The only related option is -L, but it is to be used for symbolic links (and turns them into regular files). If you need this functionality, you'll probably be better off with tar, or you put tar archives into a cpio pipeline... Keep in mind not all archiving, compressing and transmission tools share the same amount of dedication toward the file system features (links, modes, user:group, permissions, attributes and so on). In case of cpio, I just think the requested feature simply is not part of what cpio can do (unlike tar, as you've correctly mentioned). -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
