NAME
       rhd - a simple utility for dumping a file in hex

SYNOPSIS
       rhd [options] [file1] ... [fileN]

DESCRIPTION
       rhd is a simple utility for dumping the contents of files in hex. If no
       files are specified it dumps the contents of stdin.

       The output of rhd looks like:

                   00000000: 23 20 4d 61  6b 65 66 69 | # Makefi |
                   00000008: 6c 65 20 66  6f 72 20 68 | le for h |
                   00000010: 64 0a 23 20  24 49 64 3a | d.# $Id: |

       The first column lists the starting offset of the characters displayed
       on that line. This is followed by a dump of the hex values of the char-
       acters. Finally the ASCII representation of the hex values is dis-
       played. Unprintable characters are displayed as periods (.).

OPTIONS
       -c [chars]
              Dumps [chars] characters per line. The default is 16 characters.

       -s [offset]
              Starts the dump at offset [offset] in the file. By default rhd
              starts at the beginning of the file (offset 0). If [offset] is
              greater than the length of the file, no dump is produced.

       -e [offset]
              End the dump at offset [offset] in the file. The default behav-
              ior is to dump the entire file. If [offset] is greater than the
              length of the file, dumping stops at the end of the file. This
              option and the -l option are mutually exclusive.

       -l [len]
              Dumps [len] bytes. The default behavior is to dump the entire
              file. If [len] is greater than the length of the file, dumping
              stops at the end of the file. This option and the -e option are
              mutually exclusive.

       -v     Displays the version

       -h     Displays a help message

       -A     No ASCII - Prevents the output of the printable ascii string at
              the end of each line of the dump.

       -O     No Offset - Prevents the output of the file offset information
              at the beginning of every line.
