OD outputs the hex from right to left?...hex dump utility...

[Dave Arnold]

hi Doug,

ok, I think that might be what I'll have to do.
I was just looking for something quickly avaibable.
I know there's lots of utilities like this out on the net
but I just don't have much luck finding a match.

Currently I'm using Textpad and opening files in
binary mode which formats like the way I want.
Only thing is Textpad runs on windows and is
not very portable.

I've written a program like this before but just
was feeling a bit lazy.

I don't think the computer endian matters because
you just read() 1 byte at a time from the file and
printf() in the order they're read.  I don't know why
od is printing every 4 bytes in reverse when showing
the hex values.

Hi,

I would suggest either of the following:

1.  your requirements are so narrow and specific you could probably
     write a tool to do what you want, in C or Perl, in less than an hour.

2.  use a big-endian computer, so the bytes are in the order you want
     them (e.g. MC 68xxxx, or  the pending IA-64).

Doug Wyatt
