This is possible in bash (assuming I understand correctly).  Below is
the relevant portion of my .bashrc -- all my history-related config is
here, it's not all needed for the shared history command "stuff":


# make a multi-line cmd into one line in history
shopt -s cmdhist

# don't put duplicate lines in the history. See bash(1) for more options
export HISTCONTROL=ignoredups
# ... and ignore same sucessive entries.
export HISTCONTROL=ignoreboth

# set up the prompt:
promptCommand() {
    # save the current history to disk on each command (this enables
on-the-fly history sharing between terminals)
    history -a

    ## Snipped a bunch of stuff to set a PS1 based on system status.
}
export PROMPT_COMMAND=promptCommand
