Usage: mysql [OPTIONS] [database]

  -?, --help          Display this help and exit.
  -I, --help          Synonym for -?
  --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. Disable with --disable-auto-rehash. (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.)
  --bind-address=name IP address to bind to.
  --character-sets-dir=name     Directory for character set files.
  --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.

  -#, --debug[=#]      This is a non-debug version. Catch this and exit.
  --debug-check        Check memory and open file usage at exit.
  -T, --debug-info    Print some debug info at exit.
  -D, --database=name Database to use.

  -E, --vertical      Print the output of a query (rows) vertically.
  -f, --force          Continue even if we get an SQL error.

  -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.
  -i, --ignore-spaces Ignore space after function names.
  --init-command=name SQL Command to execute when connecting to MySQL server. Will automatically be re-executed when reconnecting.
  --local-infile      Enable/disable LOAD DATA LOCAL INFILE.

  -o, --one-database  Ignore statements except those that occur while the 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 option is disabled by default.
  -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).
  --prompt=name        Set the mysql prompt to this value.
  --protocol=name      The protocol to use for connection (tcp, socket, pipe, memory).

  --ssl-key=name      X509 key in PEM format (implies --ssl).
  --ssl-crl=name      Certificate revocation list (implies --ssl).
  --ssl-crlpath=name  Certificate revocation list path (implies --ssl).
  --ssl-verify-server-cert Verify server's "Common Name" in its cert against hostname used when connecting. This option is disabled by  default.
  --ssl-mode=name      SSL connection mode.

  -t, --table          Output in table format.
  --tee=name          Append everything into outfile. See interactive help (\h) also. Does not work in batch mode. Disable with --disable-tee. This option is disabled by default.
  -u, --user=name      User for login if not current user.

  -U, --i-am-a-dummy  Synonym for option --safe-updates, -U.
  -v, --verbose        Write more. (-v -v -v gives the table output format).
  -V, --version        Output version information and exit.

  -w, --wait          Wait and retry if connection is down.
  --connect-timeout=# Number of seconds before connection timeout.
  --max-allowed-packet=# The maximum packet length to send to or receive from server.

  --select-limit=#    Automatic limit for SELECT when using --safe-updates.
  --max-join-size=#    Automatic limit for rows in a join when using --safe-updates.

  --secure-auth        Refuse client connecting to server if it uses old  (pre-4.1.1) protocol.  (Defaults to on; use --skip-secure-auth to disable.)
  --server-arg=name   Send embedded server this as a parameter.
  --show-warnings     Show warnings after every statement.
  --plugin-dir=name   Directory for client-side plugins.
  --default-auth=name    Default authentication client-side plugin to use.

  --histignore=name     A colon-separated list of patterns to keep statements from getting logged into mysql history.
  --binary-mode        By default, ASCII '\0' is disallowed and '\r\n' is  translated to '\n'. This switch turns off both features, and also turns off parsing of all client commands except \C and DELIMITER, in non-interactive mode (for input piped to mysql or loaded using the 'source' command). This is necessary when processing output from mysqlbinlog  that may contain blobs.
  --server-public-key-path=name  File path to the server public RSA key in PEM format.
  --connect-expired-password  Notify the server that this client is prepared to handle expired password sandbox mode.
