- DOS 'n' Don'ts Part 7
- ---------------------
-
-
- Last month, we covered the Scratch,
-
- Copy, and Rename commands (among oth-
-
- ers). We showed how to use these com-
-
- mands with one file at a time. This
-
- month, we will not introduce any new
-
- commands, but will show how to specify
-
- more than one file at a time with the
-
- old commands.
-
-
- The secret to this is to use 'wild
-
- card' characters. A wild card in po-
-
- ker or other card games is a card that
-
- can stand for any other card. The wild
-
- card characters work the same way.
-
-
- The wild card characters are the
-
- question mark ('?') and the asterisk
-
- ('*'). The '?' can stand for any one
-
- character, and the '*' can stand for
-
- the remainder of a file name. For
-
- example: Suppose we have a disk in
-
- our drive that has 6 files, such that
-
- a directory listing (using DOS WEDGE)
-
- produces:
-
-
- 0 "MY OWN DISK " MD 2A
- 45 "FILE MAKER" PRG
- 9 "FIRE 1" PRG
- 3 "FILE 1" SEQ
- 6 "FILE 2" SEQ
- 5 "FILE 3" SEQ
- 12 "FILLER" PRG
- 3 "JUNQUE" PRG
- 601 BLOCKS FREE.
-
-
- With the above directory, the fol-
-
- lowing filenames produce the following
-
- matches:
-
-
- FILENAME MATCES
- -------- ------
-
- '*' all files
-
- 'F*' everything except
- 'JUNQUE'
-
- 'FILE *' 'FILE MAKER'
- 'FILE 1'
- 'FILE 2'
- 'FILE 3'
-
- 'FILE ?' 'FILE 1'
- 'FILE 2'
- 'FILE 3'
-
- 'FIL???' 'FILE 1'
- 'FILE 2'
- 'FILE 3'
- 'FILLER'
-
- 'FI?E*' 'FILE MAKER'
- 'FIRE 1'
- 'FILE 1'
- 'FILE 2'
- 'FILE 3'
-
- '??????' everything except
- 'FILE MAKER'
-
- Note that an asterisk is the same
-
- as enough question marks to finish out
-
- a 16-character file name. Contrary to
-
- the manual, you cannot put an asterisk
-
- anywhere except as the last character.
-
- For example, you could NOT use the
-
- filename 'FIL*ER' to match both 'FILE
-
- MAKER' and 'FILLER'.
