dcopy(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).
