in thread Usage of a sparse file

Hi, as I noted in my original post,the information retrieved from stat is not usable, as it returns the blocks used by the full size of the sparse file, not actual usage size

Thanks though!

    Isn't blocks*blocksize = (stat $file)[11]*512 the actual used size? 
    $ ls -lh sparse_file
-rw-r--r-- 1 aitap aitap 101M Mar 11 20:30 sparse_file
$ du -h sparse_file
1,1M    sparse_file
$ du -B 1 sparse_file 
1060864 sparse_file
$ perl -E'say ((stat shift)[12]*512)' sparse_file
1060864

    Sorry if my advice was wrong.

      Hm, that works. I can grab the blocksize as well, and divide by 8 to get down to 512. Thanks!
