5.0 - What's online at the vi archives?

  There is a FAQ posted frequently which gives a list of all the files
that are online at the vi archive.  It also gives a list of addresses
which mirror the vi archive.  The main address is ftp://alf.uib.no/pub/, but it is
archived at many, many sites.  The vi-archive faq lists all of them.
Please check that faq before ftping to it, as there is almost definitely
a closer and therefore faster site to you than the one in Norway.
  A few mirrors are:  <ftp://ftp.uu.net/pub/text-processing/vi>.
                      <ftp://ftp.cc.monash.edu.au/pub/vi>
  The site has many, many files on vi, including a few clones.  It also
has the UCB distribution of vi, and lots of useful macros.  Check it
out.

6.0 - Silly vi tricks, and silly macros

  This section is for silly vi tricks, and silly macros.  Actually, any
interesting vi tricks and macros are acceptable, as long as they are
not too lengthy.  I will add any that are suggested to me that I think
are reasonable.

6.1 - Silly vi tricks
  Note: Also check out the Silly macros down below. Many macros and
tricks are interchangeable.

  xp     This will delete the character under the cursor, and put it
afterwards.  In other words, it swaps the location of two characters.
 
  ddp    Similar to xp, but swapping lines.
 
  yyp    duplicate a line

  uu     Undo and redo last change.  (This will take you to the last
modification to the file without changing anything.)  You can also use
this to compare the changes to a line.  Make the changes to the line,
press U to undo the changes to the current line, and then press u to
toggle between the two versions.

  :g/.*/m0
         This will reverse the order of the lines in the current file.
m0 is the ex command to move the line to line 0.

  :v/./d or :g/^$/d 
         Removes all blank lines.

  :g/^[ <ctrl-v><tab>]*$/d
         Removes all lines that only have whitespace.

  :v/./$s/$/<ctrl-v><enter>./|'';/./-1j|$d
         Replaces multiple blank lines with just one blank line.

6.2 - Silly macros
  Note:  <ctrl-x> means hold down control, and hit x.

  Swap character and one vertically above:
    map * kxjphxkP

  Fold a line that's too long
    map g $80<ctrl-v><ctrl-v>|F r<ctrl-v><enter>

  Change case on most words
    map v ywmno<ctrl-v><esc>P:s/./\~/g<ctrl-v><enter>0"nDdd`n@n

  Put `and' around the current word
    map *` i`<ctrl-v><esc>ea'<ctrl-v><esc>

  Put 'and' around the current word
    map *' i'<ctrl-v><esc>ea'<ctrl-v><esc>

  Put "and" around the current word
    map *" i"<ctrl-v><esc>ea"<ctrl-v><esc>

  Put `and' around the current word
    map! `` <ctrl-v><esc>bi`<ctrl-v><esc>ea'

  Split a line at the cursor, and put a > at the beginning of the next
line.  (For quoting Usenet, etc). I had some trouble with my old
version of this under some versions, so I've redone it, and I think
that it should work.
    map g may0O<ctrl-v><esc>P`ao<ctrl-v><esc>P:s/./ /g<ctrl-v><enter>0i><ctrl-v><esc>$mb`ay$`bP'add

  Insert one character
    map g i$<ctrl-v><esc>r

  Format a paragraph without the fmt program.  (To use, use J a few
times, then this a few times)
    map K 072lBhr<ctrl-v><enter>

  Or, a little less elegantly, but without the need to use J and K
multiple times.
    map K {wma}b:'a,.j<ctrl-v><enter>:s/\(.........................................................\)/\1<ctrl-v><ctrl-v><ctrl-v><enter>/g<ctrl-v><enter>

  Make ctrl-x work as cut, ctrl-v as paste, ctrl-p as copy.  You should
mark the beginning of the area as m (use mm).  (ctrl-c cannot be
remapped when it is defined as the interrupt character in Unix.)
    map <ctrl-v><ctrl-x> "zd`m
    map <ctrl-v><ctrl-p> "zy`m
    map <ctrl-v><ctrl-v><ctrl-v><ctrl-v> "zP`m

  Save a read-only file.  Careful, it changes the permissions. When
done, it changes them to read/write owner, read for everyone else. Note
that this might not be the same as the original permissions.
    map K :!chmod 666 %<ctrl-v><enter>:w!<ctrl-v><enter><ctrl-v><enter>
    :!chmod 644 %<ctrl-v><enter>

  vi status line (sort of...) [Note:  It's slow...]
    map <ctrl-v><up-arrow> k<ctrl-v><ctrl-g>
    map <ctrl-v><down-arrow> j<ctrl-v><ctrl-g>
    map k k<ctrl-v><ctrl-g>
    map j j<ctrl-v><ctrl-g>
    map <ctrl-v><ctrl-f> <ctrl-v><ctrl-f><ctrl-v><ctrl-g>
    map <ctrl-v><ctrl-b> <ctrl-v><ctrl-b><ctrl-v><ctrl-g>
    map H H<ctrl-v><ctrl-g>
    map M M<ctrl-v><ctrl-g>
    map L L<ctrl-v><ctrl-g>
    map G G<ctrl-v><ctrl-g>
    map <ctrl-v><ctrl-u> <ctrl-v><ctrl-u><ctrl-v><ctrl-g>
    map <ctrl-v><ctrl-d> <ctrl-v><ctrl-d><ctrl-v><ctrl-g>

  center a line
    map = 080i <ctrl-v><esc>$78hd0^D:s/  / /g<ctrl-v><enter>$p

  redefine tab to insert 5 spaces instead of a tab marker
    map! <ctrl-v><ctrl-i> <space><space><space><space><space>

  switch current and last line (repeat to reverse a file)
    map v Gdd''Pj

  yank until end of line, run it in a shell and read in the result
    map v y$o<ctrl-v><esc>pI:r!<ctrl-v><esc>"add@a

  allow vi to backspace over text that was inserted in a previous
insert mode
   map! <ctrl-v><ctrl-?> $<ctrl-v><esc>Xs
   map! <ctrl-v><ctrl-h> $<ctrl-v><esc>Xs

  print the document to the default printer (for BSD replace lp with lpr).
   map v 1G!Glp<ctrl-v><enter>u

  set # to toggle line numbers on and off:
   map \o# o:se nu<ctrl-v><enter>:se nonu<ctrl-v><esc>-:map \o# "wp<ctrl-v><enter>
   map \d# "w2dd
   map \x# "xdd@x"xpk
   map # ma3L\o#\x#\d#`a:<ctrl-v><enter>
 
  Quote the current paragraph with '>'s.
   map Z> mc{jma}kmb:'a,'bs/^ /> /<ctrl-v><enter>'c

  Allow <ctrl-z> to suspend processes within insert mode
   map! <ctrl-v><ctrl-z> <ctrl-v<esc>:stop<ctrl-v><enter>
  Make all tabs spaces
   map! <ctrl-v><ctrl-v><ctrl-v><ctrl-i> <ctrl-v><ctrl-v><space>

  Replace all tabs with the proper amount of spaces for the given
  tabstop. Removing the last two character (4<enter>) will allow you to
  specify the tabstop: #t4<enter>
   map #t 1G!Gpr -t -e4<ctrl-v><enter>
   map #T !}pr -t -e4<ctrl-v><enter>}

  Insert a ruler above the current line
   map #r O<ctrl-v><esc>i....+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8<ctrl-v><esc>

  This is a macro that redefines itself: (more for heuristic reasons
than anything else) It inserts foo the first time it is run, and bar
all subsequent times. 
  map K ifoo<ctrl-v><esc>:map K ibar<ctrl-v><ctrl-v><ctrl-v><esc><ctrl-v><enter>

  This makes end notes. It will insert a [#] at the current location
and put a [#] at the bottom of the document and let you type there.
Hitting `a will take you back to the original location once you are
done with your end note. [#] will be the number of the end note, not
the literal # character. (Pretty crazy, huh?)
   map K ma1GO[0]<ctrl-v><esc>G$?\[[0-9]*\]<ctrl-v><enter>lyt]`aa<ctrl-v><enter><ctrl-v><esc>O<ctrl-v><esc>pI:r!echo '1 <ctrl-v><esc>A + p' <ctrl-v><ctrl-v>| dc<ctrl-v><ctrl-v><ctrl-v><ctrl-v><ctrl-v><ctrl-v><ctrl-v><enter><ctrl-v><esc>0"yD@y0i[<ctrl-v><esc>A]<ctrl-v><esc>kkJJJmb1Gdd`bF[yf]Go<ctrl-v><esc>pA

8.0 - Setting up .exrc file

  Any commands that can be used in command input mode ( : commands),
may be used in a .exrc, which will load automatically whenever you
start vi.  In addition, the source command (so), abbreviations (ab),
and macros may be used.  There may not be any blank lines in your
.exrc.  A " in the first column may be used to tell vi that what
follows is a comment.

8.1 - Sample .exrc file

  This .exrc file is a real one.  Mine.  Because of that, it doesn't
set as many options as one might wish it did to get a good idea of what
may be used.  However, it should get the basic idea down, and it is
quite straightforward. 

First, note that you do not need to specify the :, it is assumed.

9.0 - Bugs in vi

  I'd like to say that vi is bug free, but unfortunately, it's not.
These bugs are bugs in the original vi, not necessarily in any of the
different clones.
  
  Macros for _ do not always work properly.
  #~ does not work under AIX

  The left and right hand side of macro definitions can be at most 100
characters. If they're more than 100 characters it doesn't give a
decent error message -- it either says that it is too dangerous to map
or that the rhs is missing.

10.0 - Glossary of terms

  This glossary will be updated as people suggest terms that they do
not understand.  Please let me know if you have any suggestions.

  command mode 
    Command mode is the mode within vi where the user gives commands to
vi.  (Including cursor movement commands, editing commands, etc.)

  ed 
    A non-visual editor under Unix.

 <Esc> 
    The escape key.  A key on a keyboard normally marked by escape.
Sometimes ^[ will work in its place.  If there is no escape key,
sometimes the Meta key will work.

  ex 
    An editor under Unix, all commands preceded with : are passed to
it.

  insert mode 
    Insert mode is the mode within vi where text is inserted into the
document.

  macro 
    A macro is a shortcut key combination.  For example, a macro allows
one to hit one letter and have it execute a few different commands.

  open mode 
    Open mode is the mode that vi will start in if it cannot determine
your terminal type, or if it believes you have a hardware or glass-tube
terminal.

  regular expressions (RegEx) (RE)
    Regular expressions, commonly known as "RegEx" or "REs" are a set
of key combinations that are meant to allow people to have a large
variety of control over what they are searching for.  RegEx is used a
lot under Unix, and is common between many programs.

  sed 
    Stream editor.  An editor that has no interface.  All commands
are given from the command line.

  vi 
    The editor to which this FAQ is dedicated.

Question how can you make the feature Join with correct syntax contained with a proper created vim.vim script file and called with cmdline and or from a bash script with /usr/bin/vi -e -s Filename < vim.vim script file. eg: called say Fix.vim script all other cmdline syntax work great as proper vi cmd syntax just Join or Shift-j will not work within a vim.vim script when called
looking for correct syntax use. Thank you.
