os.Path.rwx
Returns the UNIX™ file permissions of a file.
Syntax
os.Path.rwx(
   path STRING)
  RETURNS INTEGER
- path is the path to a file or directory.
 
Usage
This function returns the combination of permissions for user, group and other.
The mode is returned as a decimal value which is the combination
 of read, write and execution bits for the user, group and other part of the UNIX file permission. For example,
if a file has the -rwxr-xr-x permissions, the method
returns ((4+2+1) * 64 + (4+1) * 8) + (4+1) ) = 493.
In case of failure, the returned value is -1.
On Microsoft™ Windows®, this method always returns -1.
