work on $x extracts (clumsily) the hexadecimal pairs after the first colon with a space after it, and then precede each pair with an 'x'.

work on $c to remove hex pairs after a colon preceded by hex chars and then remove any new lines.

Then print the result in a formatted way.

My guess is that this code could be replaced by one regexp (2 tops), but without seeing data I can't recommend the best way to approach.
