Task

Rename:

   a file called     input.txt     into     output.txt     and 
   a directory called     docs     into     mydocs.


This should be done twice:  
once "here", i.e. in the current working directory and once in the filesystem root.

It can be assumed that the user has the rights to do so.

(In unix-type systems, only the user root would have
sufficient permissions in the filesystem root.)




RENAME "input.txt" TO "output.txt"
RENAME "/input.txt" TO "/output.txt"
RENAME "docs" TO "mydocs"
RENAME "/docs" TO "/mydocs"
