A vi cheat sheet

Here is a small subset of vi commands (the ones most commonly used). The vi editor has

three modes:

1. Input mode: The Insert key, i, o (add a line below), O (add a line above) and other

commands put you in this mode. When you are in this mode, you will see the text

--INSERT-- in the last line.

2. Command mode: Pressing Esc takes you out of input mode and into command mode. The

relevant commands are:

i Brings you back to input mode.

dd Deletes a line and puts it into the buffer.

<n>dd Deletes <n> lines.

x Deletes a character.

dw Deletes a word.

p Adds the buffer past the current location.

P Adds the buffer before the current location.

o Adds a line and goes into insert mode.

/string Searches for a string.

n Performs the last command again.

jkl; Performs a cursor movement.

A Adds text at the end of the line.

<nn>G Goes to line <nn>.

G Goes to the last line in the file.

yy Yanks a line (copies into buffer).

<n>yy Yanks n lines.

3. Command line mode: Pressing the colon key puts you into this mode:

:wq Saves (writes and quits).

:q! Quits and discards changes.

:<nn> Goes to line number <nn>.

:r <file> Leads <file> into the current file.

:1,$s/old/new/g Globally replaces <old> with <new>.

:help Gives help.
