clri(1M) System Administration Commands clri(1M)NAME
clri, dcopy - clear inode
SYNOPSISclri [-F FSType] [-V] special i-number
dcopy [-F FSType] [-V] special i-number
DESCRIPTIONclri 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).
