How do you make Vim take you back where you were when you last edited a file?

My work computer has this feature, but not my home computer! How do you set Vim to remember in which part of a file you were when you last edited it?

EDIT: just to be more precise, I want this behavior when opening a new file, or on startup.

Answer 1

I have this in my .vimrc and it works:

" go to the position I was when last editing the file
au BufReadPost * if line("'\"") > 0 && line("'\"") <= line("$") | exe "normal g'\"" | endif

Answer 2

This is done with the viminfo file. It should be sufficient simply to enable this feature (and ensure that the file is writable). I use:

set viminfo='25,\"50,n~/.viminfo

...which stores viminfo data into ~/.viminfo. You can read about the other customization options here.

Answer 3

First, check that your .vimrc file is writable.

If that isn't sufficient, add this to your .vimrc:

if has("autocmd")
    autocmd BufReadPost *
    \ if line("\'") > 0 && line("\'") <= line("$") |
        \ exe "normal g`" |
    \ endif
endif
