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

NAME
       clri - clear i-node

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

DESCRIPTION
       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(8) of the filesystem.

       Read  and write permission is required on the specified file system de‐
       vice.  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 clear an i-node which
       does  appear in a directory, care should be taken to track down the en‐
       try 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 cycle is likely to be re‐
       peated.

       Clri is obsoleted for normal file system repair work by fsck(8).

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