Appendix C   Wildcard Patterns

This appendix describes the format of wildcard patterns used by the iPlanet Web Server.

These wildcards are used in:

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 C-1    Wildcard patterns




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.  


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.  


Match one occurrence of a character between a and z.  


Match any character except a or z.  


This expression, followed by another expression, removes any pattern matching the second expression.  

Wildcard Examples
