clri - Clears i-nodes
The clri command is obsoleted for normal file system
repair work by the fsck command.
The clri command writes zeros on the i-nodes with the decimal
i-numbers on the specified filesystem. After clri
has finished its work, any blocks in the affected file are
defined as "missing" when you run icheck on the filesystem.
Read and write permission is required on the specified
file system device. The i-node becomes allocatable.
The primary purpose of this routine is to remove a file
which does not appear in any directory. If you use the
command to remove an i-node which does appear in a directory,
take care to track down the entry and remove it.
Otherwise, when the i-node is reallocated to some new
file, the old entry will still point to that file. If you
then remove the old entry, you will destroy the new file,
and the new entry will again point to an unallocated inode.
Consequently, the entire cycle repeats itself.
You must be root to use this command. #endif
If the file is open, clri is likely to be ineffective.
