clri(1M)		System Administration Commands		      clri(1M)

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 de-
       vice. 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 de-
		       terminable from	/etc/vfstab by matching	 special  with
		       an  entry  in  the  table,  or  by  consulting /etc/de-
		       fault/fs.

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