I recieved many replies saying 'use od'. I did, it worked, thanks.
Here are a couple of perl scripts:
>From Darren Brechman-Toussaint
======================== cut here ================================
#!/opt/perl/perl
# Usage: xdump [file]
# Use the file they specified, if specified
open(STDIN,$ARGV[0]) || die "Can't open $ARGV[0]: $!\n" if $ARGV[0];
# Do it optimall as long as we can read 16 bytes at a time.
while (($len = read(STDIN,$data,16)) == 16)
{
@array = unpack('N4', $data);
$data =~tr/\0-\37\177-\377/./;
printf "%8.08x %8.08x %8.08x %8.08x %8.08x %s\n",$offset, @array,
$data;
$offset += 16;
}
# Now finish up the end a byte at a time.
if ($len)
{
@array = unpack('C*', $data);
$data =~y/\0-\37\177-\377/./;
for (@array)
{
$_ = sprintf('%2.2x', $_);
}
push(@array, ' ') while $len++ < 16;
$data =~ s/[^ -~]/./g;
printf "%8.08x ",$offset;
printf "%s%s%s%s %s%s%s%s %s%s%s%s %s%s%s%s %s\n",@array, $data;
}

Here ya go. A budding perl hacker, I whipped up a script for you :-)
I'd be interested in a summary...

# hexdump: writes an annoted hex dump of the form
