10: DESCRIPTION od__
11: dumps
12: file____
13: in
14: one or more formats
15: as
16: selected by the first argument.
17: (If the first argument is missing, -o__ is default.)
18: The meanings of the format argument characters
19: are:
20:
21: .in +5
22: .ti -2
23: a_ interprets words as PDP-11 instructions and
24: dis-assembles the operation code.
25: Unknown operation codes print as ???.
26:
27: .ti -2
28: b_ interprets bytes in octal.
29:
30: .ti -2
31: c_ interprets bytes in ascii.
32: Unknown ascii characters are printed as \\?.
33:
34: .ti -2
35: d_ interprets words in decimal.
36:
37: .ti -2
38: h_ interprets words in hex.
39:
40: .ti -2
41: o_ interprets words in octal.
42:
43: .in -5
44: The file argument specifies which file is to be dumped.
45: If no file argument is specified,
46: the standard input is used.
47: Thus od can be used as a filter.
48:
49: The offset argument specifies the offset
50: in the file where dumping is to commence.
51: This argument is normally interpreted
52: as octal bytes.
53: If '.' is appended, the offset is interpreted in
54: decimal.
55: If 'b' is appended, the offset is interpreted in blocks.
56: (A block is 512 bytes.)
57: If the file argument is omitted,
58: the offset argument must be preceded by '+'.
59:
60: Dumping continues until an end-of-file
61: condition or until
62: halted by sending an interrupt signal.
