NAME
clri - clear i-node
SYNOPSIS
/etc/clri filesystem i-number ...
DESCRIPTION
Clri writes zeros on the i-nodes with the decimal i-numbers on the
filesystem. After clri, any blocks in the affected file will show up
as `missing' in an icheck(8) of the filesystem.
Read and write permission is required on the specified file system de‐
vice. The i-node becomes allocatable.
The primary purpose of this routine is to remove a file which for some
reason appears in no directory. If it is used to clear an i-node which
does appear in a directory, care should be taken to track down the en‐
try and remove it. Otherwise, when the i-node 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 i-node, so the cycle is likely to be re‐
peated.
Clri is obsoleted for normal file system repair work by fsck(8).

BUGS
If the file is open, clri is likely to be ineffective.
