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
       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 verify and validate  the  com‐
		       mand 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
