No, there is not.  Use cd command.

This is wrong.  Your command means "extract from the standard input all
files that match the globbing pattern "./bash".  Please, read the
documentation for a detailed description on the cpio invocation options
and arguments.

What you need to do in this case is

 rpm2cpio bash-4.1.7-1.fc13.i686.rpm | \
   (cd bash; cpio -imd --quiet --no-absolute-filenames)

Yes, of course.  This invocation is wrong.  The -i option instructs cpio
to run in copy-in mode and the -p tells it to run in copy-pass mode.

There's nothing weird.  You cannot require both copy-in and copy-pass
modes at the same time.  Please, read the docs.
