Sometimes fdupes report files pointing to same inode as duplicate even when -H parameter isn't used.

Hello, I'm forwarding the Debian bug as reported at: http://bugs.debian.org/670631 >>> Try runnig these commands:

mkdir 1 2 3 echo AAAAAAAAAAAAAAA > 1/A1 echo AAAAAAAAAAAAAAA > 2/A2 ln 1/A1 3/A3 echo BBBBBBBBBBBBBBB > 1/B1 echo BBBBBBBBBBBBBBB > 2/B2 ln 2/B2 3/B3 echo CCCCCCCCCCCCCCC > 1/C1 ln 1/C1 2/C2 echo CCCCCCCCCCCCCCC > 3/C3 ls -li [123]/[ABC][123] fdupes -r 1 2 3 fdupes -r 1 3 2 fdupes -r 2 1 3 fdupes -r 2 3 1 fdupes -r 3 1 2 fdupes -r 3 2 1

When you run the fdupes commands, it should report two duplicate Ax files, two duplicate Bx files and two duplicate Cx files. Not three files, as the third file is a link. But sometimes this isn't the case:

fdupes -r 1 3 2

3/A3 2/A2

1/B1 2/B2

1/C1 3/C3 2/C2

ls -li [123]/[ABC][123]

90180 -rw-r--r-- 2 root root 16 Apr 27 14:53 1/A1 90182 -rw-r--r-- 1 root root 16 Apr 27 14:53 1/B1 90185 -rw-r--r-- 2 root root 16 Apr 27 14:53 1/C1 90181 -rw-r--r-- 1 root root 16 Apr 27 14:53 2/A2 90184 -rw-r--r-- 2 root root 16 Apr 27 14:53 2/B2 90185 -rw-r--r-- 2 root root 16 Apr 27 14:53 2/C2 90180 -rw-r--r-- 2 root root 16 Apr 27 14:53 3/A3 90184 -rw-r--r-- 2 root root 16 Apr 27 14:53 3/B3 90186 -rw-r--r-- 1 root root 16 Apr 27 14:53 3/C3

As seen above, fdupes report "1/C1" and "2/C2" ad duplicates, even though they point to the same inode. <<<
