RECREATING DIRECTORY TREES

This problem frequently
occurs. There is a machine
with a complex directory
structure, and you want to
have a copy of this directory
tree on another machine.

It is for testing purposes
(for example), and you want
to copy permissions,
UID/GID, and the directory
tree but don't want to copy
user files.

Here is the fastest
solution:
machine_a # cd /mydir
machine_a # find . -depth -print | cpio -o -O /tmp/dir.cpio

Copy the dir.cpio to
another machine.

machine_b # mkdir /mydir ; cd /mydir
machine_b # cat /tmp/dir.cpio | cpio -id
