LBS                       vi Command Reference                       CPS

Your terminal type (e.g., vt100) must be set correctly for vi to work.

When vi is in command mode, what you type is interpreted as commands to
vi. Some vi commands (a, i, c, et cetera) place vi in insert mode. In
insert mode, what you type goes in the buffer. Pressing ESC ends insert
mode and places vi in command mode. Most commands take a leading number
as a repetition factor, e.g., "5dd" deletes five lines.

:w          Save buffer changes in the file you are editing.
:wq         Exit and save buffer changes in the file you are editing.
:q!         Exit without saving changes (since the last :w) in the file.
:sh         Start a sub-shell. Ctrl-D to return to the editor.

:r file     Insert file into buffer following current line.
:r !cmd     Insert output of cmd into buffer follwing current line,
            e.g., ":r !date" inserts a line with the date and time.

:m,nw file  Write lines m through n to file (n and m are numbers).

Ctrl-G      Show filename, current line number, total lines in file.
nG          Go to line n. "G" alone goes to end of file.

h           Move cursor left one character.
j           Move cursor down one line.
k           Move cursor up one line.
l           Move cursor right one character (space bar does this also).

0           Move cursor to start of current line (zero).
$           Move cursor to end of current line.
b           Move cursor to start of previous word.
e           Move cursor to end of next word.
w           Move cursor to start of next word.

i           Enter insert mode before cursor.
a           Enter insert mode after cursor.
o           Enter insert mode on new line below current line (litle oh).
O           Enter insert mode on new line above current line (big oh).

x           Delete character under cursor.
dd          Delete line.
dw          Delete word.
D           Delete to end of line.

u           Undo last command. "U" restores line to original state.
.           Repeat last command that changes text.

fc          Search forward in line for character c.
Fc          Search backward in line for character c.

/str        Find str (search for a string within the file).
n           Repeat last "/" in the forward direction.
N           Repeat last "/" in the backward direction.
J           Join next line to current line.

yy          Yank (copy) line into special buffer.
nyy         Yank n lines into special buffer.
p           Copy yanked line(s) after cursor.
P           Copy yanked line(s) before cursor.
            Note: text deleted with the "x", "dd", "dw", or "D" commands
             may be retrieved with the "p" and "P" commands.

rc          Replace the character under the cursor with the character c.
s           Replace the character under the cursor with all the text typed
	     until an ESC is typed.
cw          Replace word with all the text typed until ESC.
C           Replace to end of lien with all the text typed until ESC.
R           Replace characters until an ESC is typed.

:n,ms/str1/str2/opt
            Search from n to m for str1. Replace str1 with str2. If opt
             is g, all occurences of str1 within range of the search are
             replaced. If opt is c, you are queried to confirm the change
             (y to change). If opt is p, changes are displayed.

&           Repeat last "s" command.

:g/str/cmd  Run cmd on all lines in the file that contain str. For
             example, ":g/wrongo/dd" deletes all lines that contain the
             string "wrongo".

:v/str/cmd  Run cmd on all lines that do not contain the string str.

:g/str1/s/str2/str3/opt
            For all lines containing str1, replace str2 with str3. Same
             options as "s" command. If str2 is null, the value of str1
             is used, e.g., :g/str1/s//str3/g replaces all instances of
             str1 with str3 in entire file.

            In search commands, the string searched for may contain
             general regular expressions (see UNIX manual entries for the
             ed and sed editors for full details). A few useful
             constructs are:

            ^str        str at beginning of line, so g/^/s//   / inserts
                        three spaces at start of every line in the file.
            str$        str at end of line.
            .           wildcard for any character.
            *           wildcard for any string.

:l          Display control characters in current line.
