  Well, since "tr" deletes NULLs from its input, you could do "tr '' '' <
filename > filename.nonulls".

  Then again, "sed" apparently also deletes NULLs, so you could do something
similar with it: "sed -n p < filename > filename.nonulls".

  Both of those solutions are pretty much just hacks that rely on the fact
that tr and sed delete NULLs.  There's probably a more correct (i.e. it's
doing what it's doing explicitly, rather than relying on a fluke in a program)
solution in perl, but I'm religiously against posting perl scripts to the net,
since so many other people do it so much better than I :-).
