–plugin-dir=name Directory for client-side plugins.
–default-auth=name Default authentication client-side plugin to use.
–binary-mode By default, ASCII ‘\0’ is disallowed and ‘\r\n’ is

piped to mysql or loaded using the ‘source’ command).
This is necessary when processing output from mysqlbinlog
that may contain blobs.
Notify the server that this client is prepared to handle
expired password sandbox mode.
Network namespace to use for connection via tcp with a
Use compression algorithm in server/client protocol.
Valid values are any combination of
Use this compression level in the client/server protocol,
in case –compression-algorithms=zstd. Valid range is
between 1 and 22, inclusive. Default is 3.
Directory path safe for LOAD DATA LOCAL INFILE to read
Specifies authentication factor, for which registration
needs to be done.
Specifies the configuration profile whose configuration
options are to be read from the OCI configuration file.
Default is DEFAULT.
Specifies the location of the OCI configuration file.
Default for Linux is ~/.oci/config and %HOME/.oci/config
on Windows.

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 client
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,
except for login file.
