Bash: keep some commands in history for current session only

Question

My HISTIGNORE var:

export HISTIGNORE="&:[bf]g:exit:mc:htop:top:clear:reset:histoty *:df *:du *:kill *:pkill *:pushd *:popd:bash *:yaourt *:pacman *:upd"

All what i want is to keep these commands in history for current bash session and to ignore them in subsequent sessions. Other commands (not in the HISTIGNORE) should be in .bash_history file. Example (pushd in $HISTIGNORE, cd not)

pushd /home/
(Ctrl-R)push(Enter) -> pushd /home
cd /usr/src
bash
(Ctrl-R)push(Enter) -> (Anything but pushd)
(Ctrl-R)cd(Enter) -> cd /usr/src

Is there any solutions for these problem?

Answer 1

Simple solution is to just set the HISTIGNORE to nothing for the current session at the beginning,

export HISTIGNORE=""

and then set it back again for other session by adding it to .bashrcfile
