33.Sh NAME
34.Nm clri
35.Nd clear an inode
36.Sh SYNOPSIS
37.Nm
38.Ar special_device inode_number ...
39.Sh DESCRIPTION
40.Bf -symbolic
41The
42.Nm
43utility is obsoleted for normal file system repair work by
44.Xr fsck 8 .
45.Ef
46.Pp
47The
48.Nm
49utility zeroes out the inodes with the specified inode number(s)
50on the file system residing on the given
51.Ar special_device .
52The
53.Xr fsck 8
54utility is usually run after
55.Nm
56to reclaim the zeroed inode(s) and the
57blocks previously claimed by those inode(s).
58Both read and write permission are required on the specified
59.Ar special_device .
60.Pp
61The primary purpose of this routine
62is to remove a file which
63for some reason is not being properly handled by
64.Xr fsck 8 .
65Once removed,
66it is anticipated that
67.Xr fsck 8
68will be able to clean up the resulting mess.
69.Sh SEE ALSO
70.Xr fsck 8 ,
71.Xr fsdb 8
72.Sh HISTORY
73The
74.Nm
75utility first appeared in
76.At v6 .
77.Sh BUGS
78If the file is open, the work of
79.Nm
80will be lost when the inode is written back to disk from the inode cache.
