Linux "mysqlshow" Command Line Options and Examples

display database, table, and column information

The mysqlshow client can be used to quickly see which databases exist, their tables, or a table's columns or indexes. mysqlshow provides a command-line interface to several SQL SHOW statements. See Section 13.

Usage:

mysqlshow [options] [db_name [tbl_name [col_name]]]

Command Line Options:

--help

Display a help message and exit.


                            mysqlshow --help ...

--bind-address

On a computer having multiple network interfaces, use this option to select which interface to use for connecting to the MySQLserver.


                            mysqlshow --bind-address ...

--character-sets-dir

The directory where character sets are installed. See Section 10.15, “Character Set Configuration”.


                            mysqlshow --character-sets-dir ...

--compress

Compress all information sent between the client and the server if possible. See Section 4.2.6, “Connection Compression Control”.As of MySQL 8.0.18, this option is deprecated. It will be removed in a future MySQL version. See the section called “LegacyConnection Compression Configuration”.


                            mysqlshow --compress ...

--count

Show the number of rows per table. This can be slow for non-MyISAM tables.


                            mysqlshow --count ...

--debug[

Write a debugging log. A typical debug_options string is d:t:o,file_name. The default is d:t:o.


                            mysqlshow --debug[ ...

--debug-check

Print some debugging information when the program exits.


                            mysqlshow --debug-check ...

--debug-info

Print debugging information and memory and CPU usage statistics when the program exits.


                            mysqlshow --debug-info ...

--default-character-set

Use charset_name as the default character set. See Section 10.15, “Character Set Configuration”.


                            mysqlshow --default-character-set ...

--default-auth

A hint about which client-side authentication plugin to use. See Section 6.2.17, “Pluggable Authentication”.


                            mysqlshow --default-auth ...

--defaults-extra-file

Read this option file after the global option file but (on Unix) before the user option file. If the file does not exist or isotherwise inaccessible, an error occurs. file_name is interpreted relative to the current directory if given as a relative pathname rather than a full path name.For additional information about this and other option-file options, see Section 4.2.2.3, “Command-Line Options that AffectOption-File Handling”.


                            mysqlshow --defaults-extra-file ...

--defaults-file

Use only the given option file. If the file does not exist or is otherwise inaccessible, an error occurs. file_name isinterpreted relative to the current directory if given as a relative path name rather than a full path name.Exception: Even with --defaults-file, client programs read .mylogin.cnf.For additional information about this and other option-file options, see Section 4.2.2.3, “Command-Line Options that AffectOption-File Handling”.


                            mysqlshow --defaults-file ...

--defaults-group-suffix

Read not only the usual option groups, but also groups with the usual names and a suffix of str. For example, mysqlshow normallyreads the [client] and [mysqlshow] groups. If the --defaults-group-suffix=_other option is given, mysqlshow also reads the[client_other] and [mysqlshow_other] groups.For additional information about this and other option-file options, see Section 4.2.2.3, “Command-Line Options that AffectOption-File Handling”.


                            mysqlshow --defaults-group-suffix ...

--enable-cleartext-plugin

Enable the mysql_clear_password cleartext authentication plugin. (See Section 6.4.1.4, “Client-Side Cleartext PluggableAuthentication”.)


                            mysqlshow --enable-cleartext-plugin ...

--get-server-public-key

Request from the server the RSA public key that it uses for key pair-based password exchange. This option applies to clients thatconnect to the server using an account that authenticates with the caching_sha2_password authentication plugin. For connectionsby such accounts, the server does not send the public key to the client unless requested. The option is ignored for accounts thatdo not authenticate with that plugin. It is also ignored if RSA-based password exchange is not needed, as is the case when theclient connects to the server using a secure connection.If --server-public-key-path=file_name is given and specifies a valid public key file, it takes precedence over


                            mysqlshow --get-server-public-key ...

--get-server-public-key.

For information about the caching_sha2_password plugin, see Section 6.4.1.3, “Caching SHA-2 Pluggable Authentication”.


                            mysqlshow --get-server-public-key. ...

--host

Connect to the MySQL server on the given host.


                            mysqlshow --host ...

--keys

Show table indexes.


                            mysqlshow --keys ...

--login-path

Read options from the named login path in the .mylogin.cnf login path file. A “login path” is an option group containing optionsthat specify which MySQL server to connect to and which account to authenticate as. To create or modify a login path file, usethe mysql_config_editor utility. See mysql_config_editor(1).For additional information about this and other option-file options, see Section 4.2.2.3, “Command-Line Options that AffectOption-File Handling”.


                            mysqlshow --login-path ...

--no-defaults

Do not read any option files. If program startup fails due to reading unknown options from an option file, --no-defaults can beused to prevent them from being read.The exception is that the .mylogin.cnf file, if it exists, is read in all cases. This permits passwords to be specified in asafer way than on the command line even when --no-defaults is used. (.mylogin.cnf is created by the mysql_config_editor utility.See mysql_config_editor(1).)For additional information about this and other option-file options, see Section 4.2.2.3, “Command-Line Options that AffectOption-File Handling”.


                            mysqlshow --no-defaults ...

--password[

The password of the MySQL account used for connecting to the server. The password value is optional. If not given, mysqlshowprompts for one. If given, there must be no space between --password= or -p and the password following it. If no password optionis specified, the default is to send no password.Specifying a password on the command line should be considered insecure. To avoid giving the password on the command line, use anoption file. See Section 6.1.2.1, “End-User Guidelines for Password Security”.To explicitly specify that there is no password and that mysqlshow should not prompt for one, use the --skip-password option.


                            mysqlshow --password[ ...

--pipe

On Windows, connect to the server using a named pipe. This option applies only if the server was started with the named_pipesystem variable enabled to support named-pipe connections. In addition, the user making the connection must be a member of theWindows group specified by the named_pipe_full_access_group system variable.


                            mysqlshow --pipe ...

--plugin-dir

The directory in which to look for plugins. Specify this option if the --default-auth option is used to specify an authenticationplugin but mysqlshow does not find it. See Section 6.2.17, “Pluggable Authentication”.


                            mysqlshow --plugin-dir ...

--port

For TCP/IP connections, the port number to use.


                            mysqlshow --port ...

--print-defaults

Print the program name and all options that it gets from option files.For additional information about this and other option-file options, see Section 4.2.2.3, “Command-Line Options that AffectOption-File Handling”.


                            mysqlshow --print-defaults ...

--protocol

The connection protocol to use for connecting to the server. It is useful when the other connection parameters normally result inuse of a protocol other than the one you want. For details on the permissible values, see Section 4.2.4, “Connecting to the MySQLServer Using Command Options”.


                            mysqlshow --protocol ...

--secure-auth

This option was removed in MySQL 8.0.3.


                            mysqlshow --secure-auth ...

--server-public-key-path

The path name to a file containing a client-side copy of the public key required by the server for RSA key pair-based passwordexchange. The file must be in PEM format. This option applies to clients that authenticate with the sha256_password orcaching_sha2_password authentication plugin. This option is ignored for accounts that do not authenticate with one of thoseplugins. It is also ignored if RSA-based password exchange is not used, as is the case when the client connects to the serverusing a secure connection.If --server-public-key-path=file_name is given and specifies a valid public key file, it takes precedence over


                            mysqlshow --server-public-key-path ...

--shared-memory-base-name

On Windows, the shared-memory name to use for connections made using shared memory to a local server. The default value is MYSQL.The shared-memory name is case-sensitive.This option applies only if the server was started with the shared_memory system variable enabled to support shared-memoryconnections.


                            mysqlshow --shared-memory-base-name ...

--show-table-type

Show a column indicating the table type, as in SHOW FULL TABLES. The type is BASE TABLE or VIEW.


                            mysqlshow --show-table-type ...

--socket

For connections to localhost, the Unix socket file to use, or, on Windows, the name of the named pipe to use.On Windows, this option applies only if the server was started with the named_pipe system variable enabled to support named-pipeconnections. In addition, the user making the connection must be a member of the Windows group specified by thenamed_pipe_full_access_group system variable.


                            mysqlshow --socket ...

--ssl*

Options that begin with --ssl specify whether to connect to the server using SSL and indicate where to find SSL keys andcertificates. See the section called “Command Options for Encrypted Connections”.


                            mysqlshow --ssl* ...

--status

Display extra information about each table.


                            mysqlshow --status ...

--tls-ciphersuites

The permissible ciphersuites for encrypted connections that use TLSv1.3. The value is a list of one or more colon-separatedciphersuite names. The ciphersuites that can be named for this option depend on the SSL library used to compile MySQL. Fordetails, see Section 6.3.2, “Encrypted Connection TLS Protocols and Ciphers”.This option was added in MySQL 8.0.16.


                            mysqlshow --tls-ciphersuites ...

--tls-version

The permissible TLS protocols for encrypted connections. The value is a list of one or more comma-separated protocol names.
