CLRI(8)                                                   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 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 clear 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
          cycle is likely to be repeated.

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

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