命令提示符不会更改目录 [英] Command Prompt Won't Change Directory

问题描述

我正在尝试编译一些java（目前正在学习java），为此我需要更改命令提示符的目录（使用javac）。

I'm trying to compile some java (learning java currently), and to do so I need to change command-prompt's directory (using javac).

C:\...\Admin> cd D:\Docs\Java
C:\...\Admin> cd
C:\...\Admin

它不会更改目录。我再次尝试使用引号：

It doesn't change the directory. I try again using quotes:

C:\...\Admin> cd "D:\Docs\Java"
C:\...\Admin>

再次，它不会更改目录。我做错了什么？

Again it doesn't change the directory. What am I doing wrong?

推荐答案

As @nasreddine 回答，或者您可以使用 / d

As @nasreddine answered or you can use /d

cd /d d:\Docs\Java

有关 cd 命令使用：

C:\Documents and Settings\kenny>help cd

显示当前目录的名称或更改当前目录。

Displays the name of or changes the current directory.

CHDIR [/ D] [drive：] [path]
CHDIR [..]
CD [/ D] [drive：] [path]
CD [..]

CHDIR [/D] [drive:][path] CHDIR [..] CD [/D] [drive:][path] CD [..]

..指定要更改为父目录。

.. Specifies that you want to change to the parent directory.

键入CD驱动器：在指定的驱动器中显示当前目录。
键入CD，无参数显示当前驱动器和目录。

Type CD drive: to display the current directory in the specified drive. Type CD without parameters to display the current drive and directory.

除了更改当前
目录之外，还可以使用/ D开关更改当前驱动器一个驱动器。

Use the /D switch to change current drive in addition to changing current directory for a drive.

如果启用了命令扩展名CHDIR更改如下：

If Command Extensions are enabled CHDIR changes as follows:

当前目录字符串被转换在
上使用与磁盘名称相同的大小写。所以CD C：\TEMP实际上会将当前的
目录设置为C：\Temp，如果是磁盘上的情况。

The current directory string is converted to use the same case as the on disk names. So CD C:\TEMP would actually set the current directory to C:\Temp if that is the case on disk.

CHDIR命令不将空格视为分隔符，因此可以将
CD转换为包含空格的子目录名称，而不包含
带有引号的名称。例如：

CHDIR command does not treat spaces as delimiters, so it is possible to CD into a subdirectory name that contains a space without surrounding the name with quotes. For example:

cd \winnt\profiles\username\programs\start菜单

cd \winnt\profiles\username\programs\start menu

与以下相同：

cd\winnt\profiles\username\programs\start菜单

cd "\winnt\profiles\username\programs\start menu"

如果扩展程序被禁用，那么您将如何输入。

which is what you would have to type if extensions were disabled.
