OD(1) General Commands Manual OD(1)
od - octal dump
od [ -bcdox ] [ 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 are:
b Interpret bytes in octal.
c Interpret bytes in ASCII. Certain non-graphic characters appear as
C escapes: null=\0, backspace=\b, formfeed=\f, newline=\n,
return=\r, tab=\t; others appear as 3-digit octal numbers.
d Interpret words in decimal.
o Interpret words in octal.
x Interpret words in hex.
The file argument specifies which file is to be dumped. If no file
argument is specified, the standard input is used.
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 of 512 bytes. If the
file argument is omitted, the offset argument must be preceded `+'.
Dumping continues until end-of-file.
