NAME

       sleepctl - enable/disable sleepd

SYNOPSIS

       sleeptcl [on|off|status]

DESCRIPTION

       sleepctl  allows  temporarily  disabling of the sleepd(8) daemon, by a regular user. This can be useful when you're in the middle of a long
       download or compile, and don't want the system going to sleep in the middle.

       "sleepctl off" makes sleepd not put the system to sleep even if it thinks it is idle. If this command is run more than once,  the  requests
       stack up, and a like number of "sleepctl on" commands must be run to re-enable sleeping. This may be useful if multiple automated processes
       or users use the command. Note that the system may still be put to sleep for other reasons, such as a failing battery.

       "sleepctl on" re-enables sleeping. If sleeping is re-enabled and sleepd has seen no system activity for some time, and has  been  prevented
       from putting the system to sleep, it may put the system to sleep immediatly.

       "sleepctl status" outputs the current status of sleepd.

       Note  that  if  the  system is forced to sleep by other means, sleepd will not remember what mode it was in when it wakes back up, and will
       return to the default mode of putting the system to sleep after some amount of inactivity. This is by design, so you may easily	and  natu-
       rally undo the effects of a "sleepctl off" without remembering to turn it back on.

       This program communicates with sleepd by writing to the file /var/run/sleepd.ctl. As such, it needs read/write access to that file. It also
       needs to run as whatever user sleepd runs as, so it can hup the daemon.

EXAMPLES

	sleepctl off ; wget http://foo/huge.tgz ; sleepctl on

SYSTEMD-SUSPEND.SERVICE(8)				      systemd-suspend.service					SYSTEMD-SUSPEND.SERVICE(8)

NAME

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

SYNOPSIS

       systemd-suspend.service

       systemd-hibernate.service

       systemd-hybrid-sleep.service

       /usr/lib/systemd/systemd-sleep

DESCRIPTION

       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. See systemd-sleep.conf(5).

OPTIONS

       systemd-sleep understands the following commands:

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

       --version
	   Print the systemd version identifier and exit.

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