attr.exe (week #24)

• The order in which you alter the attributes does not matter. For instance, you don't have to explicitly remove -r before -s, etc.
• You can combine attributes as in: `attr -rsh file`.
• You can modify multiple files via the same command-line as in: `attr -sa file1 file2 +hs file3`.

USAGE: attr.exe [options] [file] [file..n] [options file..n] ...

  no-arguments    Displays attributes for all files (and
                  directories) in the current directory.

  file            Specifies a file (or file wildcard) for attr 
                  to process.

OPTIONS:

    a     Archive file attribute.
    s     System file attribute.
    h     Hidden file attribute.

  /p --pause      Pause when finished.
  /r --recursive  Processes matching files in the current 
                  directory and all sub-directories. (also /s)
  /d              Processes directories as well.
                  (sorry this isn't implemented yet!)

     --showpath   Output each file's full path and name.
                  Default is file name only (without the path).
