od - octal dump
od [ -abcdox ] [ file ] [ [ + ]offset[ . ][ b ] ]
_O_d dumps _f_i_l_e 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 _f_i_l_e 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 inter- preted 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.
