 To edit a file,  start at the prompt and issue the 
 vi command followed by the name of the file: 
 
> vi sample.doc  
  
vi.  Then you use the vi subcommand :n 
to edit the next file, or :e! to edit the previous file.  If 
you lose track of where you are, use :f to show your current 
file.)
The vi subcommands to move around are the same as in view. Try these:
[return]  | scrolls one line at a time | 
^f (ctrl+ f)  | scrolls forward a page | 
^b  | scrolls back a page | 
w  | move forward a word | 
b | move back a word | 
G  | Go to end of file | 
 0  | Go to beginning of file | 
Now that you know how to get started and get around in vi, let's actually make a couple of changes.
