Displays or sets the search path for data files. DOS will search the specified path(s) if the file is not found in the current path.
显示或设定资料文件的搜寻路径. 如果这文件不在当前的目录中, DOS 会在指定好的路径(s)中搜索。
ASSIGN
(External)
ASSIGN x=y [...] /sta
Redirects disk drive requests to a different drive.
重定向硬盘(重新分配一个盘符)
Makes a backup copy of one or more files. (In DOS Version 6, this program is stored on the DOS supplemental disk.)
制作一个或多个备份文件. (在DOS6.xx 版本中, 这程序是储存在于DOS的补充磁盘中.)--KO的话:这好像是说这个程序不是标准配置下(标准DOS系统盘)的
DOS外部命令, 而是在附加的DOS系统盘里的命令。
CHKDSK
(External)
CHKDSK [d:][path][filename] [/F][/V]
Checks a disk and provides a file and memory status report.
检查磁盘和提供一文件和记忆体(内存)状态报告.
Starts a new version of the DOS command processor (the program that loads the DOS Internal programs).
开始一新的版本之这DOS 命令处理器(这程式那载入这DOS 内部程式).
KO的话:这个翻译不容易懂。开机时(启动时)在DOS下面会自动装入command.com这个程序,用来解释各种命令的执行。但你还可以在这个环境下再运行一个
command的副本(这个也不容易懂),就是说你还可以在命令提示符下敲入command这个命令,它会再创造一个解释命令执行的环境。在你敲入command这个命令后
,你以后敲入的命令都在这个command的环境中解释执行,除非你敲入EXIT这个命令。(这个命令告诉command,该结束了,你应该返回到最初的那个command的环
境中去了。)这有点象一些DOS软件提供的DOS SHELL 功能一样。(shell ,壳,环境)

Displays amount of installed and available memory, including extended, expanded, and upper memory.
显示已用的和空闲的内存空间,包括扩展内存,扩充内存和上位内存。 --KO的话:扩展和扩充内存的概念最容易搞混,我现在也搞混了,
不知道到底是extended对应的是扩展还是扩充。下次看到了有关资料后再说吧。
Provides detailed technical information about your computer.
提供你的计算机的技术上的详细信息。--KO的话:就是检查你的电脑上的硬件和软件信息。就像windows下的system information系统信息一样)

这篇帖子大家看看就算了。。。
不懂的话也没关系,反正很少用到这些命令。
其中有些常用的,到时再详细一点讲吧。反正第六课计划还是讲外部命令的。呵呵。。。作者: ko20010214 时间: 2003-6-11 00:00 下面的英文也是来自 http://www.easydos.com/dosindex.html
英文好的可以看看。
中文翻译是用CXW_READ这个软件翻译的。这个软件翻译的质量,唉。

Syntax Notes
To be functional, each DOS command must be entered in a particular way: this command entry structure is known as the command's "syntax." The syntax "notation" is a way to reproduce the command syntax in print.
For example, you can determine the items that are optional, by looking for information that is printed inside square brackets. The notation [d:], for example, indicates an optional drive designation. The command syntax, on the other hand, is how YOU enter the command to make it work.
Command Syntax Elements
1. Command Name
The DOS command name is the name you enter to start the DOS program (a few of the DOS commands can be entered using shortcut names). The DOS command name is always entered first. In this book, the command is usually printed in uppercase letters, but you can enter command names as either lowercase or uppercase or a mix of both.
2. Space
Always leave a space after the command name.
3. Drive Designation
The drive designation (abbreviated in this book as "d:") is an option for many DOS commands. However, some commands are not related to disk drives and therefore do not require a drive designation. Whenever you enter a DOS command that deals with disk drives and you are already working in the drive in question, you do not have to enter the drive designator. For example, if you are working in drive A (when the DOS prompt A> is showing at the left side of the screen) and you want to use the DIR command to display a directory listing of that same drive, you do not have to enter the drive designation. If you do not enter a drive designation, DOS always assumes you are referring to the drive you are currently working in (sometimes called the "default" drive).
4. A Colon
When referring to a drive in a DOS command, you must always follow the drive designator with a colon (:) (this is how DOS recognizes it as a drive designation).
5. Pathname
A pathname (path) refers to the path you want DOS to follow in order to act on the DOS command. As described in Chapter 3, it indicates the path from the current directory or subdirectory to the files that are to be acted upon.
6. Filename
A filename is the name of a file stored on disk. As described in Chapter 1, a filename can be of eight or fewer letters or other legal characters.
7. Filename Extension
A filename extension can follow the filename to further identify it. The extension follows a period and can be of three or fewer characters. A filename extension is not required.
8. Switches
Characters shown in a command syntax that are represented by a letter or number and preceded by a forward slash (for example, "/P") are command options (sometimes known as "switches"). Use of these options activate special operations as part of a DOS command's functions.
9. Brackets
Items enclosed in square brackets are optional; in other words, the command will work in its basic form without entering the information contained inside the brackets.
10. Ellipses
Ellipses (...) indicate that an item in a command syntax can be repeated as many times as needed.
11. Vertical Bar
When items are separated by a vertical bar (|), it means that you enter one of the separated items. For example: ON | OFF means that you can enter either ON or OFF, but not both.
