Marks the end of the list of mysqlsh options and the start of a command and its arguments for MySQL Shell's API command line integration. You can execute methods of the MySQL Shell global objects from the command line using this syntax:

mysqlsh [options]  -- object method [arguments]

See Section 5.8, “API Command Line Integration” for more information.

Authentication method to use for the account. Depends on the authentication plugin used for the account's password. For MySQL Shell connections using classic MySQL protocol, specify the name of the authentication plugin, for example caching_sha2_password. For MySQL Shell connections using X Protocol, specify one of the following options:

AUTO

FALLBACK

FROM_CAPABILITIES

MYSQL41

PLAIN

SHA256_MEMORY

For MySQL Shell connections using classic MySQL protocol, specify the name of the authentication plugin used by the user account, for example caching_sha2_password (which is the default for user accounts created in MySQL 8.0). MySQL Shell uses the MySQL client library for client-side authentication for these connections. The following authentication methods require additional configuration:

clear_text_password

authentication_ldap_sasl_client

authentication_kerberos_client

Cached ticket-granting tickets (TGTs) for Kerberos authentication are supported from MySQL 8.0.27 when the --auth-method option is used to specify the authentication_ldap_sasl_client or authentication_kerberos_client plugin, and the --mysql-plugin-dir option is used to provide a path to the plugin. To use cached TGTs, do not specify a user and password in the connection options. When you specify one of these plugins and do not specify a user and password, MySQL Shell does not supply the system user name, does not prompt for a password, and does not attempt to use the Secret Store helper to retrieve or store credentials.

For more information, see Section 4.3.5, “Using LDAP and Kerberos Authentication”.

Ensures that the target server is part of an InnoDB Cluster and if so, sets the cluster global variable to the cluster object.

In SQL mode, before printing the returned result set for a query, print metadata for each column in the result set, such as the column type and collation.

The column type is returned as both the type used by MySQL Shell (Type), and the type used by the original database (DBType). For MySQL Shell connections using classic MySQL protocol, DBType is as returned by the protocol, and for X Protocol connections, DBType is inferred from the available information. The column length (Length) is returned in bytes.

Controls compression of information sent between the client and the server using this connection. In MySQL Shell 8.0.14 through 8.0.19 this option is available for classic MySQL protocol connections only, and does not use the options required, preferred, and disabled. In those releases, when you specify --compress, compression is activated if possible. From MySQL Shell 8.0.20 it is also available for X Protocol connections, and you can optionally specify required, preferred, or disabled. When just --compress is specified from MySQL Shell 8.0.20, the meaning is --compress=required. See Section 4.3.7, “Using Compressed Connections” for information on using MySQL Shell's compression control in all releases.

Configures how long MySQL Shell waits (in milliseconds) to establish a global session specified through command-line arguments.

The Secret Store Helper that is to be used to store and retrieve passwords. See Section 4.4, “Pluggable Password Store”.

The default schema to use. This is an alias for --schema.

Enable X Plugin on connection with a MySQL 5.7 server, so that you can use X Protocol connections for subsequent connections. Requires a connection using classic MySQL protocol. Not relevant for MySQL 8.0 servers, which have X Plugin enabled by default.

Log SQL statements that are executed by AdminAPI operations (excluding sandbox operations). By default, this category of statement is not written to the MySQL Shell application log file or sent to the console as verbose output, even when the --log-level and --verbose options are set. The value of the option is an integer in the range from 0 to 2. 0 does not log or display this category of statement, which is the default behavior if you do not specify the option. 1 logs SQL statements that are executed by AdminAPI operations, with the exceptions of SELECT statements and SHOW statements (this is the default setting if you specify the option on the command line without a value). 2 logs SQL statements that are executed by regular AdminAPI operations in full, including SELECT and SHOW statements. See Chapter 12, MySQL Shell Logging and Debug for more information.

Log all SQL statements executed by MySQL Shell to the MySQL Shell log file, mysqlsh.log

The following options are available:

off

error

on

all

unfiltered

Deprecated in version 8.0.13 of MySQL Shell. Use --password[=password] instead.

Deprecated in version 8.0.13 of MySQL Shell. Use --user=user_name instead.

Execute the command using the currently active language and quit. This option is mutually exclusive with the --file=file_name option.

The factor or factors for which FIDO device registration must be performed. This option value must be a single value, or two values separated by commas. Each value must be 2 or 3, so the permitted option values are '2', '3', '2,3' and '3,2'. For example:

mysqlsh --user=user_name --password1 --fido-register-factor=2
Enter password: (enter factor 1 password)

To register an account for passwordless authentication, with the FIDO device being the only authentication, you use --fido-register-factor=2 to provide the temporary password. The server moves FIDO authentication to the first factor after registration succeeds.

Specify a file to process in Batch mode. Any options specified after this are used as arguments of the processed file.

Continue processing in SQL and Batch modes even if errors occur.

Specify strings that are not added to the MySQL Shell history. Strings are separated by a colon. Matching is case insensitive, and the wildcards * and ? can be used. The default ignored strings are specified as “*IDENTIFIED*:*PASSWORD*”. See Section 5.5, “Code History”.

Connect to the MySQL server on the given host. On Windows, if you specify --host=. or -h . (giving the host name as a period), MySQL Shell connects using the default named pipe (which has the name MySQL), or an alternative named pipe that you specify using the --socket option.

MySQL Shell equivalent of --get-server-public-key.

If --server-public-key-path=file_name is given and specifies a valid public key file, it takes precedence over --get-server-public-key.

Import JSON documents from a file or standard input to a MySQL Server collection or relational table, using the JSON import utility. For instructions, see Section 11.2, “JSON Import Utility”.

Emulate Interactive mode in Batch mode.

Start in JavaScript mode.

Controls JSON wrapping for MySQL Shell output from this session. This option is intended for interfacing MySQL Shell with other programs, for example as part of testing. For changing query results output to use the JSON format, see --result-format.

When the --json option has no value or a value of pretty, the output is generated as pretty-printed JSON. With a value of raw, the output is generated in raw JSON format. In any of these cases, the --result-format option and its aliases and the value of the resultFormat MySQL Shell configuration option are ignored. With a value of off, JSON wrapping does not take place, and result sets are output as normal in the format specified by the --result-format option or the resultFormat configuration option.

Change the location of the MySQL Shell application log file mysqlsh.log for this MySQL Shell instance. The default location for the application log file is the user configuration path, which defaults to %APPDATA%\MySQL\mysqlsh\ on Windows or ~/.mysqlsh/ on Unix. You can override the user configuration path for all MySQL Shell instances by defining the environment variable MYSQLSH_USER_CONFIG_HOME. The --log-file option applies to the individual MySQL Shell instance, meaning that different instances can write to different locations.

Change the logging level for the MySQL Shell application log file mysqlsh.log, or disable logging to the file. The option requires a value, which can be either an integer in the range from 1 to 8, or one of none, internal, error, warning, info, debug, debug2, or debug3. Specifying 1 or none disables logging to the application log file. Level 5 (info) is the default if you do not specify this option. See Chapter 12, MySQL Shell Logging and Debug.

Deprecated in version 8.0.13 of MySQL Shell. Automatically attempts to use X Protocol to create the session's connection, and falls back to classic MySQL protocol if X Protocol is unavailable.

Sets the global session created at start up to use a classic MySQL protocol connection. The --mc option with two hyphens replaces the previous single hyphen -mc option from MySQL Shell 8.0.13.

Sets a non-persistent path to the client-side authentication plugins by overriding the value of the shell.options.mysqlPluginDir setting. Client-side plugins are shipped in the MySQL Server packages and can be located relative to the MySQL base directory (the value of the basedir system variable). For example:

For a list of the client authentication plugins that ship with the server, see Available Authentication Plugins[5].

Sets the global session created at start up to use an X Protocol connection. The --mx option with two hyphens replaces the previous single hyphen -mx option from MySQL Shell 8.0.13.

Enable automatic loading of table names based on the active default schema.

Disable loading of table names for autocompletion based on the active default schema and the DevAPI db object. Use \rehash to reload the name information manually.

When connecting to the server, if the user has a passwordless account, which is insecure and not recommended, or if socket peer-credential authentication is in use (for Unix socket connections), you must use --no-password to explicitly specify that no password is provided and the password prompt is not required.

Disables the interactive wizards provided by operations such as creating connections, dba.configureInstance(), Cluster.rebootClusterFromCompleteOutage() and so on. Use this option when you want to script MySQL Shell and not have the interactive prompts displayed. For more information see Section 5.6, “Batch Code Execution” and Section 5.8, “API Command Line Integration”.

The external pager tool used by MySQL Shell to display text output for statements executed in SQL mode and other selected commands such as online help. If you do not set a pager, the pager specified by the PAGER environment variable is used. See Section 4.6, “Using a Pager”.

Read the password from standard input, rather than from the terminal. This option does not affect any other password behaviors, such as the password prompt.

The password to use when connecting to the server. The maximum password length that is accepted for connecting to MySQL Shell is 128 characters.

--password1, --password2 and --password3 are the passwords to use for accounts that require multifactor authentication. You can supply up to three passwords. The options work in the same way as the --password option, and --password1 is treated as equivalent to that option. You can specify a password value following the option on the command line (which is insecure), or if the options are given without a password value, MySQL Shell prompts the user for each password in turn. These options are available from MySQL Shell 8.0.28, where they are only supported for classic MySQL protocol connections made using command-line arguments.

The password for the second authentication method for accounts that require multifactor authentication. See the description for the --password1 option.

The password for the third authentication method for accounts that require multifactor authentication. See the description for the --password1 option.

The TCP/IP port number to use for the connection. The default is port 33060.

Start in Python mode.

Execute a Python command and quit. Any options specified after this are treated as arguments of the processed command.

Execute the specified Python module as a script in MySQL Shell's Python mode. --pym works in the same way as Python's -m command line option. This option is available from MySQL Shell 8.0.22.

Start without printing introductory information. MySQL Shell normally prints information about the product, information about the session (such as the default schema and connection ID), warning messages, and any errors that are returned during startup and connection. When you specify --quiet-start with no value or a value of 1, information about the MySQL Shell product is not printed, but session information, warnings, and errors are printed. With a value of 2, only errors are printed.

Drop and recreate the schema that was specified in the connection options, either as part of a URI-like connection string or using the --schema, --database, or -D option. The schema is deleted if it exists.

Ensures that the target server is part of an InnoDB Cluster or InnoDB ReplicaSet and if it is not the primary, finds the primary and connects to it. MySQL Shell exits with an error if any of the following is true when using this option:

Ensures that the target server belongs to an InnoDB ReplicaSet, and if so, populates the rs global variable with the InnoDB ReplicaSet. You can then administer the InnoDB ReplicaSet using the rs global variable, for example by issuing rs.status().

Ensures that the target server is part of a single-primary InnoDB Cluster or InnoDB ReplicaSet and if it is not a secondary, finds a secondary and connects to it. MySQL Shell exits with an error if any of the following is true when using this option:

Set the value of the resultFormat MySQL Shell configuration option for this session. Formats are as follows:

table

tabbed

vertical

json or json/pretty

ndjson or json/raw

json/array

If the --json command line option is used to activate JSON wrapping for output for the session, the --result-format option and its aliases and the value of the resultFormat configuration option are ignored.

Controls whether passwords are automatically stored in the secret store. always means passwords are always stored unless they are already in the store or the server URL is excluded by a filter. never means passwords are never stored. prompt, which is the default, means users are asked whether to store the password or not. See Section 4.4, “Pluggable Password Store”.

The default schema to use.

MySQL Shell equivalent of --server-public-key-path.

If --server-public-key-path=file_name is given and specifies a valid public key file, it takes precedence over --get-server-public-key.

When true is specified, which is the default, in SQL mode, MySQL Shell displays warnings after each SQL statement if there are any. If false is specified, warning are not displayed.

On Unix, when a path is specified, the path is the name of the Unix socket file to use for the connection. If you specify --socket with no value and no equal sign, or -S without a value, the default Unix socket file for the appropriate protocol is used.

On Windows, the path is the name of the named pipe to use for the connection. The pipe name is not case-sensitive. On Windows, you must specify a path, and the --socket option is available for classic MySQL protocol sessions only.

You cannot specify a socket if you specify a port or a host name other than localhost on Unix or a period (.) on Windows.

Start in SQL mode, auto-detecting the protocol to use if it is not specified as part of the connection information. When the protocol to use is not specified, defaults to an X Protocol connection, falling back to a classic MySQL protocol connection. To force a connection to use a specific protocol see the --sqlx or --sqlc options. Alternatively, specify a protocol to use as part of a URI-like connection string or use the --port option. See Section 4.3, “MySQL Shell Connections” and MySQL Shell Ports[7]. for more information.

Start in SQL mode forcing the connection to use classic MySQL protocol, for example to use MySQL Shell with a server that does not support X Protocol. If you do not specify the port as part of the connection, when you provide this option MySQL Shell uses the default classic MySQL protocol port which is usually 3306. The port you are connecting to must support classic MySQL protocol, so for example if the connection you specify uses the X Protocol default port 33060, the connection fails with an error. See Section 4.3, “MySQL Shell Connections” and MySQL Shell Ports[7]. for more information.

Start in SQL mode forcing the connection to use X Protocol. If you do not specify the port as part of the connection, when you provide this option MySQL Shell uses the default X Protocol port which is usually 33060. The port you are connecting to must support X Protocol, so for example if the connection you specify uses the classic MySQL protocol default port 3306, the connection fails with an error. See Section 4.3, “MySQL Shell Connections” and MySQL Shell Ports[7]. for more information.

Create an SSH tunnel that provides an encrypted connection to the MySQL server instance. Supply the URI for connection to the SSH server in the format [user@]host[:port], for example:

--ssh root@198.51.100.4:2222

When you use this option, you must also specify the --user, --host, and --port options, or a URI, for connection to the MySQL server instance. For information on SSH tunnel connections from MySQL Shell, see Section 4.3.6, “Using an SSH Tunnel”.

Specify the path to an SSH configuration file for the connection to the SSH server. You can use the MySQL Shell configuration option ssh.configFile to set a custom file as the default if this option is not specified. If ssh.configFile has not been set, the default is the standard SSH configuration file ~/.ssh/config. If you specify --ssh-config-file with an empty value, the default file specified by ssh.configFile is ignored, and the ~/.ssh/config file is used instead.

Specify the path to an identity file for the connection to the SSH server. The default if this option is not specified is the standard private key file in the SSH configuration folder (~/.ssh/id_rsa).

Options that begin with --ssl specify whether to connect to the server using SSL and indicate where to find SSL keys and certificates. The mysqlsh SSL options function in the same way as the SSL options for MySQL Server, see Command Options for Encrypted Connections[8] for more information.

mysqlsh accepts these SSL options: --ssl-mode, --ssl-ca, --ssl-capath, --ssl-cert, --ssl-cipher, --ssl-crl, --ssl-crlpath, --ssl-key, --tls-version.

Send SQL statements that you issue in MySQL Shell’s SQL mode to the operating system’s system logging facility (syslog on Unix, or the Windows Event Log). System logging for SQL statements only takes place when MySQL Shell is started in interactive mode, so either a normal start or a start with the --interactive option. It does not take place if the --execute or --file options are used at startup to run mysqlsh in batch mode. See Section 12.3, “System Logging for User SQL Statements” for more information.

Display results in tab separated format in interactive mode. The default for that mode is table format. This option is an alias of the --result-format=tabbed option.

Display results in table format in batch mode. The default for that mode is tab separated format. This option is an alias of the --result-format=table option.

Create a connection upon startup, specifying the connection options in a URI-like string as described at Connecting to the Server Using URI-Like Strings or Key-Value Pairs[9].

The MySQL user name to use when connecting to the server.

Activate verbose output to the console and specify the level of detail. The value is an integer in the range from 0 to 4. 0 displays no messages, which is the default verbosity setting when you do not specify the option. 1 displays error, warning and informational messages (this is the default setting if you specify the option on the command line without a value). 2, 3, and 4 add higher levels of debug messages. See Chapter 12, MySQL Shell Logging and Debug for more information.

Display the version of MySQL Shell and exit.

Display results vertically, as when the \G terminator is used for an SQL query. This option is an alias of the --result-format=vertical option.
