objdump -s -j .rodata exefile
gives a side-by-side hex/printable ASCII dump of the contents of the rodata
section like:
Contents of section .rodata:
0000 67452301 efcdab89 67452301 efcdab89 gE#.....gE#.....
0010 64636261 68676665 64636261 68676665 dcbahgfedcbahgfe
It doesn’t look like there’s anything in there to control formatting, but it’s a start. You could always undump the hex and feed it to od, I suppose 🙂
