Od is the husband of Freyja, and likely a predecessor for the more commonly-known Odin. He is, like Odin, a God of both war and wisdom, but little more is known. He disappeared inexplicably, for which his wife cried golden tears.

od (Octal Dump) is a standard Unix command line utility. It shows a byte per byte representation of any file.

Is useful at least in two contexts, when you want to see what's inside a binary data file (to reverse engineering it, let's say) and when you want to know exactly which ASCII byte codes are written on a text file.

The GNU implementation was written by Jim Meyering and as usual with GNU programs it has a enormous number of argument options.

In its default mode it prints 16 bytes of the file per line, in 8 octal numbers coding two bytes of input each, with the file offset of the input at the beginning of each output line.

You can change the base of the output (octal, hexadecimal, decimal, backslashed escaped non-printable ASCII characters,...), and the representation of the data (bytes, shorts, longs...).

In optometry and ophthalmology, O.D. stands for oculus dexter, which is Latin for the right eye.
