DESCRIPTION

       Vi  is  a screen oriented text editor.  Ex is a line-oriented text edi-
       tor.  Ex and vi are different interfaces to the same program, and it is
       possible  to switch back and forth during an edit session.  View is the
       equivalent of using the -R (read-only) option of vi.

       This manual page is the one provided with the nex/nvi versions  of  the
       ex/vi  text  editors.   Nex/nvi	are intended as bug-for-bug compatible
       replacements for the original  Fourth  Berkeley	Software  Distribution
       (4BSD)  ex  and vi programs.  For the rest of this manual page, nex/nvi
       is used only when it's necessary to distinguish it  from  the  historic
       implementations of ex/vi.

       This  manual  page  is  intended for users already familiar with ex/vi.
       Anyone else should almost certainly read a good tutorial on the	editor
       before  this  manual page.  If you're in an unfamiliar environment, and
       you absolutely have to get work	done  immediately,  read  the  section
       after  the options description, entitled ``Fast Startup''.  It's proba-
       bly enough to get you going.

       The following options are available:

       -c     Execute cmd immediately after starting the edit  session.   Par-
	      ticularly  useful  for  initial positioning in the file, however
	      cmd is not limited to positioning commands.  This is  the  POSIX
	      1003.2 interface for the historic ``+cmd'' syntax.  Nex/nvi sup-
	      ports both the old and new syntax.

       -e     Start editing in ex mode, as if the command name were ex.

       -F     Don't copy the entire file when first starting  to  edit.   (The
	      default is to make a copy in case someone else modifies the file
	      during your edit session.)

       -l     Start editing with the lisp and showmatch options set.

       -G     Start editing in gtags mode, as if the gtagsmode option was set.

       -R     Start  editing  in  read-only  mode,  as if the command name was
	      view, or the readonly option was set.

       -s     Enter batch mode; applicable only to ex  edit  sessions.	 Batch
	      mode  is	useful	when running ex scripts.  Prompts, informative
	      messages and other user oriented message are turned off, and  no
	      startup  files  or  environment variables are read.  This is the
	      POSIX 1003.2 interface for the historic ``-'' argument.  Nex/nvi
	      supports both the old and new syntax.

       -t     Start editing at the specified tag.  (See ctags(1)).

       -w     Set the initial window size to the specified number of lines.

       -v     Start editing in vi mode, as if the command name was vi or view.

       Command input for ex/vi is read from the standard  input.   In  the  vi
       interface,  it is an error if standard input is not a terminal.	In the
       ex interface, if standard input is not a terminal, ex  will  read  com-
       mands  from  it	regardless,  however, the session will be a batch mode
       session, exactly as if the -s option had been specified.

       Ex/vi exits 0 on success, and greater than 0 if an error occurs.

FAST STARTUP

       This section will tell you the minimum amount that you need to do  sim-
       ple  editing  tasks  using  vi.	If you've never used any screen editor
       before, you're likely to have problems even with this simple  introduc-
       tion.   In  that case you should find someone that already knows vi and
       have them walk you through this section.

       Vi is a screen editor.  This means that it takes up almost  the	entire
       screen, displaying part of the file on each screen line, except for the
       last line of the screen.  The last line of the screen is used  for  you
       to give commands to vi, and for vi to give information to you.

       The other fact that you need to understand is that vi is a modeful edi-
       tor, i.e. you are either entering text or you are  executing  commands,
       and  you have to be in the right mode to do one or the other.  You will
       be in command mode when you first start editing a file.	There are com-
       mands  that  switch  you  into  input mode.  There is only one key that
       takes you out of input mode, and that is the <escape> key.  (Key  names
       are  written  using  less-than  and  greater-than signs, e.g.  <escape>
       means the ``escape'' key, usually labeled ``esc''  on  your  terminal's
       keyboard.)   If	you're	ever confused as to which mode you're in, keep
       entering the <escape> key until vi beeps at you.  (Generally,  vi  will
       beep  at  you  if you try and do something that's not allowed.  It will
       also display error messages.)

       To start editing a file, enter  the  command  ``vi  file_name<carriage-
       return>''.   The  command you should enter as soon as you start editing
       is ``:set verbose showmode<carriage-return>''.  This will make the edi-
       tor give you verbose error messages and display the current mode at the
       bottom of the screen.

       The commands to move around the file are:

       h      Move the cursor left one character.

       j      Move the cursor down one line.
       /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  com-
	      mand 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 origi-
	      nally 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.

SET OPTIONS

       There are a large number of options that  may  be  set  (or  unset)  to
       change  the  editor's  behavior.   This	section describes the options,
       their abbreviations and their default values.

       In each entry below, the first part of the tag line is the full name of

ENVIRONMENT VARIABLES

       COLUMNS
	      The number of columns on the screen.  This value	overrides  any
	      system  or terminal specific values.  If the COLUMNS environment
	      variable is not set when ex/vi runs, or the  columns  option  is
	      explicitly  reset  by  the user, ex/vi enters the value into the
	      environment.

       EXINIT A list of ex startup commands, read if the variable  NEXINIT  is
	      not set.

       HOME   The  user's  home  directory, used as the initial directory path
	      for the  startup	``$HOME/.nexrc''  and  ``$HOME/.exrc''	files.
	      This  value  is also used as the default directory for the vi cd
	      command.

       LINES  The number of rows on the screen.  This value overrides any sys-
	      tem or terminal specific values.	If the LINES environment vari-
	      able is not set when ex/vi runs, or the lines option is  explic-
	      itly reset by the user, ex/vi enters the value into the environ-
	      ment.

       NEXINIT
	      A list of ex startup commands.

       SHELL  The user's shell of choice (see also the shell option).

ASYNCHRONOUS EVENTS

       SIGALRM
	      Vi/ex uses this signal for periodic backups  of  file  modifica-
	      tions  and  to  display  ``busy''  messages  when operations are
	      likely to take a long time.

       SIGHUP

       SIGTERM
	      If the current buffer has changed since it was last  written  in
	      its  entirety,  the editor attempts to save the modified file so
	      it can be later recovered.  See the vi/ex Reference manual  sec-
	      tion entitled ``Recovery'' for more information.

       SIGINT When  an	interrupt occurs, the current operation is halted, and
	      the editor returns to the command level.	If interrupted	during
	      text  input, the text already input is resolved into the file as
	      if the text input had been normally terminated.

       SIGWINCH
	      The screen is resized.  See the vi/ex Reference  manual  section
	      entitled ``Sizing the Screen'' for more information.

       SIGCONT

       SIGQUIT

       SIGTSTP
	      Vi/ex ignores these signals.

FILES

       /bin/sh
	      The default user shell.

       /etc/vi.exrc
	      System-wide vi startup file.

       /tmp   Temporary file directory.

       /var/tmp/vi.recover
	      The default recovery file directory.

       $HOME/.nexrc
	      1st choice for user's home directory startup file.

       $HOME/.exrc
	      2nd choice for user's home directory startup file.

       .nexrc 1st choice for local directory startup file.

       .exrc  2nd choice for local directory startup file.

HISTORY

       The nex/nvi replacements for the ex/vi editor first appeared in 4.4BSD.

STANDARDS

       Nex/nvi	is close to IEEE Std1003.2 (``POSIX'').  That document differs
       from historical ex/vi practice in several places; there are changes  to
       be made on both sides.
