|
|
<para><command>systemd-run</command> may be used to 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>
