SYSTEMD-RUN(1)                    systemd-run                   SYSTEMD-RUN(1)

NAME
       systemd-run - Run programs in transient scope or service or timer units
SYNOPSIS
       systemd-run [OPTIONS...] COMMAND [ARGS...]
       systemd-run [OPTIONS...] [TIMER OPTIONS...] {COMMAND} [ARGS...]
DESCRIPTION
       systemd-run may be used to create and start a transient .service or a
       transient .timer 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 with timer options, transient timer unit also be
       created with transient service unit. But the transient timer unit is
       only started immediately. The transient service unit will be started
       when the transient timer is elapsed. If --unit= is specified with timer
       options, the COMMAND can be omitted. In this case, systemd-run assumes
       service unit is already loaded and creates transient timer unit only.
       To successfully create timer unit, already loaded service unit should
       be specified with --unit=. This transient timer unit can activate the
       existing service unit like any other timer.
       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:
       --scope
           Create a transient .scope unit instead of the default transient
           .service unit.
       --unit=
           Use this unit name instead of an automatically generated one.
       --property=, -p
           Sets a unit property for the scope or service unit that is created.
           This takes an assignment in the same format as systemctl(1)'s
           set-property command.
       --description=
           Provide a description for the service or scope 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 or scope 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 or service 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).
       --service-type=
           Sets the service type. Also see Type= in systemd.service(5). This
           option has no effect in conjunction with --scope. Defaults to
           simple.
       --uid=, --gid=
           Runs the service process under the UNIX user and group. Also see
           User= and Group= in systemd.exec(5).
       --nice=
           Runs the service process with the specified nice level. Also see
           Nice= in systemd.exec(5).
       --setenv=
           Runs the service process with the specified environment variables
           set. Also see Environment= in systemd.exec(5).
       --pty, -t
           When invoking a command as service connects its standard input and
           output to the invoking tty via a pseudo TTY device. This allows
           invoking binaries as services that expect interactive user input,
           such as interactive command shells.
       --quiet, -q
           Suppresses additional informational output while running. This is
           particularly useful in combination with --pty when it will suppress
           the initial message explaining how to terminate the TTY connection.
       --on-active=, --on-boot=, --on-startup=, --on-unit-active=,
       --on-unit-inactive=
           Defines monotonic timers relative to different starting points.
           Also see OnActiveSec=, OnBootSec=, OnStartupSec=, OnUnitActiveSec=
           and OnUnitInactiveSec= in systemd.timer(5). This options have no
           effect in conjunction with --scope.
       --on-calendar=
           Defines realtime (i.e. wallclock) timers with calendar event
           expressions. Also see OnCalendar= in systemd.timer(5). This option
           has no effect in conjunction with --scope.
       --timer-property=
           Sets a timer unit property for the timer unit that is created. It
           is similar with --property but only for created timer unit. This
           option only has effect in conjunction with --on-active=,
           --on-boot=, --on-startup=, --on-unit-active=, --on-unit-inactive=,
           --on-calendar=. This takes an assignment in the same format as
           systemctl(1)'s set-property command.
       -G, --collect
           Unload the transient unit after it completed, even if it failed.
           Normally, without this option, all units that ran and failed are
           kept in memory until the user explicitly resets their failure state
           with systemctl reset-failed or an equivalent command. On the other
           hand, units that ran successfully are unloaded immediately. If this
           option is turned on the "garbage collection" of units is more
           aggressive, and unloads units regardless if they exited
           successfully or failed. This option is a shortcut for
           --property=CollectMode=inactive-or-failed, see the explanation for
           CollectMode= in systemd.unit(5) for further information.
       --system
           Talk to the service manager of the system. This is the implied
           default.
       -H, --host=
           Execute the operation remotely. Specify a hostname, or a username
           and hostname separated by "@", to connect to. The hostname may
           optionally be suffixed by a container name, separated by ":", which
           connects directly to a specific container on the specified host.
           This will use SSH to talk to the remote machine manager instance.
           Container names may be enumerated with machinectl -H HOST.
       -M, --machine=
           Execute operation on a local container. Specify a container name to
           connect to.
       -h, --help
           Print a short help text and exit.
       --version
           Print a short version string and exit.
       All command line arguments after the first non-option argument become
       part of the command line 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.
EXAMPLES
       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

       The following command invokes the updatedb(8) tool, but lowers the
       block IO weight for it to 10. See systemd.resource-control(5) for more
       information on the BlockIOWeight= property.
           # systemd-run -p BlockIOWeight=10 updatedb
       The following command will touch a file after 30 seconds.
           # date; systemd-run --on-active=30 --timer-property=AccuracySec=100ms /bin/touch /tmp/foo
           Mon Dec  8 20:44:24 KST 2014
           Running as unit run-71.timer.
           Will run as unit run-71.service.

           Dec 08 20:44:48 container systemd[1]: Started /bin/touch /tmp/foo.
       The following command invokes /bin/bash as a service passing its
       standard input, output and error to the calling TTY.
           # systemd-run -t /bin/bash
