Re: feature request du/find

[Benjamin Arnold]

Hi,

thanks a lot for your quick response.

Sorry, i must have missed the -links option, that's exactly what i am
looking for.

In my case du would have counted "twice", because the other hard link is
not in the directory du is searching in.

Thanks again and thank you all for your commitment!
