Actually there's another one that describes the process better in
my book, ``dtox''.

A perl one liner that would strip all trailing whitespace off lines might
be (trailing whitespace can cause some interesting and hard to find bugs
:-).

	perl -pe 's/\s+$/\n/'

Or if you want to edit a bunch of files in place, and keep copies:

	perl -i~ -pe 's/\s+$/\n/' file [file1 ...]

It is necessary for the welfare of society that genius should be
privileged to utter sedition, to blaspheme, to outrage good taste, to
corrupt the youthful mind, and generally to scandalize one's uncles.
