Slack space. Because files don't take up partial blocks in ext2/3, there are two different filesizes. The one seen by du is the number of bytes in the file. The one seen by dh is the number of blocks taken up (times the blocksize, of course). So, given a blocksize of 1024 bytes, an 800 byte file takes up 1024 bytes. A 5 byte file takes up 1024 bytes. Some of the newer filesystems such as Reiserfs try to fix this by putting all the little tails in a single block. -- Marshal Newrock, unemployed Linux user in Lansing, MI Caution: Product will be hot after heating -- [EMAIL PROTECTED] mailing list
