Dumps a MySQL binary log in a format usable for viewing or for piping to
the mysql command line client

Usage: mysqlbinlog [options] log-files
--character-sets-dir=name
                      Directory where character sets are.
-d, --database=name List entries for just this database (local log only). ---误操作可以对单个库进行恢复
-D, --disable-log-bin
                      Disable binary log. This is useful, if you enabled
                      --to-last-log and are sending the output to the same
                      MySQL server. This way you could avoid an endless loop.
                      You would also like to use it when restoring after a
                      crash to avoid duplication of the statements you already
                      have. NOTE: you will need a SUPER privilege to use this
                      option.
-f, --force-read    Force reading unknown binlog events.
-?, --help          Display this help and exit.
-H, --hexdump       Augment output with hexadecimal and ASCII event dump.
-h, --host=name     Get the binlog from server.
-o, --offset=#      Skip the first N entries.
-p, --password[=name]
                      Password to connect to remote server.
-P, --port=#        Port number to use for connection or 0 for default to, in
                      order of preference, my.cnf, $MYSQL_TCP_PORT,
                      /etc/services, built-in default (3306).
-j, --position=#    Deprecated. Use --start-position instead.
--protocol=name     The protocol of connection (tcp,socket,pipe,memory).
-r, --result-file=name
                      Direct output to a given file.
-R, --read-from-remote-server
                      Read binary logs from a MySQL server
--open_files_limit=#
                      Used to reserve file descriptors for usage by this
                      program
--set-charset=name Add 'SET NAMES character_set' to the output.
-s, --short-form    Just show the queries, no extra info.
-S, --socket=name   Socket file to use for connection.
--start-datetime=name
                      Start reading the binlog at first event having a datetime
                      equal or posterior to the argument; the argument must be
                      a date and time in the local time zone, in any format
                      accepted by the MySQL server for DATETIME and TIMESTAMP
                      types, for example: 2004-12-25 11:25:56 (you should
                      probably use quotes for your shell to set it properly).
--stop-datetime=name
                      Stop reading the binlog at first event having a datetime
                      equal or posterior to the argument; the argument must be
                      a date and time in the local time zone, in any format
                      accepted by the MySQL server for DATETIME and TIMESTAMP
                      types, for example: 2004-12-25 11:25:56 (you should
                      probably use quotes for your shell to set it properly).
--start-position=# Start reading the binlog at position N. Applies to the
                      first binlog passed on the command line.
--stop-position=#   Stop reading the binlog at position N. Applies to the
                      last binlog passed on the command line.
-t, --to-last-log   Requires -R. Will not stop at the end of the requested
                      binlog but rather continue printing until the end of the
                      last binlog of the MySQL server. If you send the output
                      to the same MySQL server, that may lead to an endless
                      loop.
-u, --user=name     Connect to the remote server as username.
-l, --local-load=name
                      Prepare local temporary files for LOAD DATA INFILE in the
                      specified directory.
-V, --version       Print version and exit.
