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