NAME
       clri, dcopy - clear inode

SYNOPSIS
       clri [-F FSType] [-V] special i-number

       dcopy [-F FSType] [-V] special i-number

DESCRIPTION
       clri  writes  zeros  on the inodes with the decimal i-number on the file system stored on  special. After  clri, any blocks in the affected
       file show up as missing in an  fsck(1M) of special.

       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 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. 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.

       dcopy is a symbolic link to clri.

OPTIONS
       -F FSType       Specify the  FSType on which to operate.
			The  FSType should either be specified here or be determinable from  /etc/vfstab by matching  special with an entry in the
		       table, or by consulting /etc/default/fs.

       -V	       Echo the complete command line, but do not execute the command. The command line is generated  by  using  the  options  and
		       arguments  provided by the user and adding to them information derived from /etc/vfstab. This option should be used to ver-
		       ify and validate the command line.

USAGE
       See largefile(5) for the description of the behavior of clri and dcopy when encountering files greater than or equal to 2 Gbyte	(  2 **31
       bytes).

FILES
       /etc/default/fs	       Default local file system type

       /etc/vfstab	       List of default parameters for each file system
