CLRI(8)                     System Manager's Manual                    CLRI(8)

       clri - clear inode

       /usr/etc/clri filesystem i-number...

       Note:  clri  has  been superseded for normal file system repair work by

       clri writes zeros on the inodes  with  the  decimal  i-numbers  on  the
       filesystem.   After  clri, any blocks in the affected file will show up
       as ``missing'' in an icheck(8) of the filesystem.

       Read and write permission is required  on  the  specified  file  system
       device.  The inode 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 zap  an  inode  which
       does  appear  in  a  directory,  care should be taken to track down the
       entry and remove it.  Otherwise, when the inode 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 inode, so the whole cycle is likely to be
       repeated again and again.

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