XD is yet another program to display a binary file as a series of hexadecimal bytes and characters. What makes XD special, though, is its ability to display a file as a set of simple structured records (example). It can also convert a text file to its binary equivalent (example:
echo 3.14159|xd -wrf|xd -rL).
XD v1.20 (124k, 16- & 32-bit DOS and Win32 console binaries, C source).
