[Message part 1 (text/plain, inline)]

*OS:* Fedora; Tested in Bash v.5.1.

Hello. Task: Printing total size of files *alone*.
To reproduce:

$ stat -c '%i %h %s %n %F' k l
4198568 2 34 k regular file
4198568 2 34 l regular file

$ find . -type f
./k
./l

Those  'du' commands cover only one file instead of all files.

$ find . -type f -exec du -acb {} +
34 ./k
34 total

$ find . -type f -print0 | du --files0-from=- -cb
34 ./k
34 total

Isn't rather *68* expected?

You probably want to specify --count-links if you want hardlinked files
(like your example k and l) to be considered by du as separate files:

    $ echo foo > k
    $ ln k l


    $ du -c k l
    4       k
    4       total

    $ du -c --count-links k l
    4       k
    4       l
    8       total

Yes, that's right. Closing the bug report.
