63 | ||
2614202b | 64 | <para><command>systemd-run</command> may be used to create and start |
3803cde4 LP |
65 | a transient <filename>.service</filename> or a |
66 | <filename>.scope</filename> unit and run the specified | |
67 | <replaceable>COMMAND</replaceable> in it.</para> | |
68 | ||
69 | <para>If a command is run as transient service unit, it will be | |
70 | started and managed by the service manager like any other service, | |
71 | and thus show up in the output of <command>systemctl | |
72 | list-units</command> like any other unit. It will run in a clean | |
73 | and detached execution environment. <command>systemd-run</command> | |
74 | will start the service asynchronously in the background and | |
75 | immediately return.</para> | |
76 | ||
77 | <para>If a command is run as transient scope unit, it will be | |
78 | started directly by <command>systemd-run</command> and thus | |
79 | inherit the execution environment of the caller. It is however | |
80 | managed by the service manager similar to normal services, and | |
81 | will also show up in the output of <command>systemctl | |
82 | list-units</command>. Execution in this case is synchronous, and | |
83 | execution will return only when the command finishes.</para> | |
