Making Commits

changing the index

$ git add filename  # adding new file; adding changes to the existing file
$ git add -p        # adding partial changes; git add --patch (-p)
$ git add -u        # include all files in the current index; this includes changed and deleted files, 
                    # but not new ones.
$ git add -A        # include all filenames in the index and in the working tree; this stages new 
                    # files as well
