Seth showed me that the WFU Library lets you check out books on-line through NetLibrary. Well, they’ve got Learning the Bash Shell on-line, and well, bash is the default shell for Red Hat. So I read some of it yesterday, and then went through the first half of the info docs (info bash) last night and this morning.
The resulting options added to my .bashrc are
shopt -s cdspell
# physical directories only
set -P
export CDPATH=~:~/cvs
PROMPT_COMMAND='echo -ne "�33]0;${USER}@${HOSTNAME%%.*}:${PWD/#$HOME/~}${STATUS:+" "}${STATUS}�07"'
