Thank you, I forgot about this...

OK, thank you for this hint too.
But first, I would like to know some basic things:
- How is the I/O redirection done for ksh93 builtins?
- How does ksh93 look for shared libs and how does it
find which builtin commands are inside a shared lib?
- How does ksh93 e.g. know to load libcmd and now does
it e.g. know that there is a b_ls() inside?
