(os/perm-string int)
Convert a Unix octal permission value from a permission integer as
returned by os/stat to a human readable string, that follows the
formatting of unix tools like ls. Returns the string as a 9
character string of r, w, x and - characters. Does not include the
file/directory/symlink character as rendered by `ls`.
