     od  -  octal dump


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


     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


     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 filter.

     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 decimal.  If `b' is appended, the offset

     is interpreted in blocks.  (A block is 512 bytes.)   If  the

     file  argument  is  omitted,  the  offset  argument  must be

     preceded by `+'.

     Dumping continues until end-of-file.
