        !            15: .B N.B.:
        !            16: .I Clri
        !            17: is obsoleted for normal file system repair work by
        !            18: .IR fsck (8).
        !            19: .PP
        !            20: .I Clri
        !            21: writes zeros on the i-nodes
        !            22: with the decimal
        !            23: .I i-numbers
        !            24: on the
        !            25: .I filesystem.
        !            26: After
        !            27: .I clri,
        !            28: any blocks
        !            29: in the affected file
        !            30: will show up as `missing' in an
        !            31: .IR icheck (8)
        !            32: of the
        !            33: .I filesystem.
        !            34: .PP
        !            35: Read and write permission is required on the specified
        !            36: file system device.
        !            37: The i-node becomes allocatable.
        !            38: .PP
        !            39: The primary purpose of this routine
        !            40: is to remove a file which
        !            41: for some reason appears in no
        !            42: directory.
        !            43: If it is used to zap an i-node
        !            44: which does appear in a directory, care should be taken to track down
        !            45: the entry and remove it.
        !            46: Otherwise, when the i-node is reallocated to some new file,
        !            47: the old entry will still point to that file.
        !            48: At that point removing the old entry will destroy the new file.
        !            49: The new entry will again point to an unallocated i-node,
        !            50: so the whole cycle is likely to be repeated again and again.
        !            51: .SH "SEE ALSO"
        !            52: icheck(8)
        !            53: .SH BUGS
        !            54: If the file is open,
        !            55: .I clri
        !            56: is likely to be ineffective.
