Symbols

You may see a variety of symbols shown as part of the command syntax. These symbols usually explain how to enter the command, and you do not type them as part of the command itself. The exceptions to this rule are parentheses, the hyphen, and the exclamation point, which you do type as part of the command. Table 3 summarizes command syntax symbols.

Table 3 Command Syntax Symbols

Symbol	Description
angle brackets < >	Enclose a variable or value. You must specify the variable or value; for
	example, in the syntax:
	DELete -IP ADDRess <IP address>
	you must supply an address for <IP address> when you enter the
	command. Do not type the angle brackets.
square brackets[ ]	Enclose an optional value or a list of optional arguments. One or more
	values or arguments can be specified. For example, in the syntax:
	SET PRIvilege = [User NetMgr]
	you can specify either User or NetMgr when you enter the command. Do
	not type the square brackets.
parentheses ( )	Enclose a list of values that can be assigned to a single parameter. At least
	one of them must be selected. You must type the parentheses and
	separate the values with a comma if you are assigning more than one
	value. For example, in the syntax:
	SET CurrentPorts = ALL (<port>, <port>)
	you can specify two port numbers by enclosing them in parentheses and
	separating them with a comma when you enter the command.
vertical bar	Separates mutually exclusive items in a list, one of which must be
	entered. For example, in the syntax:
	SET ScreenLength = [None <line>(6–100)]
	you can specify either the word None or a number between 6 and 100
	when you enter the command. Do not type the vertical bar.
ellipsis ...	Following a parameter name or value, indicates that one or more
	additional arguments may be specified on the same command line. For
	example, in the syntax:
	ADD !<port> -IP SecAuthIn <authority> [<authority> ...	]
	[ANY]

you can specify multiple authorities (GENSER, SIOP, SCI, NSA, DOE, NONE) when you enter the command. Do not type the ellipsis.
