I don't know why I would read a redhat.com web page to learn about Debian or Ubuntu. I'm aware that there's a "bash-builtins" package in Debian which provides them (for Debian's version of bash). However, xmb's question was about "bash dev", which I'm reading as "bash compiled from source code". If one is building bash from source, then the loadable builtins would also need to be built and installed before they can be used.
