tar problem (duplicate files)

[Dario Spagnolo]

Hi folks,


this morning I ran into a really strange problem. I'm not sure it's a bug, but
this list seemed the most appropriate.

Here is my output :

$ find /home/mm -size -100k > mm-files

$ wc -l mm-files
        955 mm-files

(these files take 6.6 Mb)

$ tar -cvf mm.tar -T mm-files

$ tar -tvf mm.tar | wc -l
        4677

$ ll -h mm.tar
-rw-r--r--    1 spada     spada          19M Jun 23 10:16 mm.tar

$ tar -tvf mm.tar | grep "blog/s4.zip"
-rwxrwxrwx mm/ftp_only    23233 2003-04-05 14:04:10 home/mm/blog/s4.zip
-rwxrwxrwx mm/ftp_only    23233 2003-04-05 14:04:10 home/mm/blog/s4.zip
-rwxrwxrwx mm/ftp_only    23233 2003-04-05 14:04:10 home/mm/blog/s4.zip


---------------------------

To recap :

I want to tar all files in /home/mm smaller than 100k. There are 955 files that
correspond to this criterion, they take 6.6Mb.
I tar them. I list the content of the archive and count the lines : 4677 files
instead of 955. The size differ from 6.6Mb to 19M.
I then list the content of the archive filtering out everything except the file
s4.zip. This file appears 3 times in the archive !! :)


Do I need a psychanalist ? :-)

Thank you for your patience guys !
