在DOS時代通配符是搜索的必備參數(shù)，到現(xiàn)在還是在很多場合使用。
當我們看到wildcard這個單詞時，可能會感到費解，從字面上看是“野的”、“卡片”，怎么會跟計算機有什么關系，莫名其妙。
下面就介紹一下這個家伙：
通配符
wildcard character
定義：
A special symbol that stands for one or more characters. Many operating systems and applications support wildcards for identifying files and directories. This enables you to select multiple files with a single specification. For example, in DOS and Windows, the asterisk (*) is a wild card that stands for any combination of letters. The file specification
m*
therefore, refers to all files that begin with m. Similarly, the specification
m*.doc
refers to all files that start with m and end with.doc.
Many word processors also support wild cards for performing text searches.
例子：
(wildcard characters * and ? allowed, see examples)
