Re^4: Usage of a sparse file

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!	[reply]
