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).
