Also judging by your blog you might like something like

    PROMPT_COMMAND="${PROMPT_COMMAND:+$PROMPT_COMMAND ; }"'echo $$ $USER \
                   "$(pwd) $(history 1)" >> ~/.bash_eternal_history'

in your .bashrc, so that you don't have to abuse the bash-history for keeping a lifetime of commands around.

Is it abuse? It hasn't slowed anything down yet.

Also, in the blog post I linked to the link you mention.

I don't know whether it's abuse. I just don't trust bash's history enough.

Yeah, I now noticed that you already put that link in the blog.

And to be clear, what's described in that link doesn't work, at least not on my OS X machine. Thus the code in my blog post.
