SAVING WORK AND EXITING 
------------------- 

    :q                      | Quit vi, unless the buffer has been changed.
    :q!                     | Quit vi without writing.
    ^Z                      | Suspend vi.
    :w                      | Write the file.

    :w >>             | Append the buffer to the file .
    :w!               | Overwrite the file .
    :x,y w            | Write lines x through y to the file .
    :wq                     | Write the file and quit vi; some versions quit

                            |   quit vi.  If you have invoked vi with the `-r'
                            |   option, you'd better write the file
                            |   explicitly (`w' or `w!'), or quit the
                            |   editor explicitly (`q!') if you don't want
                            |   to overwrite the file - some versions of vi
    :e                | Edit another file without quitting vi - the
                              text can be copied from one file to
                            |   another this way.
