.SH Name
clri \- clear inodes
.SH Syntax
.B /etc/clri
.I filesystem i-number ...
.SH Description
.NXR "clri command"
.NXA "clri command" "fsck command"
.NXR "inode" "clearing"
The
.PN clri
command has been superseded by 
.MS fsck 8
for normal file system repair work.
.PP
The
.PN clri
command writes zeros on the i-nodes with the decimal
.I i-numbers
on the
.I filesystem.
After
.PN clri ,
any blocks
in the affected file
will show up as `missing' in an
.MS icheck 8
of the
.I filesystem.
.PP
Read and write permission is required on the specified
file system device.
The i-node becomes allocatable.
.PP
The primary purpose of this command is to remove a file which
for some reason appears in no directory.
.NXR "file" "removing directoryless"
If it is used to zap an i-node
which does appear in a directory, care should be taken 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.
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 whole cycle is likely to be repeated again and again.
.SH Restrictions
If the file is open,
.PN clri
is likely to be ineffective.
