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.
