CLRI(1M)							      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 ta‐
		    ble, 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 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
