Wildcards

There's a way to refer to more than file at a time with the magic known as wildcards. Wildcards are a way of specifying part of any filename to be included in a command for processing. Actually, there are two wild cards. They are:

  • Asterisk (*)

  • Question mark (?)

The question mark will match any single character in a filename, while the asterisk* will match any number of characters that may exist. For example, consider this file list:

  • JAN1.DOC

  • JAN10.DOC

  • JUNE1.DOC

  • JUNE10.DOC

  • JUNE 30.DOC

  • JULY1.TXT

Entering COPY J*.* would copy all the files listed above. Typing COPYJ*.doc would copy all but the file JULY 1.TXT. The command COPY JAN?.* would only copy JAN1.DOC and not JAN10.DOC .
