As someone already pointed out, bash stores the history in RAM
until it exits, but you can influence this behavior by placing
the following in your .bashrc file:
shopt -s histappend
export PROMPT_COMMAND='history -s'
This will force bash to append the history to the .bash_history
file and to update it whenever it displays a new prompt. This
will synchronize the history among all of your tabs in konsole.
