一批民政司令部之间航行时承认某些捷径名录.其中最著名的有:

  Shortcut捷径

Wildcards

像许多指挥民政、attrib、仿造、del、deltree等,接受使用"借以反应"(*、?) .普遍而言,*指多字? 一个字指一个单一档案或目录名称.

这就是为什么我们不能使用这些人物的名字任何档案.这些特殊人物/\:*?"|不应试图插入一个档案名称. 下表使用借以反应:

Wildcard外卡

What it does究竟是什么

*.*

All files with all extensions.所有档案与所有分机.

*data*.**数据*.*

All files with "data" anywhere in its name.所有档案"资料"地方名称.

*array.*数组**

All files with names ending with "array"所有档案名称与结尾"阵"

note?.cpp注?.柬埔寨

All files named "note" plus one character and with .CPP extensions.所有档案命名为"注"字,加一.柬埔寨分机. This file may be note1.cpp, but not note.cpp.这个档案可能note1.cpp,但不是note.cpp.

?t*.*?笔*.*

All files with an "t" as second letter in their names所有档案的"笔"作为自己的名字在第二封信


应当指出,并非所有的指挥处理借以反应一样. 例如迪尔迪尔**del*.*将被视为同义词,但只删除档案而未延期.

一个密闭空间由引号("")是接受为有效规范了档案整理、del但相当不同.

EDIT will open a file using the name of the current directory. Thus if the current directory is D:\windows\java\notes, EDIT " " will create a file in that directory called "notes".

del承认""*.*将删除所有之前及时确认档案目录.同编辑 数位之间的引号似乎并不重要,但如果没有空间,是一项错误的讯息,说了所需参数展出失踪.

不像编辑,可以包括路径,如果它没有引号位之间需要.即删除所有的档案,在当前目录:

DEL ./"" works, but DEL "" gives an error message.

副本也看好""*.*,象del,接受了道路. 不像del,一定要有一个太空之间引号,即使包括了道路
