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).
