systemctl-unset-environment

systemctl unset-environment VARIABLE...

systemctl unset-environment removes environment variables from the systemd service manager's environment. This undoes the effect of `systemctl set-environment`.Services started after the unset will not receive the removed variables.

--user

Unset in user service manager environment

Unset in system manager environment (default)

Only affects services started after the change. Already running services keep their environment. Changes are temporary and lost on reboot.

The unset-environment subcommand complements `set-environment`, providing complete runtime control over the service manager's environment.
