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(8) 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.


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


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