DESCRIPTION
vi (visual) is a display-oriented text editor based on an
underlying line editor ex. It is possible to use the com-
mand mode of ex from within vi and to use the command mode
of vi from within ex. The visual commands are described on
this manual page; how to set options (like automatically
numbering lines and automatically starting a new output line
when you type carriage return) and all ex line editor com-
mands are described on the ex(1) manual page.
When using vi, changes you make to the file are reflected in
what you see on your terminal screen. The position of the

vi(1) User Commands vi(1)
cursor on the screen indicates the position within the file.
The view invocation is the same as vi except that the
readonly flag is set.
The vedit invocation is intended for beginners. It is the
same as vi except that the report flag is set to 1, the
showmode and novice flags are set, and magic is turned off.
These defaults make it easier to learn how to use vi.
OPTIONS
Invocation Options
The following invocation options are interpreted by vi (pre-
viously documented options are discussed in the NOTES sec-
tion of this manual page):
- | -s Suppress all interactive user feedback. This
is useful when processing editor scripts.
-l Set up for editing LISP programs.
-L List the name of all files saved as the result
of an editor or system crash.
-R Readonly mode; the readonly flag is set,
preventing accidental overwriting of the file.
-r filename Edit filename after an editor or system crash.
(Recovers the version of filename that was in
the buffer when the crash occurred.)
-t tag Edit the file containing the tag and position
the editor at its definition.
-v Start up in display editing state using vi.
You can achieve the same effect by simply typ-
ing the -vi command itself.
-V Verbose. Any non-tty input will be echoed on
standard error. This may be useful when pro-
cessing editor commands within shell scripts.
-x Encryption option; when used, vi simulates the
X command of ex and prompts the user for a
key. This key is used to encrypt and decrypt
text using the algorithm of the crypt command.
The X command makes an educated guess to
determine whether text read in is encrypted or
not. The temporary buffer file is encrypted
also, using a transformed version of the key
typed in for the -x option.

vi(1) User Commands vi(1)
-wn Set the default window size to n. This is use-
ful when using the editor over a slow speed
line.
-C Encryption option; same as the -x option,
except that vi simulates the C command of ex.
The C command is like the X command of ex,
except that all text read in is assumed to
have been encrypted.
+command | -c command
Begin editing by executing the specified edi-
tor command (usually a search or positioning
command).
/usr/xpg4/bin/vi
If both the -t tag and the -c command options are given, the
-t tag will be processed first. That is, the file containing
the tag is selected by -t and then the command is executed.
OPERANDS
The following operands are supported:
filename A file to be edited.
COMMAND SUMMARY
vi Modes
Command Normal and initial mode. Other modes return
to command mode upon completion. ESC
(escape) is used to cancel a partial command.
Input Entered by setting any of the following
options: a A i I o O c C s S R. Arbitrary
text may then be entered. Input mode is nor-
mally terminated with ESC character, or,
abnormally, with an interrupt.
Last line Reading input for : / ? or !; terminate by
typing a carriage return; an interrupt can-
cels termination.
Sample commands
In the descriptions, CR stands for carriage return and ESC
stands for the escape key.
<- |v |^ -> arrow keys move the cursor
h j k l same as arrow keys
itextESC insert text
cwnewESC change word to new
easESC pluralize word (end of word; append s;
escape from input state)

Operators
Operators are followed by a cursor motion, and affect all
text that would have been moved over. For example, since w
moves over a word, dw deletes the word that would be moved
over. Double the operator, for example, dd to affect whole
lines.

AUTHOR
vi and ex were developed by The University of California,
Berkeley California, Computer Science Division, Department
of Electrical Engineering and Computer Science.
ENVIRONMENT
If any of the LC* variables ( LCCTYPE, LCMESSAGES,
LCTIME, LCCOLLATE, LCNUMERIC, and LCMONETARY ) (see
environ(5)) are not set in the environment, the operational
behavior of vi for each corresponding locale category is
determined by the value of the LANG environment variable.
If LCALL is set, its contents are used to override both the
LANG and the other LC* variables. If none of the above
variables is set in the environment, the "C" (U.S. style)
locale determines how vi behaves.
LCCTYPE
SunOS 5.5 Last change: 11 Apr 1995 7
vi(1) User Commands vi(1)
Determines how vi handles characters. When LCCTYPE is
set to a valid value, vi can display and handle text
and filenames containing valid characters for that
locale. vi can display and handle Extended Unix code
(EUC) characters where any individual character can be
1, 2, or 3 bytes wide. vi can also handle EUC charac-
ters of 1, 2, or more column widths. In the "C" locale,
only characters from ISO 8859-1 are valid.
LCTIME
Determines how vi handles date and time formats. In
the "C" locale, date and time handling follows the U.S.
rules.
FILES
/var/tmp default directory where temporary
work files are placed; it can be
changed using the directory option
(see the ex(1) set command)
/usr/share/lib/terminfo/?/*
compiled terminal description data-
base
/usr/lib/.COREterm/?/* subset of compiled terminal
description database

NOTES
Two options, although they continue to be supported, have
been replaced in the documentation by options that follow
the Command Syntax Standard (see intro(1)). A -r option
that is not followed with an option-argument has been
replaced by -L and +command has been replaced by -c command.
The message file too large to recover with -r option , which
is seen when a file is loaded, indicates that the file can
be edited and saved successfully, but if the editing session
is lost, recovery of the file with the -r option will not be
possible.
The editing environment defaults to certain configuration
options. When an editing session is initiated, vi attempts
to read the EXINIT environment variable. If it exists, the
editor uses the values defined in EXINIT, otherwise the
values set in $HOME/.exrc are used. If $HOME/.exrc does not
exist, the default values are used.
To use a copy of .exrc located in the current directory
other than $HOME, set the exrc option in EXINIT or
SunOS 5.5 Last change: 11 Apr 1995 8
vi(1) User Commands vi(1)
$HOME/.exrc. Options set in EXINIT can be turned off in a
local .exrc only if exrc is set in EXINIT or $HOME/.exrc.
Tampering with entries in /usr/share/lib/terminfo/?/* or
/usr/share/lib/terminfo/?/* (for example, changing or remov-
ing an entry) can affect programs such as vi that expect the
entry to be present and correct. In particular, removing
the "dumb" terminal may cause unexpected problems.
Software tabs using ^T work only immediately after the
autoindent.
Left and right shifts on intelligent terminals do not make
use of insert and delete character operations in the termi-
nal.
The standard Solaris version of vi will be replaced by the
POSIX.2 conformant version in the future. Scripts which use
the ex family of addressing and features should use the
/usr/xpg4/bin version of these utilities.
