vi - Command mode i = input mode esc = command mode :se number = display line numbers :se nonumber = don't display line numbers :e = open file :w = save (write) file to disk :wq = save and quit :q! = quit but don't save number,command = apply command number times (e.g. 4,x = delete 4 characters) . = repeat last effective cmd esc,u = undo it vi - Command mode - Moving the cursor - = go to beginning of previous line 0 (zero) or ^ = go to beginning of this line $ = go to end of this line ret or + = go to beginning of next line (NOT THE SAME AS INPUT RETURN) w = go to beginning of next word b = go to beginning of this word e = go to end of this word sft-h = go to first line onscreen sft-l = go to last line onscreen ctrl-f = forward (down) one screen ctrl-b = backward (up) one screen 1,sft-g = top of the buffer sft-g = bottom of the buffer (i.e. EOF) line,sft-g = go to line (e.g. 3,5,sft-g = line 35) column,| = go to column (e.g. 4,| = column 4) vi - Command mode - Deletion deleted text is put to the general purpose buffer; use the p cmd to retrieve it you can also use yanks to not delete it but still put it in the GPB basically delete = cut and yank = copy in your OS's Edit menu x = delete this character d,w = delete word d,d = delete line sft-d = delete to end of line (same as emacs ctrl-k) y,w = yank to beginning of next word sft-y or y,$ = yank to end of line y,y = yank entire line buffer"lines"y,y = yank lines number of lines into buffer buffer (a-z) p = paste contents of general-purpose buffer vi - Command mode - Replacement to use replacers type the sequence and then type the string of characters to replace with, e.g. 2,c,w,"Bored Zo" to replace from the cursor to the end of the next word to "Bored Zo" r = replace a single character shift-r = replace characters from the cursor(e.g. if | is the cursor and your text is "I AM the |Entertained Zo!" shift-r,"Bored" will give you "I AM the Boredtained Zo!") c,w or c,e = change from cursor to end of word c,b = change from beginning of word to before cursor c,$ or sft-c = change from cursor to end of line c,c = change the ENTIRE line :x,ys/oldstring/newstring/ = substitute newstring for oldstring from line x to line y (if y = $ then to EOF) ~ = toggle a character's case vi - Command mode - Searching see section on regular expressions above / = search forward from cursor for a pattern ? = search backward from cursor for a pattern n = next result sft-n = previous result vi - Command mode - Insertion o = insert a blank line below this one sft-o = ...above this one :r file = insert file at cursor Back to the Index
