NAME
       systemd-run - Run programs in transient scope or service units

SYNOPSIS
       systemd-run [OPTIONS...] COMMAND [ARGS...]

DESCRIPTION
       systemd-run may be used to create and start a transient .service or a .scope unit and run the specified COMMAND in it.

       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 systemctl list-units like any other unit. It will run in a clean and detached execution environment.  systemd-run will
       start the service asynchronously in the background and immediately return.

       If a command is run as transient scope unit, it will be started directly by systemd-run 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 systemctl
       list-units. Execution in this case is synchronous, and execution will return only when the command finishes.

OPTIONS
       The following options are understood:

       -h, --help
	   Prints a short help text and exits.

       --version
	   Prints a short version string and exits.

       --user
	   Talk to the service manager of the calling user, rather than the service manager of the system.

       --system
	   Talk to the service manager of the system. This is the implied default.

       --scope
	   Create a transient .scope unit instead of the default transient .service unit.

       --unit=
	   Use this unit name instead of an automatically generated one.

       --description=
	   Provide description for the unit. If not specified, the command itself will be used as a description. See Description= in
	   systemd.unit(5).

       --slice=
	   Make the new .service or .scope unit part of the specified slice, instead of the system.slice.

       --remain-after-exit
	   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 RemainAfterExit= in systemd.service(5).

       --send-sighup
	   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 SendSIGHUP= in systemd.kill(5).

       All command-line arguments after the first non-option argument become part of the commandline of the launched process. If a command is run
       as service unit, its first argument needs to be an absolute binary path.

EXIT STATUS
       On success, 0 is returned, a non-zero failure code otherwise.

EXAMPLE
       The following command will log the environment variables provided by systemd to services:

	   # systemd-run env
	   Running as unit run-19945.service.
	   # journalctl -u run-19945.service
	   Sep 08 07:37:21 bupkis systemd[1]: Starting /usr/bin/env...
	   Sep 08 07:37:21 bupkis systemd[1]: Started /usr/bin/env.
	   Sep 08 07:37:21 bupkis env[19948]: PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin
	   Sep 08 07:37:21 bupkis env[19948]: LANG=en_US.UTF-8
	   Sep 08 07:37:21 bupkis env[19948]: BOOT_IMAGE=/vmlinuz-3.11.0-0.rc5.git6.2.fc20.x86_64
