Command-line Syntax Conventions
This guide uses the following command-line syntax conventions.
 
Bars indicate “either | or” choices. For example:
Braces describe required syntax in which you have a choice and that at least one choice is required. For example:
In this example, you must choose option1, option2, or both options.
Absence of braces or brackets indicates required syntax in which there is no choice; you must type the required syntax element.
-merge filename1
-merge filename1, filename2 [, filename3 ... ]
where the ellipses specify, filename4, and so on.
The use of punctuation—such as single and double quotes, commas, periods—indicates actual syntax; it is not part of the syntax definition.
