Documentation for method
mode assembled from the following types:
Return an IntStr object representing the POSIX permissions of a file. The Str part of the result is the octal representation of the file permission, like the form accepted by the chmod(1) utility.
say ~"path/to/file".IO.mode; # e.g. '0644'say +"path/to/file".IO.mode; # e.g. 420, where sprintf('%04o', 420) eq '0644'
The result of this can be used in the other methods that take a mode as an argument.
"path/to/file1".IO.chmod("path/to/file2".IO.mode); # will change the# permissions of file1# to be the same as file2
method mode(IO::Special: --> Nil)
The mode always returns Nil
