NAME            od  --  octal dump

SYNOPSIS        od [ -abcdho ] [ file ] [ [+]offset[.][b] ]

DESCRIPTION     od dumps file in one or more formats as selected

                by the first argument.  (If the first argument is

                missing, -o is default.)  The meanings of the

                format argument characters are:

                   a interprets words as PDP-11 instructions and

                     dis-assembles the operation code.  Unknown

                     operation codes print as ???.

                   b interprets bytes in octal.

                   c interprets bytes in ascii.  Unknown ascii

                     characters are printed as \?.

                   d interprets words in decimal.

                   h interprets words in hex.

                   o interprets words in octal.

                The file argument specifies which file is to be

                dumped.  If no file argument is specified, the

                standard input is used.  Thus od can be used as a


                The offset argument specifies the offset in the

                file where dumping is to commence.  This argument

                is normally interpreted as octal bytes.  If '.'

                is appended, the offset is interpreted in deci-

                mal.  If 'b' is appended, the offset is inter-

                preted in blocks.  (A block is 512 bytes.)  If

                the file argument is omitted, the offset argument

                must be preceded by '+'.

                Dumping continues until an end-of-file condition

                or until halted by sending an interrupt signal.
