要总揽

让我们学习一些重要指令,可能有用,而我们正尝试恢复数据编程编程技术和无:

ATTRIB

attrib是用来展示的指挥、集,或排除一个或一个以上的四个属性,只读、档案馆、 制度、隐蔽,能够分配到档案和通讯录.它通常用来清除只读、隐藏、并制做一个档案属性可移动或删除,或把它们也使我们不能.

语法:

显示属性设置在目前所有档案目录:

ATTRIB

展示属性名录:

ATTRIB directoryname

To display the attributes of a file:

ATTRIB filename

确定属性或删除一个文件或目录:

ATTRIB [ + | - R] [ + | - A] [ + | - S] [ + | - H] [directory|filename] [/S]
+ Sets an attribute, - Clears an attribute.

R

Read-only file attribute.

A

Archive file attribute.

S

System file attribute

H

Hidden file attribute.

/S

Processes files in all directories in the specified path.

该只读属性允许查阅档案但不修饰.属性通常保留给系统所需要的档案或民政视窗装好.档案目录与隐藏属性通常不会订上市或公开展示档案目录对话盒.

通常的原因是因为他们躲在夹重要制度或程序运作,不能随便删除或迁入清理作业.隐藏和系统文件夹往往也只读属性集.

多重属性可结合清理或交换机,隔着位. 虽然档案及通讯录可以使用attrib属性分配和清理、 他们有不同的表现方式--其中最明显的是,借以反应(? 和*)可以用来显示或改变属性为一组,而档案目录必须命名照准. 我们要知道详情,借以反应本章稍后捷径.

档案属性设定为系统隐藏或只读,防止档案被删除或用del动议,抹去,或者移动指令,但不会从保护档案格式或者deltree.虽然目录的只读属性可确定,这似乎不大.

第一,属性,而不是仅适用于目录内的档案.还制定了以夹只读被删除,但并不妨碍它在Windows探险它将导致展示的警告之前夹被删除或迁移.

展示档案属性取名为"readme":

ATTRIB readme

转让只读属性的档案"readus.txt",使用:

ATTRIB readus.txt +R

清除系统和隐藏属性由"data19.txt":

ATTRIB -S -H data19.txt

To hide the directory "c:\mynotes"

ATTRIB +H c:\mynotes

隐藏档案,但不是在三通讯录:

ATTRIB +H c:*.*

CD (or CHDIR)

改变现行的目录(或显示器)在指定径.

语法:

显示当前目录:

CD [drive:]

改变现行目录:

CD path

为了改变当前目录路径路径. 每个驾驶都有自己的"当前目录",仍然是"当前",直到它改变从而改变目前名录径三: 当前目录地位并不影响其他任何活动.为了改变当前目录不同径,刚刚进入径信和结肠.

If the current drive is c:, to enter the directory "c:\windows\java"
CD \windows\java

如果当前目录已经"丙:\窗口",即所有必要的:

CD java

改变现行名录的"C:\窗户\爪哇"母体名录"丙:\窗口":

CD..

假如你正主任的"C:\窗户\爪哇\债券\Klip\",现在如果你想直接跳向窗户名录、 只是增加两个点(..)你像上次一样,这
CD….

如果目前名录>三:径是"丙:\窗户\笔记"和目前的电子目录: 径是"电子:\电影",那么所有的档案拷贝从"电子:\电影"向"三\窗户\笔记":

COPY e:*.* c:

所有档案拷贝从"电子:\下载"三根目录:

COPY e:*.* c:\
