Delete command line history permanently?

How can I delete the whole command line history permanently?

cat /dev/null > ~/.bash_history && history -c && exit

seems not to work as there is no ~/.bash_history file.

Also, if there is a way, how can I make this automatically evertime I logout from command line?

Thank you in advance.

Delete

/storage/.ash_history

Thank you, this works for a one-time erase. But what I really want is to disable history completely.

The command

echo $HISTFILE

gives me the following output

/storage/.ash_history

so I've tried the following command which is being executed without any error

unset HISTFILE

but after exit and login via SSH the /storage/.ash_history file is being created again.

Well, after messing around with this a while now I did not found the solution but I want to share my workaround with you which will delete the according history file on every system startup, system halt, system reboot and system poweroff/shutdown:

According to this tutorial I have created the two files autostart.sh and shutdown.sh inside the /storage/.config folder:

Content of autostart.sh:

(  rm -rf /storage/.ash_history;
) &

Contect of shutdown.sh:

case "$1" in
    halt)
    # your commands here
    ;;
    poweroff)
    # your commands here
    ;;
    reboot)
    # your commands here
    ;;
    *)
    rm -rf /storage/.ash_history
    ;;
esac

After creating those files with the according content make both files executable:

chmod +x /storage/.config/autostart.sh
chmod +x /storage/.config/shutdown.sh

Maybe this helps someone else but me too.
