Dear coreutils team,

I have coreutils 8.11 installed on my system via Arch Linux packages and have experienced some unexpected behaviour of the "du" utility. When I execute

du -hs . .git

in a folder that contains some files and a subfolder named ".git" the output I get is

194M    .

The output I would expect is

194M    .
97M     .git

If I change the order of the arguments to read

du -hs .git .

I get the output

97M     .git
97M     .

which again is not the desired result and in fact wrong because the reported size for '.' is 97M whereas a simple `du -hs .` reveals the size of '.' as 194M. It would be great if you could fix this bug or tell me what I did wrong here. :)

Keep up your great work!

Greetings from Germany, Edgar Kalkowski

I have got the latest Git master in /tmp and 8.5 from Fedora 14 installed
system-wide.

[rishi <at> freebook coreutils]$ /tmp/bin/du -hs .git .
32M		.git
9.5M		.
[rishi <at> freebook coreutils]$ /tmp/bin/du -hs . .git
41M		.
[rishi <at> freebook coreutils]$ /tmp/bin/du -hs .
41M		.
[rishi <at> freebook coreutils]$ /tmp/bin/du -hs .git
32M		.git
[rishi <at> freebook coreutils]$ du -hs .git .
32M		.git
41M		.
[rishi <at> freebook coreutils]$ du -hs . .git
41M		.
32M		.git
[rishi <at> freebook coreutils]$ du -hs .git
32M		.git
[rishi <at> freebook coreutils]$ du -hs .
41M		.
[rishi <at> freebook coreutils]$ 

I get similar results using 8.10 on Fedora 15.

If this is indeed a bug, then I can try to cook a patch.

Happy hacking,

No, it's expected.  In the NEWS file, it's the first bug
fix listed under coreutils 8.6.

Expected by who? I expect du -s prints exactly one line of output per
argument. The tool is too clever, outsmarting its users.

Yes, that is what I was thinking after going back and forth with Git.
However, I am confused because FreeBSD 8.1's du seems to have the earlier
behaviour.
