Simple command line utility that displays file contents in binary. Example output: 0x0 01101000 01100101 01101100 01101100 0x4 01101111 00100000 01110111 01101111 0x8 01110010 01101100 01100100 00100000 0xC By default, hexadecimal offset addresses are printed in the left column. The '-r' option disables address printing, and removes the whitespace between columns. The '-n' option sets the number of bytes printed per line. If no file is specified, standard input is read.
