HEXDUMP
Hexadecimal file dump

HEXDUMP is a C++ program which prints the contents of a file, byte by byte, in hexadecimal format.

This sort of information can be useful when determining the format of a file, checking for byte-swapping, or other common tasks.

On many computer systems, there's already a program called hexdump, so you have to be careful that you know which program you are running! You can type

which hexdump

Thanks to John McCabe of Rutgers for pointing out and correcting a bug which occurred on some machines if the byte value 0xFF was encountered, 30 January 2008.

Usage:

hexdump filename

reads filename and writes a hexadecimal dump to the standard output.

Sample Output:

        HEXDUMP: Hexadecimal dump of file: box.3ds.
