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!
