clearing commandline history

how would i clear my commandline history
at logon/logoff/startup time ??

it tried this : editing my /etc/rc.d/rc.local file like this
i know this is for system startup

Code:

#!/bin/sh
#
# /etc/rc.d/rc.local:  Local system initialization script.
#
# Put any local startup commands in here.  Also, if you have
# anything that needs to be run at shutdown time you can
# make an /etc/rc.d/rc.local_shutdown script and put those
# commands in there.

#clear user history ~/.bash_history
echo "" > ~/.bash_history

#clear root history /root/.bash_history
echo "" > /root/.bash_history

but when i reboot, the history still remains.

where would i put the command to clear roots
commandline history(when using su / sudo) ??
i have these alias in /etc/profile:

Code:

alias exit='history -c ~/.bash_history && history -c /root/.bash_history && exit'
alias clear='history -c ~/.bash_history && history -c /root/.bash_history && clear'
