cd /usr
touch 0101000000 * .*; find . -name '*' -type d -print | xargs -i echo touch 0101000000 '{}/* {}/.*' | sh -x

touch MMDDhhmm[YY] FILES...

no recursive option for touch!


	should not just change on /, 'cause all files including mounted volumes will be affected. What's worse, it will dive into directories such as /dev, /proc which is not supposed to be touched.

find . -name '*' -type d -print | xargs -ti touch 0101000000 '{}/*'

shows ok, but don't work. well, I just found out that actually it create the file '*' !

set -f dir * * find / -name '*' !! | xargs rm
