Re: [coreutils] Bug in du with -x flag?
Greetings, Dave Korn! 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 40157 Apr 6 00:43 gcc472-2-dist.tar.bz2 $ du -xh gcc472-2-dist.tar.bz2 $ du -h gcc472-2-dist.tar.bz2 383Mgcc472-2-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 in du
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Reini Urban reported a du bug on the cygwin list - using mount points (or directory hard links on systems that support that) confuses the default behavior, and files are being double-counted and inflating the actual disk space in usage. In the example below, I used cygwin's mount feature to mount dir3 atop dir1. $ ls -iRF .: 14952513712823677584 dir1/ 2251799813894795 file1 28147497671275154 dir2/ 2251799813894795 file2 14952513712823677584 dir3/ ./dir1: 17343925114957410972 file ./dir2: 17343925114957410972 file ./dir3: 17343925114957410972 file $ du 1 ./dir1 # dir1/file counted... 0 ./dir2 # ...skipped since st_nlink is 2 0 ./dir3 # ...skipped since st_nlink is 2 2 . # and ./file[12] counted once $ du -l # ...where file was also linked outside linked directories 1 ./dir1 # dir1/file counted once... 1 ./dir2 # twice 1 ./dir3 # third time 5 . # plus 2 more for ./file[12] $ echo testing dir3/file3 $ ls -iRF .: 14952513712823677584 dir1/ 2251799813894795 file1 28147497671275154 dir2/ 2251799813894795 file2 14952513712823677584 dir3/ ./dir1: 17343925114957410972 file 1970324837184162 file3 ./dir2: 17343925114957410972 file ./dir3: 17343925114957410972 file 1970324837184162 file3 $ du 2 ./dir1 # dir1/file and dir1/file3 counted 0 ./dir2 # dir2/file skipped 1 ./dir3 # dir3/file skipped, but dir3/file3 counted! 4 . # and ./file[12] counted once.

Eric Blake [EMAIL PROTECTED] writes: One possible fix is revisiting line 377 in src/du.c in CVS, which currently skips hard links only if a file has multiple links. Sorry, I don't quite follow this. Don't all the directories in question have multiple links? Or, if you're talking about walking through the directory multiple times and discarding each file you find, that sounds pretty slow. The other fix would be to also check directories for identical inodes, and not descending through a directory by a second spelling if it has already been visited once. That makes more sense to me, anyway: directories should be treated like other files. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
