Описание (Description)
systemd-run may be used to create and start a transient .service
or .scope unit and run the specified COMMAND in it. It may also
be used to create and start a transient .path, .socket, or .timer
unit, that activates a .service unit when elapsing.
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 shows up in the output of systemctl list-units like any
other unit. It will run in a clean and detached execution
environment, with the service manager as its parent process. In
this mode, systemd-run will start the service asynchronously in
the background and return after the command has begun execution
(unless --no-block or --wait are specified, see below).
If a command is run as transient scope unit, it will be executed
by systemd-run itself as parent process and will thus inherit the
execution environment of the caller. However, the processes of
the command are managed by the service manager similar to normal
services, and will show up in the output of systemctl list-units.
Execution in this case is synchronous, and will return only when
the command finishes. This mode is enabled via the --scope switch
(see below).
If a command is run with path, socket, or timer options such as
--on-calendar= (see below), a transient path, socket, or timer
unit is created alongside the service unit for the specified
command. Only the transient path, socket, or timer unit is
started immediately, the transient service unit will be triggered
by the path, socket, or timer unit. If the --unit= option is
specified, the COMMAND may be omitted. In this case, systemd-run
creates only a .path, .socket, or .timer unit that triggers the
specified unit.
By default, services created with systemd-run default to the
simple type, see the description of Type= in systemd.service(5)
for details. Note that when this type is used the service manager
(and thus the systemd-run command) considers service start-up
successful as soon as the fork() for the main service process
succeeded, i.e. before the execve() is invoked, and thus even if
the specified command cannot be started. Consider using the exec
service type (i.e. --property=Type=exec) to ensure that
systemd-run returns successfully only if the specified command
line has been successfully started.
