Just put:

export PROMPT_COMMAND='if [ "$(id -u)" -ne 0 ]; then echo "$(date "+%Y-%m-%d.%H:%M:%S") $(pwd) $(history 1)" >> "${HOME}/bash_logs_$(hostname)/bash-history-$(date "+%Y-%m-%d").log"; fi'

in your ~/.bash_profile. You also may need to `mkdir "${HOME}/bash_logs_$(hostname)"`

I took this command from a Hacker News thread of the past. I don't have a link to it any more.

There are several past posts with same bash one liner. For example https://news.ycombinator.com/item?id=14108671
