vi - A Full Screen Text Editor
(Page 2 of 4)

Modes and Commands

vi has two basic modes: the command mode and the insert mode. vi normally starts in command mode and command mode can always be reached by pressing the escape key (hereafter shown as <esc> ). Most experienced vi users will be seen frequently pressing the escape key (their security blanket to be certain they are in command mode).

Table 16 summarizes the basic command structures, screen navigation commands, and editing commands available in vi.

**Table 16: Common vi Editor Commands**
Command	Function
ZZ, :wq	Save and Exit.
:q!	Exit without Save
DownArrow	Forward one line (or N lines).
UpArrow	Backward one line (or N lines).
RightArrow	Move right one character
LeftArrow	Move left one character
i	Start insert under the cursor
a	Start insert immediately after the cursor
o	Insert empty line below cursor and start insert at beginning of line
O	Insert empty line above cursor and start insert at beginning of line
/pattern	Search forward for next word matching pattern.
?pattern	Search backward for next word matching pattern.
n	Repeat previous search
N	Repeat previous search in reverse direction.
x	Delete character under cursor
dd	Delete current line
dw	Delete current word
db	Delete previous word
d/pattern	Delete from cursor to next word matching pattern

Command Structure

Basic command structure:

[rep-count] command [span of control]

Breaking this down: rep-count gives the number of times the command is to be repeated and the span of control modifies the amount of the editor buffer that the command will affect. For example with the delete command, the span of control can cause the next word, the next line, or the rest of the file to be deleted.
