Try "man ascii" if you want to know their names, although this
is of no use in your task.

Try "man tr" for the obvious tool to use; obviously it's trivial
to do with any of the standard Unix tools such as awk, although
the more modern kitchen sink languages will also be able to
assist.

Why not have a go at solving it and then come back with a report
of what you tried and what you got if you still need help?

You'd certainly piss me off much less if you found out where the
Enter key is so that you could limit your lines to less than 75
characters.

Cheers, Greg
