I want up arrow to give the last command from that shell though. I'd like Ctrl+R to search all the full history, but I don't think bash can do that combination.

I want up arrow to give the last command from that shell though. I'd like Ctrl+R to search all the full history, but I don't think bash can do that combination. Also I just don't trust bash to actually keep my history, no matter what I do with HISTSIZE and HISTFILESIZE.

`histappend` probaby works the way you want it to. I have about a half dozen terminals open. I want to have the current shell's history seem consistent within any shell, but I want ^R in any NEW terminal to include all the commands entered in any terminal. shopt -s histappend HISTCONTROL=ignoredups:ignorespace # append to bash history Right Now export PROMPT_COMMAND="history -a" I share your distrust, though -- I've frequently lost my bash history for $REASONS (which another comment here seems to have answered :)) -- but the convenience of not having my shell history clobbered by which-shell-I-close-first is _amazing_.
