<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>

<term><option>--remain-after-exit</option></term>
<listitem><para>After the service's process has terminated, keep
the service around until it is explicitly stopped. This is
useful to collect runtime information about the service after
it finished running. Also see

<term><option>--send-sighup</option></term>
<listitem><para>When terminating the scope unit, send a SIGHUP
immediately after SIGTERM. This is useful to indicate to
shells and shell-like processes that the connection has been
severed. Also see <varname>SendSIGHUP=</varname> in

needs to be an absolute binary path.</para>
