    <title>Description</title>

    <para><command>systemd-run</command> may be used create and start
    a transient <filename>.service</filename> or a
    <filename>.scope</filename> unit and run the specified
    <replaceable>COMMAND</replaceable> in it.</para>

    <para>If a command is run as transient service unit, it will be
    started and managed by the service manager like any other service,
    and thus show up in the output of <command>systemctl
    list-units</command> like any other unit. It will run in a clean
    and detached execution environment. <command>systemd-run</command>
    will start the service asynchronously in the background and
    immediately return.</para>

    <para>If a command is run as transient scope unit, it will be
    started directly by <command>systemd-run</command> and thus
    inherit the execution environment of the caller. It is however
    managed by the service manager similar to normal services, and
    will also show up in the output of <command>systemctl
    list-units</command>. Execution in this case is synchronous, and
    execution will return only when the command finishes.</para>
