% File on disk
- Current buffer

Diff current unsaved buffer with saved version
:w !diff % -

Settings commands by default

If a particular option or command needs to be the default in Vim - it needs to be run every time you start Vim - create a text file called .exrc or .vimrc in your home directory and place your commands in there without the proceeding colon. For example to display line numbers and search case insensitively by default your .vimrc file would look like this:

set number
set ignorecase

Viewing panes

To split the current file into two horizontal panes:
:split
Use Ctrl+W to switch panes.

Recall previous command

Press Esc to enter command mode, type a single colon, after which the up and down keys can be used in the same manner as BASH.

Redo last typed text

Type a set of text in INSERT mode and go into COMMAND mode by pressing Esc. Now pressing . (a dot/period) will re-type the text typed in.

Tabs

Vim can open many files at once and arrange them in tabs:

vim -p blah.csv blah2.csv

To move between tabs use :tabn and :tabp

Run a command on all files/tabs open

 :tabdo $s/replace/this/g
