "$HOME"
  }

  if [[ -n "${TRACE-}" ]]; then
    set -o xtrace
  fi

  trap 'set +o xtrace' ALRM HUP INT TERM EXIT

  : "${GIT_BASE:=$HOME}"
  while getopts b:h OPT; do
    case "$OPT" in
      b) GIT_BASE="$OPTARG";;
      h) usage; exit 0;;
      *) ;;
    esac
  done
  shift $(( OPTIND - 1 ))

  while read -r REPO; do
    [[ -d "$REPO"/.git ]] || continue
    [[ "$REPO" =~ \.terraform\/modules ]] && continue

    tput setaf 8

    if [[ $# -eq 0 ]]; then
      git -C "$REPO" status -sb
    else
      git -C "$REPO" "$@"
    fi
    printf "\n"
  done < <( fd --one-file-system --type d . "$GIT_BASE" )
