History
For privacy you can turn off history:
Simply add the following to your (~/.bash_logout)
history -c
clear
This will cause bash to automatically clear your history on logout.
You can turn off history all together by setting:
HISTSIZE=0
HISTFILE="/dev/null"
SAVEHIST=0
export HISTSIZE HISTFILE SAVEHIST
This will cause bash to not record any history at all. However,
if you use just the .bash_logout you can continue to use history for
the current session.
