HP-UX AAA Server A.08.01 administrator's guide (T1428-90072, May 2010)

Attribute instance specifications are provided using the [] syntax, after the attribute
name. The instance of interest is indicated inside the square brackets ([]). You can
specify an attribute instance in one of the following ways:
• “No Instance Specification.”
• “Numeric Instance Specification.”
• “Keyword Instance Specification” (page 423)
While specifying attribute instance specifications, ensure that there is no white space
around and between the square brackets ([]).
No Instance Specification
You need not specify a specific instance if it is of no consequence. The no instance
specification is equivalent to specifying the last keyword. For more information on
the last keyword, see “Keyword Instance Specification.”
Numeric Instance Specification
When a specific instance is required, you can specify it numerically. Instances are
numbered from 0 (the first instance). Negative instance numbers are not allowed.
Keyword Instance Specification
When a specific instance is required, it can be specified using one of the following
keywords, or by using the asterisk (*) symbol:
• The begin keyword: If you want to specify an attribute instance located at the
beginning of the list, use the begin keyword. This keyword is supported only by
the insert command, on the left side of the = operator. Following is an example
of a correctly formatted keyword instance specification:
insert Reply-Message[begin] = "This is first"
For more information on the insert command, see “The insert Command”
(page 415).
Using the begin keyword with other commands results in an
invalid-instance-specification load-time error.
• The last keyword: If you want to specify the last instance of an attribute , use
the last keyword. Following is an example of a correctly formatted keyword
instance specification:
Reply-Message[last]
NOTE: This is the default value if no keyword is specified.
• The asterisk keyword: If you want to specify all instances of an attribute, use the
asterisk (*) symbol. The following example specifies all instances of the
Reply-Message attribute:
Reply-Message[*]
