34.Sh NAME
35.Nm clri
36.Nd clear an inode
37.Sh SYNOPSIS
38.Nm
39.Ar special_device inode_number ...
40.Sh DESCRIPTION
41.Bf -symbolic
42The
43.Nm
44utility is obsoleted for normal file system repair work by
45.Xr fsck 8 .
46.Ef
47.Pp
48The
49.Nm
50utility zeroes out the inodes with the specified inode number(s)
51on the file system residing on the given
52.Ar special_device .
53The
54.Xr fsck 8
55utility is usually run after
56.Nm
57to reclaim the zeroed inode(s) and the
58blocks previously claimed by those inode(s).
59Both read and write permission are required on the specified
60.Ar special_device .
61.Pp
62The primary purpose of this routine
63is to remove a file which
64for some reason is not being properly handled by
65.Xr fsck 8 .
66Once removed,
67it is anticipated that
68.Xr fsck 8
69will be able to clean up the resulting mess.
70.Sh SEE ALSO
71.Xr fsck 8 ,
72.Xr fsdb 8
73.Sh HISTORY
74The
75.Nm
76utility first appeared in
77.At v6 .
78.Sh BUGS
79If the file is open, the work of
80.Nm
81will be lost when the inode is written back to disk from the inode cache.
