Start bash session without history

There are several options to disable saving commands to bash history e.g.

set +o history



How to start a new bash session with history disabled?

I tried bash +o history but it didn’t work.

EDIT: I don’t want to modify my rc or profile files. I just want to start a single bash session with a different configuration.

If you want to permanently disable history you can add shopt -u -o history or set +o history to your ~/.bashrc, or /etc/profile. Then clear your history!

history -c

Add the set +o history option in:


(it might change depending on the distro)

Then clear the history with:

history -c

Log off and log on again.

bash --init-file <(echo '. ~/.bashrc; unset HISTFILE')


bash --rcfile <(echo '. ~/.bashrc; unset HISTFILE')

And better put it in ~/.bash_aliases as permanent alias:

alias bash2="bash --init-file <(echo '. ~/.bashrc; unset HISTFILE')"

The simplest solution was posted in a comment, which I think should be one of the answers here

Execute this command to start a bash shell that does not save any commands to history :

export HISTFILE=

And commands in that session will not be saved. Commands in other terminal windows or sessions will still be saved as usual.
