Appendix B Using Wildcard
Patterns
This appendix describes the wildcard patterns used by the Sun Java System
Web Server. Wildcards use special characters and are applicable in the obj.conf file, built-in SAFs, and NSAPI functions. To use a wildcard character
without any special meaning, precede it with a backslash (\)
character.
This appendix has the following sections
Wildcard Patterns
The following table describes wildcard patterns, listing the patterns
and their uses.
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.
