Usage: mysqldump [OPTIONS] database [tables]
OR     mysqldump [OPTIONS] --databases [OPTIONS] DB1 [DB2 DB3...]
OR     mysqldump [OPTIONS] --all-databases [OPTIONS]

  -A, --all-databases   Dump all the databases. This will be same as
		        --databases with all databases selected.
  -a, --all		Include all MySQL specific create options.
  -#, --debug=...       Output debug log. Often this is 'd:t:o,filename`.
  --character-sets-dir=...
                        Directory where character sets are
  -?, --help		Display this help message and exit.
  -B, --databases       To dump several databases. Note the difference in
			usage; In this case no tables are given. All name
			arguments are regarded as databasenames.
			'USE db_name;' will be included in the output
  -c, --complete-insert Use complete insert statements.
  -C, --compress        Use compression in server/client protocol.
  --default-character-set=...
                        Set the default character set

  --delete-master-logs  Issue RESET MASTER on the master just after taking
                        the dump, and before unlocking tables.
                        This will automatically enable --first-slave.
  --master-data         This will cause the master position and filename to 
                        be appended to your output, before unlocking tables.
                        This will automatically enable --first-slave.
  -F, --flush-logs	Flush logs file in server before starting dump.
  -f, --force		Continue even if we get an sql-error.
  -h, --host=...	Connect to host.
  -l, --lock-tables     Lock all tables for read.

                        will be put in the output.
  -n, --no-create-db    'CREATE DATABASE /*!32312 IF NOT EXISTS*/ db_name;'
                        will not be put in the output. The above line will
                        be added otherwise, if --databases or
                        --all-databases option was given.
  -t, --no-create-info	Don't write table creation info.
  -d, --no-data		No row information.
  -O, --set-variable var=option
                        give a variable a value. --help lists variables
  --opt			Same as --add-drop-table --add-locks --all --quick
                        --extended-insert --lock-tables --disable-keys
  -p, --password[=...]	Password to use when connecting to server.
                        If password is not given it's solicited on the tty.

  -q, --quick		Don't buffer query, dump directly to stdout.
  -Q, --quote-names	Quote table and column names with `
  -r, --result-file=... Direct output to a given file. This option should be
                        used in MSDOS, because it prevents new line '\n'
                        from being converted to '\n\r' (newline + carriage
                        return).

  --tables              Overrides option --databases (-B).
  -T, --tab=...         Creates tab separated textfile for each table to
                        given path. (creates .sql and .txt files).
                        NOTE: This only works if mysqldump is run on
                              the same machine as the mysqld daemon.
  -u, --user=#		User for login if not current user.
