But then propably all files below example_dir would have the same file
permission. What I would like to accomplish is to change only one bit of
the permissions. E.g. with something like

-rw-r--r-- file1
-rwxr--r-- file2
-r-xr-x--- file3
and I want to add group write permission I would get
-rw-rw-r-- file1
-rwxrw-r-- file2
-r-xrwx--- file3

But when I use something like chmod(0766) all files have the same file
permissions afterwarts. But maybe some of them shall stay executable and
some not.
