clri [-F FSType] [-V] special i-number
dcopy [-F FSType] [-V] special i-number
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.
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).
This command might not be supported for all FSTypes.
