systemctl-set-environment

Set environment variable

$ systemctl set-environment [VAR=value]

$ systemctl set-environment [VAR1=val1 VAR2=val2 ...]

$ systemctl set-environment [VAR=value] --user

systemctl set-environment VARIABLE=VALUE...

systemctl set-environment adds or updates environment variables in the systemd service manager's environment. These variables are passed to all services started after the change.
This is useful for injecting configuration into services without modifying their unit files.

--user

Set in user service manager environment

Set in system manager environment (default)

Only affects services started after the change. Changes are temporary and lost on reboot. Already running services are not affected. Use `import-environment` to import from the shell.

The set-environment subcommand enables dynamic environment configuration for services, complementing unit file Environment= directives.
