CLRI(8)                 GENIX Programmer's Manual                 CLRI(8)



      NAME
           clri - clear i-node

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

      DESCRIPTION
           N.B.: Clri is obsoleted  for  normal  file  system  repair  work  by
           fsck(8).

           Clri writes zeros on the i-nodes with the decimal i-numbers  on  the
           filesystem.   After  clri, any blocks in the affected file will show
           up as `missing' in an icheck(1) of the filesystem.

           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 zap 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.

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