Simple alternative for **cp** but shows progress

cpv.sh

cpv() {
if ! type -P pv >/dev/null;then
  echo need pv >&2
  return 1
fi
case $# in
  0|1)
	echo invalid arguments >&2
	return 1
	;;
  2)
	if [[ -f "$1" ]];then
	  if [[ ! -e "$2" ]] || [[ -f "$2" ]];then
		pv "$1" > "$2"
	  elif [[ -d "$2" ]];then
		pv "$1" > "$2/$(basename "$1")"
	  fi
	elif [[ -d "$1" ]];then
	  if [[ ! -e "$2" ]];then
		(cd "$1" || exit 1
		mkdir "$2" || exit 1
		tar cf - . | pv | tar xf - -C "$2")
	  elif [[ -d "$2" ]];then
		tar cf - "$1" | pv | tar xf - -C "$2"
	  fi
	fi
	;;
  *)
	local args dest
	args=("$@")
	dest=${args[${#args[@]}-1]}
	unset args[${#args[@]}-1]
	if [[ -d "$dest" ]];then
	  tar cf - "${args[@]}" | pv | tar xf - -C "$dest"
	fi
	;;
esac
}

cpv "$@"
