     DESCRIPTION
	  Clri writes zeros on the 64 bytes  occupied  by  the	i-node
	  numbered  i-number.  File-system must be a special file name
	  referring to a device containing a file system.  After  clri
	  is executed, any blocks in the affected file will show up as
	  ``missing'' in an fsck(1) of the file-system.	 This  command
	  should  only	be used in emergencies and extreme care should
	  be exercised.

	  Read and write  permission  is  required  on	the  specified
	  file-system device.  The i-node becomes allocatable.

	  The primary purpose of this routine  is  to  remove  a  file
	  which	 for  some  reason  appears in no directory.  If it is
	  used to zero out an i-node which does appear in a directory,
	  care	should be taken to track down the entry and remove it.
	  Otherwise, when the i-node is reallocated to some new	 file,
	  the  old entry will still point to that file.	 At that point
	  removing the old entry will destroy the new file.   The  new
	  entry	 will  again  point  to	 an unallocated i-node, so the
	  whole cycle is likely to be repeated again and again.

	  fsck(1), fsdb(1), ncheck(1), fs(5).

     BUGS
	  If the file is open, clri is likely to be ineffective.
