Specify a command according to the following grammar rules:
-
If you specify multiple options, you can specify them in any order.
-
You cannot specify the same option more than once.
-
If you specify a non-existing option, an error occurs.
-
If you include a blank character in a value, surround a value with double quotation marks ("").
-
If you specify a command line special character such as an ampersand (&) and a circumflex accent (^), write the caret (^) before it.
-
You cannot use a double quotation mark (") for a value.
-
Specify a command so that its length does not exceed 8,191 characters.
-
If you specify multiple values for a single option, separate each value with a space.
-
If you specify multiple values for an option and when that option can have one value only, the value specified first is used. For an option that can have multiple values, all the values are used.
