To read a syntax diagram for entering a command, follow the path of the line. Read from left to right and from top to bottom.
Enter these symbols exactly as they appear in the syntax diagram.
Italicized lowercase items such as <var_name> indicate variables. In this example, you can specify a <var_name> when you enter the cmd_name command.
>>-cmd_name--<var_name>----------------------------------------><
An arrow returning to the left means that the item can be repeated. A character within the arrow means that you must separate repeated items with that character.
.-,------. V | >>---repeat-+--------------------------------------------------><
A footnote (1) by the arrow refers to a limit that tells how many times the item can be repeated.
.-,------------. V (1) | >>---------repeat-+--------------------------------------------><
When two or more items are in a stack and one of them is on the line, you must specify one item.
When an item is below the line, that item is optional. In the first example, you can select A or nothing at all.
>>-cmd_name--+---+--------------------------------------------->< '-A-'
A stack of items followed by an arrow returning to the left indicates that you can select more than one item, or in some cases, repeat a single item.
In this example, you can select any combination of A, B, or C.
.-,-----. V | >>-cmd_name----+-A-+-+----------------------------------------->< +-B-+ '-C-'
Defaults are above the line. The default is selected unless you override it, or you can select the default explicitly. To override the default, include an option from the stack below the line.
In this example, A is the default. Select either B or C to override A.
.-A-. >>-cmd_name--+---+--------------------------------------------->< +-B-+ '-C-'
