so i know about the various discussions around a `du` that follows git-annex symlinks (e.g. [[forum/__34__du__34___equivalent_on_an_annex__63__/]] or [[forum/gadu_-_git-annex_disk_usage/]]. this is not about that. :)
i believe there's a distinct use-case for a simpler `du` subcommand that will calculate the disk space used locally (in case of the default `--in here`) but could also use the tracking log to determine the space usage in *other* locations. this would be especially useful on remotes that we don't have shell access to, s3 comes to mind. i thought that `git annex info` could output that, but it seems it doesn't:
<pre>
$ git annex info . --in s3 --exclude='video/original/*'

local annex size: 0 bytes

you can see the advantage of having a separate du command above: first off, it would give directly the information we're looking for. it could also work on remote repositories, use the powerful pattern matching, and so on...
thanks! [[anarcat]]
