[ELECTRON] Shell Scripting help? "test: [-d: unary operator expected"

[Simon Yuill]

Hi Ben,

This bit of Python will do the dame job for you, if you can use Python
for your scripts:


def validateFilePath(filepath, create=False, isDirectory=False):
	"""
	Converts C{filepath} to absolute form, expanding the
	user if necessary,and tests if it exists.  If the
	directory, or any sub-directory in the path
	does not exist, can optionally create it (off by default).

	Returns validated path.  If C{create} is set to false,
	and the path does not exist, returns C{None}.
	"""
	absfilepath = os.path.abspath(os.path.expanduser(filepath))
	if filepath[-1] == '/':absfilepath = absfilepath + '/'
	if not isDirectory:dirpath = os.path.dirname(absfilepath)
	else:dirpath = absfilepath
	if os.path.exists(dirpath):return absfilepath
	if create:
		os.makedirs(dirpath)
		return absfilepath
	else:return None


best wishes
Si
