『楼 主』:
请教关于98 dos下 查询磁盘剩余空间的问题
各位大侠：
我目前遇到这样一个需求，在dos 系统下（dos version : Window 98 4.10.2222），在批处理文件中，查询一个磁盘（FAT,启动盘）剩余空间的大小，如果大于1G,提示用户。
通过这版本上DOS自带的命令或者外部命令（*.EXE 必须是免费允许各种用途）实现，熟悉的bat 编程的高手帮忙给点建议，谢谢哦
目前我有FIND.EXE,FDISK.EXE,CHKDSK.EXE等

非常感谢
1.我用for 语句，它提示是"syntax error"(如果没记错的话，总之提示错误)，
以你看，可能是什么原因
2.请教还有什么办法可以实现，谢谢！

可以用 4DOS 的 @diskfree 变量函数
| Quote: | 4DOS Help Topic: @DISKFREE
@DISKFREE[d:,b|k|m|g]: Returns the amount of free disk space on the
specified drive. DOS networks with large server disk drives (over 2 GB) may
report disk space values that are too small when @DISKFREE is used. If this
occurs, it is because the network software does not report the proper values
to 4DOS.

感谢 DOSforever！！！
1由于其他原因可能我无法使用4DOS.... 。
2.我今天重新试了下for 语句，如你所言，是可以使用的，只是功能比较弱的，
以下是 这个版本的 for 语句
Runs a specified command for each file in a set of files.
FOR %variable IN (set) DO command [command-parameters]
%variable Specifies a replaceable parameter.
(set) Specifies a set of one or more files. Wildcards may be used.
command Specifies the command to carry out for each file.
command-parameters
Specifies parameters or switches for the specified command.
To use the FOR command in a batch program, specify %%variable instead of
%variable.
3.我也找到的FIND.EXE
我想尝试通过for ,find 之类的DOS 内部或者外部命令实现，给点建议呀。
如果各位熟悉DOS bat 编程，提供些实现的示范呀，谢谢（本人不太熟悉DOS 编程，最近有临时需要才接触）

为什么无法使用 4DOS ？找不到下载？
你可以用“剩余空间”作为关键字在这个版块搜索一下。

呵呵，谢谢 fjdcxnp ，看来你还挺仔细的。我只记得 4DOS 从 7.50 版起就是 Freeware 了，还没注意到你说的“商业用途有限制”。我看了下你给的 4DOS 的 Wiki 链接，我的英文不太好，按照 History and current status 中这段话的意思
| Quote: | | Originally distributed as shareware, 4DOS has been later released as unsupported freeware. Currently, the source code is available under a modified MIT License but it "may not be used in any commercial product without written permission from Rex Conn" |
|
我的理解是，源代码不能用于商业产品，除非得到 Rex Conn 的许可，但 4DOS 软件本身是 Freeware 。

你看一下，如果使用的话会不会给你带来版权上的麻烦。

接下来我们再讨论下技术性问题
| Quote: | Originally posted by fjdcxnp at 2010-12-26 18:53:
1.我目前做的是在原有的bat file上添加些东西，如果改用4DOS可能会影响原有的应用，各种*.EXE |
|
关于改用 4DOS 后对原有 BAT 的影响，我是这么认为的：
http://www.cn-dos.net/forum/viewthread.php?tid=15214#pid91455
| Quote: | | 4DOS与传统的COMMAND.COM相比变化确实很大，但它并不是改变了COMMAND.COM原有的语法和参数，而是在它的基础上加以扩充，你也可以完全按照使用COMMAND.COM的习惯来使用它，原来在COMMAND.COM下编写的BATCH可以不加任何修改地在4DOS下运行…… |
|
当然，我本人没经过100%验证，具体你的应用还要你自己验证下。

|
BAT 根本算不上编程，编写批处理不叫编程，编写批处理根本上不了编程这个档次。在这里，我看到许多人要个什么批处理代码什么的，我对此嗤之以鼻，代码这个词我认为批处理还没这个资格用。

谢谢提供原版声明，我看了下，没发现什么问题，应该也能用
（与GNU还是不同的，不太确定），
谢谢
