       csync2 is distributed under the GNU public license.  See	the file COPY-

       This manual page	documents briefly the csync2 command.
       A verbose manual	can be found on	the csync2 homepage:

       csync2 is a program for cluster wide file synchronization.

   With	file parameters:
       -h [-r] file..
	      Add (recursive) hints for	check to db

       -c [-r] file..
	      Check files and maybe add	to dirty db

       -u [-d] [-r] file..
	      Updates files if listed in dirty db

       -o [-r] file..
	      Create list of files in compare-mode

       -f [-r] file..
	      Force files to win next conflict resolution

       -m file..
	      Mark files in database as	dirty

   Simple mode:
       -x [-d] [[-r] file..]
	      Run checks for all given files and update	remote hosts.

   Without file	parameters:
       -c     Check all	hints in db and	eventually mark	files as dirty

       -u [-d] Update (transfer	dirty files to peers and mark as clear)

       -H     List all pending hints from status db

       -L     List all file-entries from status	db

       -M     List all dirty files from	status db

       -S myname peername
	      List file-entries	from status db for this	synchronization	pair.

       -T     Test if everything is in sync with all peers.

       -T filename
	      Test if this file	is in sync with	all peers.

       -T myname peername
	      Test if this synchronization pair	is in sync.

       -T myname peer file
	      Test only	this file in this sync pair.

       -TT    As -T, but print the unified diffs.

	      The modes	-H, -L,	-M and -S return 2  if	the  requested	db  is
	      empty.  The mode -T returns 2 if both hosts are in sync.

       -i     Run in inetd server mode.

       -ii    Run in stand-alone server	mode.

       -iii   Run in stand-alone server	mode (one connect only).

       -R     Remove files from	database which do not match config entries.

   Exit	codes:
	      The  modes  -H,  -L,  -M	and -S return 2	if the requested db is
	      empty.  The mode -T returns 2 if both hosts are in sync.	Other-
	      wise,  only exit codes 0 (no errors) and 1 (some unspecified er-
	      rrors) are expected.

       -r     Recursive	operation over subdirectories

       -d     Dry-run on all remote update operations

       -B     Do not block everything into big SQL  transactions.  This	 slows
	      down  csync2  but	allows multiple	csync2 processes to access the
	      database at the same time. Use e.g. when slow lines are used  or
	      huge files are transferred.

       -A     Open database in asynchronous mode. This will cause data corrup-
	      tion if the operating  system  crashes  or  the  computer	 loses

       -I     Init-run.	 Use  with care	and read the documentation first!  You
	      usually do not need this	option	unless	you  are  initializing
	      groups with really large file lists.

       -X     Also add removals	to dirty db when doing a -TI run.

       -U     Don't mark all other peers as dirty when doing a -TI run.

       -G Group1,Group2,Group3,...

	      Only use these groups from config-file.

       -P peer1,peer1,...

	      Only  update  these  peers (still	mark all as dirty).  Only show
	      files for	these peers in -o (compare) mode.

       -F     Add new entries to dirty database	with force flag	set.

       -t     Print timestamps to debug	output (e.g. for profiling).

       -s filename

	      Print timestamps also to this file.

       -W fd  Write a list of directories in which relevant files can be found
	      to the specified file descriptor (when doing a -c	run).  The di-
	      rectory names in this output are zero-terminated.

   Database switches:
       -D database-dir or url

	      default: /var/lib/csync2
		  Absolute path: use sqlite database in	that directory.


	      If database is not given,	it defaults to csync2_<qualified host-

	      Note   that  for	non-sqlite  backends,  the  database  name  is
	      "cleaned", characters outside of	[0-9][a-z][A-Z]	 will  be  re-
	      placed with _.

   Creating key	file:
	      csync2 -k	filename

   Environment variables:

	      Directory	 containing  csync2.cfg	and other csync2 system	files.
	      Defaults to /etc.

       Csync2 will refuse to do	anything if this file is  found:  $CSYNC2_SYS-
