                      2: .sh NAME
                      3: clri \*- clear i-node
                      4: .sh SYNOPSIS
                      5: .bd clri
                      6: i-number [ filesystem ]
                      7: .sh DESCRIPTION
                      8: .it Clri
                      9: writes zeros on the 32 bytes occupied by the i-node
                     10: numbered
                     11: .it i-number.
                     12: If the
                     13: .it "file system"
                     14: argument is given, the i-node resides on
                     15: the given device, otherwise on a
                     16: default file system.
                     17: The file system argument
                     18: must be a special file
                     19: name referring to a device
                     20: containing a file system.
                     21: After
                     22: .it clri,
                     23: any blocks
                     24: in the affected file
                     25: will show up as ``missing'' in a
                     26: .it check
                     27: of
                     28: of the file system.
                     29: .s3
                     30: Read and write permission is required on the specified
                     31: file system device.
                     32: The i-node becomes allocatable.
                     33: .s3
                     34: The primary purpose of this routine
                     35: is to remove a file which
                     36: for some reason appears in no
                     37: directory.
                     38: If it is used to zap an i-node
                     39: which does appear in a directory, care should be taken to track down
                     40: the entry and remove it.
                     41: Otherwise, when the i-node is reallocated to some new file,
                     42: the old entry will still point to that file.
                     43: At that point removing the old entry will destroy the new file.
                     44: The new entry will again point to an unallocated i-node,
                     45: so the whole cycle is likely to be repeated again and again.
                     46: .sh BUGS
                     47: Whatever the default file system is,
                     48: it is likely to be wrong.
                     49: Specify the file system explicitly.
                     50: .s3
                     51: If the file is open,
                     52: .it clri
                     53: is likely to be ineffective.
