SYNOPSIS         top

       systemd-suspend.service

       systemd-hibernate.service

       systemd-hybrid-sleep.service

       systemd-suspend-then-hibernate.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 and pulled in by
       suspend-then-hibernate.target to execute system suspend with a
       timeout that will activate hibernate later.

       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", "hybrid-sleep", or
       "suspend-then-hibernate" 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 react to system
       suspend/hibernation and resume, they should rather use the Inhibitor
       interface[1].

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

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