Question

I want to get my bash command history as many as possible, I find ./bash_history only contains most recent two thousands lines, does it mean the ones before that is lost forever? Is there anyway to get it back.

Thanks a lot.

I’m afraid your past history is lost forever. But you can preserve it in the future. Increasing $HISTSIZE and $HISTFILESIZE helps, but if you really want to keep all your commands forever, check out this tip.
