systemd-run

Run programs in transient units. More information: https://manned.org/systemd-run.

• Start a transient service:

sudo systemd-run {{command}} {{argument1 argument2 ...}}

• Start a transient service under the service manager of the current user (no privileges):

systemd-run --user {{command}} {{argument1 argument2 ...}}

• Start a transient service with a custom unit name and description:

sudo systemd-run --unit={{name}} --description={{string}} {{command}} {{argument1 argument2 ...}}

• Start a transient service that does not get cleaned up after it terminates with a custom environment variable:

sudo systemd-run --remain-after-exit --set-env={{name}}={{value}} {{command}} {{argument1 argument2 ...}}

• Start a transient timer that periodically runs its transient service (see man systemd.time for calendar event format):

sudo systemd-run --on-calendar={{calendar_event}} {{command}} {{argument1 argument2 ...}}
