VI Editor
The commands to move around the file are:
h Move the cursor left one character.
j Move the cursor down one line.
k Move the cursor up one line.
l Move the cursor right one character.
<cursor-arrows>
The cursor arrow keys should work, too.
/text<carriage-return>
Search for the string ``text'' in the file, and move the cursor to
its first character.
The commands to enter new text are:
a Append new text, after the cursor.
i Insert new text, before the cursor.
o Open a new line below the line the cursor is on, and start entering
text.
O Open a new line above the line the cursor is on, and start entering
text.
<escape>
Once you've entered input mode using the one of the a, i, O, or o
commands, use <escape> to quit entering text and return to command
mode.
The commands to copy text are:
yy Copy the line the cursor is on.
p Append the copied line after the line the cursor is on.
The commands to delete text are:
dd Delete the line the cursor is on.
x Delete the character the cursor is on.
The commands to write the file are:
:w<carriage-return>
Write the file back to the file with the name that you originally
used as an argument on the vi command line.
:w file_name<carriage-return>
Write the file back to the file with the name ``file_name''.
The commands to quit editing and exit the editor are:
:q<carriage-return>
Quit editing and leave vi (if you've modified the file, but not
saved your changes, vi will refuse to quit).
:q!<carriage-return>
Quit, discarding any modifications that you may have made.
One final caution. Unusual characters can take up more than one column
on the screen, and long lines can take up more than a single screen line.
The above commands work on ``physical'' characters and lines, i.e. they
affect the entire line no matter how many screen lines it takes up and
the entire character no matter how many screen columns it takes up.
