That's roughly what I use, too.. except that I've taken to using xargs
instead of --exec. When using --exec, an instance of perl is
instantiated for every file found. Not too big a deal if there aren't
very many files, but it can be a bear if there are.

find $TOPDIR -type f -print0 | xargs -0 perl -pi.bak -e
's,&10\.10\.0\.52&i,10.0.0.68,g'
