/usr/bin/mariadb-embedded

/usr/bin/mariadb-embedded from 12.3.3-MariaDB, client 15.2 for Linux (x86_64) using readline 5.1
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

Usage: /usr/bin/mariadb-embedded [OPTIONS] [database]

Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf ~/.my.cnf
The following groups are read: mysql mariadb-client client client-server client-mariadb
The following options may be given as the first argument:
--print-defaults          Print the program argument list and exit.
--no-defaults             Don't read default options from any option file.
The following specify which files/extra groups are read (specified before remaining options):
--defaults-file=#         Only read default options from the given file #.
--defaults-extra-file=#   Read this file after the global files are read.
--defaults-group-suffix=# Additionally read default groups with # appended as a suffix.

  -?, --help          Display this help and exit.
  -I, --help          Synonym for -?
  --abort-source-on-error
                      Abort 'source filename' operations in case of errors
  --auto-rehash       Enable automatic rehashing. One doesn't need to use
                      'rehash' to get table and field completion, but startup
                      and reconnecting may take a longer time.
                      (Defaults to on; use --skip-auto-rehash to disable.)
  -A, --no-auto-rehash
                      No automatic rehashing. One has to use 'rehash' to get
                      table and field completion. This gives a quicker start of
                      mysql and disables rehashing on reconnect.
  --auto-vertical-output
                      Automatically switch to vertical output mode if the
                      result is wider than the terminal width.
  -B, --batch         Don't use history file. Disable interactive behavior.
                      (Enables --silent.)
  --binary-as-hex     Print binary data as hex
  --binary-mode       Binary mode allows certain character sequences to be
                      processed as data that would otherwise be treated with a
                      special meaning by the parser. Specifically, this switch
                      turns off parsing of all client commands except \C and
                      DELIMITER in non-interactive mode (i.e., when binary mode
                      is combined with either 1) piped input, 2) the --batch
                      mysql option, or 3) the 'source' command). Also, in
                      binary mode, occurrences of '\r\n' and ASCII '\0' are
                      preserved within strings, whereas by default, '\r\n' is
                      translated to '\n' and '\0' is disallowed in user input.
  --character-sets-dir=name
                      Directory for character set files.
  --column-names      Write column names in results.
                      (Defaults to on; use --skip-column-names to disable.)
  -N, --skip-column-names
                      Don't write column names in results.
  --column-type-info  Display column type information.
  -c, --comments      Preserve comments. Send comments to the server. The
                      default is --skip-comments (discard comments), enable
                      with --comments.
  -C, --compress      Use compression in server/client protocol.
  --connect-expired-password
                      Notify the server that this client is prepared to handle
                      expired password sandbox mode even if --batch was
                      specified.
  --connect-timeout=# Number of seconds before connection timeout.
  -D, --database=name Database to use.
  -#, --debug[=#]     This is a non-debug version. Catch this and exit.

  --enable-cleartext-plugin
                      Obsolete option. Exists only for MySQL compatibility.
  -e, --execute=name  Execute command and quit. (Disables --force and history
                      file.)
  -f, --force         Continue even if we get an SQL error. Sets
                      abort-source-on-error to 0
  -h, --host=name     Connect to host. Defaults in the following order:
                      $MARIADB_HOST, $MYSQL_HOST, and then localhost
  -H, --html          Produce HTML output.
  -i, --ignore-spaces Ignore space after function names.
  --init-command=name SQL Command to execute when connecting to MariaDB server.
                      Will automatically be re-executed when reconnecting.
  --line-numbers      Write line numbers for errors.
                      (Defaults to on; use --skip-line-numbers to disable.)
  -L, --skip-line-numbers
                      Don't write line number for errors.
  --local-infile      Enable LOAD DATA LOCAL INFILE.

                      --safe-updates.
  -G, --named-commands
                      Enable named commands. Named commands mean this program's
                      internal commands; see mysql> help . When enabled, the
                      named commands can be used from any line of the query,
                      otherwise only from the first line, before an enter.
                      Disable with --disable-named-commands. This option is
                      disabled by default.
  --net-buffer-length=#
                      The buffer size for TCP/IP and socket communication.
  -b, --no-beep       Turn off beep on error.

                      default database is the one named at the command line.
  --pager[=name]      Pager to use to display results. If you don't supply an
                      option, the default pager is taken from your ENV variable
                      PAGER. Valid pagers are less, more, cat [> filename],
                      etc. See interactive help (\h) also. This option does not
                      work in batch mode. Disable with --disable-pager. This

  -p, --password[=name]
                      Password to use when connecting to server. If password is
                      not given it's asked from the tty.

  -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).
  --print-query-on-error
                      Print the query if there was an error. Is only enabled in
                      --batch mode if verbose is not set (as then the query
                      would be printed anyway)
                      (Defaults to on; use --skip-print-query-on-error to disable.)
  --progress-reports  Get progress reports for long running commands (like
                      ALTER TABLE)
                      (Defaults to on; use --skip-progress-reports to disable.)
  --prompt=name       Set the command line prompt to this value.
  --protocol=name     The protocol to use for connection (tcp, socket, pipe).
  -q, --quick         Don't cache result, print it row by row. This may slow
                      down the server if the output is suspended. Doesn't use
                      history file.
  --quick-max-column-width=#

  -U, --i-am-a-dummy  Synonym for option --safe-updates, -U.
  --sandbox           Disallow commands that access the file system (except \P
                      without an argument and \e).
  --script-dir=name   Set an alternative directory path for searching scripts
                      invoked via the source command.
  --secure-auth       Refuse client connecting to server if it uses old
