I have never had OS X work that way with the arrow up/down history, but I do enter this into my profile or similar:

PROMPT_COMMAND='history -a'
export HISTCONTROL="ignoredups"
export HISTIGNORE="&:ls:[bf]g:exit"

# -- shopt options, see shopt -p for all options --
shopt -s cdspell                                # Automatic spelling correction for `cd`
shopt -s cmdhist                                # Save multi-line cmd's as single line
shopt -s histappend                             # history list is appended to the file named by the value of the HISTFILE

Then I pretty control-R and have given a search though history possibility, that will bring up the last command that starts with the first few letters I typed in, I press control-R a few more times and it will cycle even deeper.

The settings above are pretty obvious, and do things like remove dupes in history, actually append the entries etc.  I have a pretty large .bash_history file that were someone to delete every again, thinking they were being cool by erasing their last commands, I would have to kill. :)

Is that what you are looking for?
