[linux] cp owner (소유자) permit (권한) 같게 하는 옵션

해당 부분에 대한 옵션은

-pr 이었네요.

cp -pr  /home/src_home /home/tar_home

sudo cp -rp /home/my_home /media/backup/my_home

From cp manpage:

 -p     same as --preserve=mode,ownership,timestamps

 --preserve[=ATTR_LIST]
          preserve the specified attributes (default: mode,ownership,timestamps),
          if possible additional attributes: context, links, xattr, all
