* Lesson 1.0 *
**************
vi is a very powerful editor that has many
commands, too many to
explain in a tutor such as this. This
tutor is designed to describe
enough of the commands that you will be able
to easily use vi as
an all-purpose editor.
The approximate time required to complete the
tutor is 25-30 minutes,
depending upon how much time is spent with
experimentation.
It is important to remember that this tutor is
set up to teach by
use. That means that you need to
execute the commands to
learn them properly.
Now, make sure that your Caps-Lock key is NOT
depressed and press
the j key or the down
arrow enough times to move the cursor
so that Lesson 1.1 completely fills the screen.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
**************
* Lesson 1.1 *
**************
=====>>>>> MOVING THE CURSOR <<<<<=====
Although the cursor can be moved with the arrow keys, it is important
to learn
to use the letters h, j, k, and l to move around as this can be used
later with
command line editing where the arrow keys cannot.
** To move the cursor, press the h,j,k,l keys as
indicated. **
^
k
< h l >
j
v
1. Move the cursor around the screen until you are comfortable.
2. Hold down the down key (j) until it repeats.
---> Now you know how to move to the next lesson.
3. Using the down key, move to Lesson 1.2.
Note: For the rest of this tutorial you
can use either the arrow
keys or the appropriate letters to move
around.
If you are ever unsure about something
you typed, press <ESC> to place
you in Command Mode. Then retype
the command you wanted.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

=====>>>>> ENTERING AND EXITING vi
<<<<<=====
!! NOTE: Before executing any of the steps below, read all
of lesson 1.2!!
1. Press the <ESC> key (to make sure you are in Command
Mode).
2. Type :q! <RETURN>.
---> This exits the editor WITHOUT saving any changes you have made.
If you want to save the changes and exit
type :wq <RETURN>
3. When you see the shell prompt ($) type: vi
tutor.vi <RETURN>.
---> 'vi' means enter the vi editor, 'tutor.vi' is the file you wish
to edit.
4. If you have these steps memorized and are confident, execute
steps
1 through 3 to exit and re-enter the
editor. Then cursor down to
Lesson 1.3.

* Lesson 2.4 *
**************
=====>>>>> AN
EXCEPTION TO 'COMMAND-OBJECT' <<<<<=====

decided
it would be easier to simply type two d's in a row to delete a
line.
1. Move the cursor to the second line in the phrase below.
2. Type dd to delete the line.
3. Now move to the fourth line.

name TEST.
To verify this, type
:!ls again to see your directory
---> Note that if you were to exit vi and enter again with the
filename TEST,
the file would be an exact copy of the tutor
when you saved it.
5. Now remove the file from your area by
typing: :!rm TEST
5. Again, see that the file is there with :!ls but
DO NOT remove it.

=====>>>>> RETRIEVING AND MERGING FILES
<<<<<=====
** To insert the contents of a
file, type :r FILENAME **
1. Type :!ls to make sure your TEST
filename is present from before.
2. Place the cursor at the top of this page.
NOTE: After executing Step 3 you will see Lesson 5.3. Then
move DOWN to
this lesson again.

TEST where TEST is
the name of the file.
NOTE: The file you retrieve is placed starting where the cursor
is located.
4. To verify that a file was retrieved, cursor back and notice
that there
are now two copies of Lesson 5.3, the original
and the file version.

********************
* LESSON 5 SUMMARY *
********************
1. :!command executes a unix system command.
Some useful examples are:
:!ls
- shows a directory listing of your area.
:!rm
FILENAME - removes file FILENAME from your area.
2. :w FILENAME writes the current vi file to disk
with name FILENAME.
3. :#,# w FILENAME saves the lines # through # in
file FILENAME.

This concludes the vi Tutor. It was intended to give a
brief overview of
the vi editor, just enough to allow you to use the editor fairly
easily.
It is far from complete as vi has many many more commands.
For more information on the vi editor please refer to the
on-line manuals:
'man vi' or 'man ex'
