Subject: [coreutils] Bug in du with -x flag?
Content-Type: text/plain; charset=ISO-8859-1
Content-Transfer-Encoding: 7bit


    Hi list,

  I always used to use du with the -cxhs options, but since updating to the
latest (8.15-1) version there appears to be a problem caused by -x:

> $ ls -la
> total 392188
> drwxr-xr-x+ 1 DKAdmin None         0 Apr  6 00:35 .
> drwxr-xr-x+ 1 DKAdmin None         0 Apr  3 05:58 ..
> drwxr-xr-x+ 1 DKAdmin None         0 Apr  3 16:28 gcc4
> -rw-r--r--  1 DKAdmin None 401599997 Apr  6 00:43 gcc472-2-dist.tar.bz2
> 
> $ du -xh gcc472-2-dist.tar.bz2
> 
> $ du -h gcc472-2-dist.tar.bz2
> 383M    gcc472-2-dist.tar.bz2
> 
> $

  Unless I'm misunderstanding it badly, -x shouldn't make any difference when
counting a real file in the current directory.  I wonder if it could have
perhaps been introduced by the recent related bugfix that I read about in
/usr/share/doc/coreutils/NEWS:

>   du -x no longer counts root directories of other file systems.
>   [bug introduced in coreutils-5.1.0]

or perhaps some interaction between that and Cygwin's path conversion code?

    cheers,
      DaveK
