Well, to meet the problem at hand in /var/log: various log utilities
expect the existence of files, or will complain. So, the best solution
I've come up with (using Sam Hart's truncate suggestion) is:
find . -type f -exec truncate -s 0 {} \;
rm * might otherwise work well in most settings, but probably doesn't
meet the spec of the original one-liner problem statement. :-)
