Wildcarded Strings

A wildcarded string consists of a sequence of alternating wildcard specifiers and strings. The sequence can start with either a wildcard specifier or a string, and end with either a wildcard specifier or a string.

The wildcard specifier is denoted by the asterisk character (*) and means 0 or more occurrences of any character.

Wildcarded strings can be used to specify substring matches. Table 2–8 contains examples of wildcarded strings and their meaning.
