       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.

OPTIONS

   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.

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

       -i     Run in inetd server mode.

       -ii    Run in stand-alone server mode.

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

       -l     Send some messages to syslog instead of stderr to not clobber the protocol in  case
              stdout and stderr point to the same fd.  Default for inetd mode.

   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.  Otherwise, only exit codes 0 (no errors)  and
              1 (some unspecified errors) are expected.

   Modifiers:
       -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  corruption if the
              operating system crashes or the computer loses power.

       -N address
              When running in stand-alone mode with -ii bind to a

              specific interface. You can pass either a hostname or ip  address.  If  used,  this
              value must match exactly the host value in each csync2.cfg file.

       -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 directory  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.

              URLs:
                  sqlite:///some/path[/database.db3]
                  sqlite3:///some/path[/database.db3]
                  sqlite2:///some/path[/database.db]
                  mysql://[<user>:<password>@]<hostname>/[database]
                  pgsql://[<user>:<password>@]<hostname>/[database]

              If database is not given, it defaults to csync2_<qualified hostname>

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

   Creating key file:
              csync2 -k filename

   Environment variables:
              CSYNC2_SYSTEM_DIR

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

   Note:
       Csync2 will refuse to do anything if this file is found: $CSYNC2_SYSTEM_DIR/csync2.lock
