Wildcard Patterns

Table 6.1 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.
