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

     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

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

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

     $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.
