- NAME
- od - octal, decimal, hex, ascii, or floating point dump
-
- SYNTAX
- od [ -format ] [-bnnn] [-ennn] [ file_list ]
-
- DESCRIPTION
- Od displays the files in the file_list, or the standard input if a
- file_list missing, in one or more dump formats as selected by the
- format argument. The default format is "-sx".
-
- The meanings of the format argument characters are:
-
- c Dump as ascii characters. Tabs, backspaces, carriage returns,
- form feeds, and line feeds are displayed as \t, \b, \r, \f, and \n.
- All other non-printing characters are displayed as a hexadecimal
- byte.
-
- d Dump as signed decimal words ( 2 bytes ).
-
- u Dump as unsigned decimal words.
-
- o Dump as unsigned octal words.
-
- x Dump as unsigned hexadecimal words.
-
- f Dump as a floating point number ( 4 bytes ).
-
- l Extend precision to long size (i.e. words to long words (4 bytes)
- and floating point to double precision (8 bytes).) This does not
- affect the "c" format.
-
- s Lower precision to short size. This is only valid for integer words
- which are reduced to a byte size.
-
-
- The offset options are:
-
- -b The beginning offset argument specifies the byte offset into the
- file where dumping is to commence. The offset is a decimal number.
-
- -e The ending offset argument specifies the byte offset into the file
- where dumping will cease. The offset must be a decimal number.
-
- The displayed address is a long word in hexadecimal format.
-
- EXAMPLE:
- Display the first 100 bytes of a.out in long octal format.
-
- od -lo -e100 a.out
