Install Bash by running the following commands: ./configure --prefix=/usr --with-curses && make && make install && logout mv -f $LFS/usr/bin/bash $LFS/usr/bin/bashbug $LFS/bin && &c6-chrootcmd; The static bash is replaced with the dynamic bash after we exit the chroot'ed environment, after which we re-enter it. We do this because it's better not to replace the static bash by a dynamic one when it's in use.
