clri(1M)                                                 clri(1M)



     NAME
          clri - clear inode

     SYNOPSIS
          /etc/clri [-Tfile-system-type] file-system i-number ...

     DESCRIPTION
          clri zeros (clears) the inode numbered i-number and incre-
          ments the inode generation count.  The 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 show up as ``missing'' in an fsck(1M) of the file-
          system.  This command should only be used in emergencies,
          and extreme care should be exercised.

          The -T flag option indicates the file-system type, such as
          4.2 or 5.2.  If this option is not used, clri attempts to
          determine the file-system type.

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

          The primary purpose of this command is to remove a file that
          for some reason appears in no directory.  If it is used to
          ``zap'' an inode that does appear in a directory, care
          should be taken to track down the entry and remove it.  Oth-
          erwise, when the inode is reallocated to some new file, the
          old entry will still point to that file.  At that point, re-
          moving the old entry will destroy the new file.  The new en-
          try will again point to an unallocated inode, so the whole
          cycle is likely to be repeated again and again.

     EXAMPLE
               clri /dev/rdsk/c0d0s0 65

          where /dev/rdsk/c0d0s0 is a legitimate file system and 65 is
          the inode number to be cleared.

     WARNING
          This command should be used with caution.

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