Appendix B Wildcard Patterns

This appendix describes the format of wildcard patterns used by the Sun Java System Application Server.

Wildcard patterns use special characters. If you want to use one of these characters without the special meaning, precede it with a backslash (\) character.

Wildcard Patterns

Table B-1 Wildcard Patterns
Pattern	Use
*	Match zero or more characters.
?	Match exactly one occurrence of any character.
\|	An or expression. The substrings used with this operator can contain other special characters such as * or $. The substrings must be enclosed in parentheses, for example, (a\|b\|c), but the parentheses cannot be nested.
$	Match the end of the string. This is useful in or expressions.
[abc]	Match one occurrence of the characters a, b, or c. Within these expressions, the only character that needs to be treated as a special character is ]; all others are not special.
[a-z]	Match one occurrence of a character between a and z.
[^az]	Match any character except a or z.
*~	This expression, followed by another expression, removes any pattern matching the second expression.

Wildcard Examples

Table B-2 Wildcard Examples
Pattern	Result
*.sun.com	Matches any string ending with the characters .sun.com.
(quark\|energy).sun.com	Matches either quark.sun.com or energy.sun.com.
198.93.9[23].???	Matches a numeric string starting with either 198.93.92 or 198.93.93 and ending with any 3 characters.
.	Matches any string with a period in it.
~sun-	Matches any string except those starting with sun-.
*.sun.com~quark.sun.com	Matches any host from domain sun.com except for a single host quark.sun.com.
*.sun.com~(quark\|energy \|neutrino).sun.com	Matches any host from domain .sun.com except for hosts quark.sun.com, energy.sun.com, and neutrino.sun.com.
.com~.sun.com	Matches any host from domain .com except for hosts from subdomain sun.com.
type=~magnus-internal/	Matches any type that does not start with magnus-internal/. This wildcard pattern is used in the file obj.conf in the catch-all Service directive.
