In this case, named pipes do exactly the same thing like normal pipes except that they leave stuff in the file system that you later need to rm. If you want to split it, I say use normal pipes and simply spread the commands across multiple lines. Anyway, I'm glad it worked.

Still you might need to close the writing ends so that reading can finish. Why don't you simply pipe it like this: convert rose: -resize 640x480\! png:fd:1 | convert png:fd:0 win: and completely get rid of the named pipe?

You probably want an & after convert rose: -resize 640x480\! png:fd:3

It appears to work for -o too. I tried creating a simple archive with and without --owner root:root and then diffed their respective hexdumps. What changed were two two-byte sequence that little-endian-decoded to 0 and my $UID respectively.

Thanks. It does the job, though only partly. Looks like cpio (which seems to always encode uids numerically) can anonymize its archives fully via the --owner switch.
