CHAPTER 27 • THE MANY MYSQL CLIENTSwww.it-ebooks.info• --port=port_num, -P: Specifies the port to use when connecting to the MySQL server.Note that you can’t just specify a nonstandard port (3306 is the default) withoutconfiguring the MySQL server daemon to listen on that port. You can do so simply bypassing this same option to the mysqld daemon at startup time.• --socket=/path/to/socket, -s: For localhost connections, a socket file is required. OnUnix machines, this file is created in /tmp by default. On Windows machines, thisoption determines the name of the pipe (by default this name is MySQL) used for localconnections when named pipes are used.• --user=name, -u: Specifies the connecting user’s username.General OptionsThe following list highlights many of the options available to all or most clients. You can verify whether aparticular client supports a given option by outputting the client’s help page with the option --help.• --compress, -C: Enables compression for the protocol used for client/servercommunication.• --defaults-file=/path/to/configuration/file: At startup, each client typicallysearches in several locations for configuration files and applies the settingsaccordingly. You can override this behavior by specifying the location of aconfiguration file with this option.• --defaults-extra-file=/path/to/configuration/file: Reads this file after all otherconfiguration files have been read. You might use such a file during applicationtesting, for example.• --help, -?: Outputs help information before exiting. You can pipe the results througha pager to facilitate reading. For example, the following command takes advantage ofthe Unix more command to page output:%>mysql --help | more• --no-defaults: Ignores all configuration files.• --print-defaults: Outputs the options that will be used by the client as defined withinconfiguration files and environment variables.• --silent, -s: Decreases client chatter, or output. Note that this option does notnecessarily suppress all output.• --variable-name=value: Sets a variable’s value. Note that the option isn’t actuallycalled “variable-name.” Rather, this is intended as a placeholder for the name ofwhatever variable you’re trying to modify.• --verbose, -v: Outputs more output than would occur by default.• --version, -V: Exits after outputting client version information.522
