How can I prevent Bash from writing history entries to disk? My
~/.bashrccontains the line
trap 'unset HISTFILE; exit' SIGHUP
but it doesn't have the desired effect. If I run
history -c && history -w; exit and open a new terminal, the history is empty, but if I type some more commands and exit, the commands are in the history when I open a new terminal. Any ideas?
