Auto indent / format code for Vim?

To indent the whole file automatically:

gg
=G

Explained:

I don't know about auto-formatting existing code, but if you are writing code and need auto indent:

:set autoindent (or :set ai) will turn on auto-indent
Ctrl-d to un-indent (AKA outdent) your code
Tab or spaces to indent -- I personally use tab
:set tabwidth=4 (or :set tw=4) will control how many spaces a tab should indent code
The >> command will indent the current line. If you prefix it by a number, say 4>> then it will indent 4 lines, starting with the current line.
Likewise the << command will un-indent a line

I hope this gives you a good start.

Auto Indent *.sh

Just add the following lines in ~/.vimrc

filetype indent on
set smartindent
autocmd BufRead,BufWritePre *.sh normal gg=G
