NAME         top

       systemd-suspend.service, systemd-hibernate.service, systemd-hybrid-
       sleep.service, systemd-sleep - System sleep state logic

SYNOPSIS         top

       systemd-suspend.service

       systemd-hibernate.service

       systemd-hybrid-sleep.service

       /usr/lib/systemd/system-sleep

DESCRIPTION         top

       systemd-suspend.service is a system service that is pulled in by
       suspend.target and is responsible for the actual system suspend.
       Similarly, systemd-hibernate.service is pulled in by hibernate.target
       to execute the actual hibernation. Finally,
       systemd-hybrid-sleep.service is pulled in by hybrid-sleep.target to
       execute hybrid hibernation with system suspend.

       Immediately before entering system suspend and/or hibernation
       systemd-suspend.service (and the other mentioned units, respectively)
       will run all executables in /usr/lib/systemd/system-sleep/ and pass
       two arguments to them. The first argument will be "pre", the second
       either "suspend", "hibernate", or "hybrid-sleep" depending on the
       chosen action. Immediately after leaving system suspend and/or
       hibernation the same executables are run, but the first argument is
       now "post". All executables in this directory are executed in
       parallel, and execution of the action is not continued until all
       executables have finished.

       Note that scripts or binaries dropped in
       /usr/lib/systemd/system-sleep/ are intended for local use only and
       should be considered hacks. If applications want to be notified of
       system suspend/hibernation and resume, there are much nicer
       interfaces available.

       Note that systemd-suspend.service, systemd-hibernate.service, and
       systemd-hybrid-sleep.service should never be executed directly.
       Instead, trigger system sleep states with a command such as
       "systemctl suspend" or similar.

       Internally, this service will echo a string like "mem" into
       /sys/power/state, to trigger the actual system suspend. What exactly
       is written where can be configured in the "[Sleep]" section of
       /etc/systemd/sleep.conf or a sleep.conf.d file. See
       systemd-sleep.conf(5).

OPTIONS         top

       systemd-sleep understands the following commands:

       -h, --help
           Print a short help text and exit.

       --version
           Print a short version string and exit.

       suspend, hibernate, hybrid-sleep
           Suspend, hibernate, or put the system to hybrid sleep.
