Returning to the last cursor position in Vim

Add this to your ~/.vimrc:

augroup line_return " Return vim to the last known position
 au!
 au BufreadPost *
 \ if line("'\"") > 0 && line("'\"") <= line("$") |
 \ execute "normal! g'\"" |
 \ endif
augroup END

This snippet will return you to the last known cursor position when opening a file in vim. Very handy!
