A directory entry (filename) points to an inode, which directly and indirectly points to the logical blocks inside the partition. There are no references for the way back. So the only way to find out is to traverse the directorys and inodes until you have found the inode and then to continue with the directorys until you found all remaining directory enties. -- B.Walter COSMO-Project http://www.cosmo-project.de ticso@cicely.de Usergroup info@cosmo-project.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
