clri -- Command Clear i-node /etc/clri filesystem inumber ... clri zeroes out each i-node with inumber on filesystem. filesystem is almost always a device-special file that corresponds to a disk device, e.g., /dev/rat0a or /dev/rsd1c. The raw device should be used. For example, the command /etc/clri /dev/rat0a 8250 clears i-node 8250 on the file system on device /dev/rat0a, which is the first partition on your first AT hard disk. The user must have read and write permission on the filesystem. If the file that inumber identifies is open, then clri probably will not work as you expect: the system maintains in core memory a copy of all active i-nodes, and the kernel will eventually write this copy to disk, thus undoing the action of clri. To ensure that this does not happen, unmount the file system before you running clri. If the i-node is for the root file system, reboot the system immediately after you run clri.
