       powernap  -  have  the  system  "take  a power nap"; this can be a user
       defined  program  or  script  at  /etc/powernap/action,  or  the  first
       supported action among [suspend, hibernate, poweroff]


       powernap will run when powernapd(8) has determined that an action needs
       to be taken according to its configured parameters.

       If the file  /etc/powernap/action  is  executable,  then  the  powernap
       binary will run it when called.

       Otherwise, powernap will run one of:
         * pm-suspend
         * pm-hibernate
         *  poweroff  depending on your hardware’s capabilities, as determined
       by pm-is-supported(1).

       You may do one of:
         1)  Write  your  own  custom  at  /etc/powernap/action  and  make  it
         2) Replace /etc/powernap/action with an executable script or binary
         3)  Symlink  /etc/powernap/action  to some other executable script or


       /etc/powernap/action, /proc/acpi/sleep
