Unix Tip #4514- July 21, 2025
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
