google ... http://www.gnu.org/software/cpio/manual/cpio.html#Copy_002dpass-mode There are more simple ways to achieve this, but: xorriso -osirrox on -overwrite off \ -outdev stdio:/dev/null \ -map /u/test/cdrskin-1.3.2 /foo \ -extract /foo /u/test/copy_of_cdrskin-1.3.2 \ -rollback_end diff -r /u/test/cdrskin-1.3.2 /u/test/copy_of_cdrskin-1.3.2 rm -r /u/test/copy_of_cdrskin-1.3.2 This gesture is uneconomic because libisofs will build a complete directory tree of /foo in memory before xorriso can extract the not-yet-committed files from disk to disk. The best use case for such pack-unpack combinations is out of reach for xorriso, anyway, because ISO 9660 needs random access. Thus an ISO image cannot always be read from a pipe. So xorriso cannot transmit over the net to another xorriso which would unpack on the fly. bsdtar does read from pipe and thus happily fails when confronted with a multi-session ISO, where directories are stored after older file content. Since we have a single session ISO here, it could serve as receiver and unpacker for a xorriso generated ISO. But we still have to invent a good use case for this. Have a nice day :) Thomas
