This appendix describes the wildcard patterns used by 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
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. |
The following table provides wildcard examples, listing the pattern and the result.
