How to run an interactive script at KDE Plasma 5 startup?
How to add ssh keys to ssh agent?

KDE Plasma 5 allows to set startup scripts, see How to autostart programs on KDE Plasma 5.

I want to add my ssh keys at every startup to the ssh agent. However, the keys are encrypted and adding them to the agent requires a password. I need to type the password.

    konsole --workdir "$HOME" -e bash -c "$HOME/init_env.sh -i"
