Better to make an archive of it and copy the archive:
Code:
cd /usr
tar -czf /mnt/us/factutil.tgz local
Then move the archive from the top level of visible USB storage to top level of visible USB storage on the other device.
Code:
cd /usr
tar -xzf /mnt/us/factutil.tgz
That way ownerships and permissions are preserved, which would not be if you just copied the files to FAT-32 and then back again.
