44175ecf65Smycroftis obsoleted for normal file system repair work by

50175ecf65Smycrofton the filesystem residing on the given
51175ecf65Smycroft.Ar special_device .
52175ecf65SmycroftThe
53175ecf65Smycroft.Xr fsck 8
54175ecf65Smycroftutility is usually run after
55e40e4b2aSlukem.Nm
56175ecf65Smycroftto reclaim the zero'ed inode(s) and the
57175ecf65Smycroftblocks previously claimed by those inode(s).
58175ecf65SmycroftBoth read and write permission are required on the specified
59175ecf65Smycroft.Ar special_device .

61175ecf65SmycroftThe primary purpose of this routine
62175ecf65Smycroftis to remove a file which
63175ecf65Smycroftfor some reason is not being properly handled by
64175ecf65Smycroft.Xr fsck 8 .
65175ecf65SmycroftOnce removed,
66175ecf65Smycroftit is anticipated that
67175ecf65Smycroft.Xr fsck 8
68175ecf65Smycroftwill be able to clean up the resulting mess.
