dcopy


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 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/vfstab             List of default parameters for  each
                             file system
