NAME
       hibernate - save your computer's state to disk, and then switch it off

SYNOPSIS
       hibernate [OPTION]...

DESCRIPTION
       The  hibernate script (or "suspend script") is used to invoke the Linux
       kernel's Hibernation functionality.

       When you hibernate your machine, the contents of your computer's memory
       will  be	 saved	to  disc, and your computer will switch off.  When you
       switch it back on again, it will resume exactly	as  it	was  when  you
       hibernated.   This  script  is  designed for TuxOnIce, which is not yet
       included in the main kernel tree and must be downloaded from the TuxOn‐
       Ice  web	 site  at  http://www.tuxonice.net/,  but can also utilise the
       vanilla	 kernel	  interfaces   for   swsusp   or    pmdisk    (through
       /proc/acpi/sleep	 or /sys/power/state).	Instructions on setting up the
       kernel can also be found on that web site.

       The hibernate script takes care of the user-space side of the  suspend,
       including unloading and reloading drivers which don't suspend properly,
       setting the system clock after resuming, taking down  and  bringing  up
       network interfaces and various other hacks that may be required on some
       hardware.  By default, all it does is restore the  system  clock	 after
       suspending;  see	 hibernate.conf(5)  for information on configuring the
       rest of its functionality.

       If the hibernate script is invoked with a name of the  form  hibernate-
       foo  then  it  will  use the configuration file /etc/hibernate/foo.conf
       instead of the default.

       The hibernate script accepts the following command-line options:

OPTIONS
       -h, --help      Shows this help screen.

       --version       Shows the Hibernate Script version.

       -f, --force     Ignore errors and suspend anyway.

       -k, --kill      Kill processes if needed, in order to suspend.

       -v<n>, --verbosity=<n>
		       Change verbosity level (0 = errors only, 3 = verbose, 4
		       = debug)

       -F<file>, --config-file=<file>
		       Use the given configuration file instead of the default
		       ()

       --dry-run       Don't actually do anything.

       -g, --restore-grub
		       Restores the grub menu to normal (use if a  resume  was
		       not completed sucessfully) and exits the script. A sus‐
		       pend is not performed.

       --lock-console-as <username>
		       Uses vlock to lock the entire  system  after  resuming,
		       requirng	 you  to enter the password for the given user
		       to unlock it. This overrides any username given in  the
		       configuration file. (Requires vlock)

       -n, --no-suspend
		       Disables actually suspending the system. This is useful
		       for testing the hibernate script itself.

       -r[0|1], --reboot[=<0|1>] (requires UseTuxOnIce on)
		       If 0 is specified, disables rebooting after writing the
		       image,  regardless of the Reboot option in the configu‐
		       ration file. If 1 or omitted, will force a reboot after
		       writing the image.

       --bug-report (requires UseTuxOnIce on)
		       Gathers	a  bunch of information about your machine and
		       writes it to standard output. Please attach this infor‐
		       mation along with any bug reports to the TuxOnIce mail‐
		       ing list.

EXIT CODES
       The exit codes returned by the hibernate script are currently  as  fol‐
       lows:

       0      Hibernation was completed successfully.

       2      Hibernation  was	aborted	 due  to  errors from some part of the
	      script. (eg, modules not unloading, devices  or  filesystems  in
	      use).

       3      Hibernate script was aborted by user with Ctrl+C. (This does not
	      mean the suspend was aborted by a user by pressing Escape).

       4      Hibernation was aborted by a kernel problem  (hibernate.log  and
	      dmesg should indicate why), or the user aborted the suspend with
	      the Escape key.

FILES
       /etc/hibernate/hibernate.conf
		 Contains options which influence the hibernate	 script's  be‐
		 haviour.  See hibernate.conf(5) for more information.

       /etc/hibernate/scriptlets.d/

       /usr/share/hibernate/scriptlets.d/

       /usr/local/share/hibernate/scriptlets.d/
		 These	directories  contains  "scriptlets" that provide func‐
		 tionality when suspending and resuming.  See  the  SCRIPTLET-
		 API  file  included with the distribution (which can be found
		 in /usr/share/doc/hibernate on Debian systems)	 for  informa‐
		 tion on how these work.

BUGS
       Probably lots!

       If  you	have  problems with the hibernate script or TuxOnIce, the best
       place to ask is	on  the	 mailing  list	-  tuxonice-users@lists.tuxon‐
       ice.net.	 You  will  need  to  subscribe to post. See http://www.tuxon‐
       ice.net/lists for details.

       If the suspend process itself crashes (while "Writing caches", "Reading
       caches", or "Copying original kernel back", etc), then the problem lies
       with TuxOnIce itself. See the FAQ at http://www.tuxonice.net/ for  help
       on debugging.
