当把程序放在带空格的目录下执行时,当输入的路径为 当前盘符+冒号的时候,并不能禁止全盘复制.而放到不带空格的目录下执行,或者是输入的路径为 任意盘符+冒号+\的时候,则没问题,不知道是为什么.

When the program is executed in a directory with spaces, when the entered path is current drive letter + colon, it cannot prevent full disk copying. But when it is executed in a directory without spaces, or when the entered path is any drive letter + colon + \, there is no problem. I don't know why.

Re namejm:
这其中的原因在于，路径中的单纯使用盘符+冒号就意味着引用的是所指定磁盘的当前路径。所以在命令行直接使用盘符+冒号，会跳转到所指定磁盘的当前路径，而并非一定是根路径。
所有存在的磁盘都有当前路径，并且同时有效；当我们未用cd或其它方式改变它时，通常为根路径。使用cd "d:\Program files"会改变D盘的当前路径，而不论当前盘是否是D盘；也而使用copy c:*.* d:会将C盘当前路径下所有文件拷贝到D盘当前路径下，而不论当前处于哪个盘。
这应该算是一个固有的路径引用技巧，从DOS到CMD一直存在，如同. 和..一样。如果你想将d:转义为d盘根路径，相当于改变了命令行的固有约定，反而会对某些人造成困扰。我的新代码中有意测试了非当前盘的当前路径非根路径时的表现（E盘下测试当前路径为“C:\Documents and Settings”的C盘），结果我是满意的，它没有跳到forbid。
Re namejm:
The reason for this is that simply using a drive letter + colon in the path means that the current path of the specified disk is being referenced. So using a drive letter + colon directly in the command line will jump to the current path of the specified disk, not necessarily the root path.
All existing disks have a current path, and they are all valid at the same time; when we have not changed it using cd or other methods, it is usually the root path. Using cd "d:\Program files" will change the current path of drive D, regardless of whether the current drive is D or not; and using copy c:*.* d: will copy all files in the current path of drive C to the current path of drive D, regardless of which drive you are currently on.
This should be considered an inherent path reference technique that has existed from DOS to CMD, just like. and.. do. If you want to escape d: to the root path of drive D, it is equivalent to changing the inherent convention of the command line, which will instead cause confusion for some people. In my new code, I intentionally tested the performance when the current path of a non-current drive is not the root path (testing drive E with the current path of drive C being "C:\Documents and Settings"), and the result is satisfactory, it did not jump to forbid.

『第 21 楼』:
[求助]怎么提取at命令中"命令行"栏目下的路径?
使用 LLM 解释/回答一下
想把at命令中"命令行"栏目下的路径提取出来,先把at命令结果倒出到一文本文件中,发现格式如下:
状态 ID 日期 时间 命令行
-------------------------------------------------------------------------------
1 每月执行日期: 1 2 3 4 5 6 7...12:40 C:\WINDOWS\system32\家易理财数据备份.bat
2 每月执行日期: 1 2 3 4 5 6 7...19:00 C:\WINDOWS\system32\家易理财数据备份.bat
3 每月执行日期: 1 2 3 4 5 6 7...22:00 C:\WINDOWS\system32\家易理财数据备份.bat
其间有几个方块黑点 (直接copy以上内容保存为文本文件不会出现,但是如果是用at>list.txt命令的话,会发现有方块黑点存在),不知道该格式的行与列是用什么分割的,导致无法用for命令来提取.
请问,我该怎么办?
如果能不产生临时文件就能提取的话,就更好了.
上述问题已经找到了一个解决办法,但是还不够完善,因为还是会产生临时文件,代码如下:
@echo off
del /q "%tmp%\list.txt">nul 2>nul
at>"%tmp%\list.txt"
(for /f "skip=2 tokens=4 delims=\" %%i in (%tmp%\list.txt) do (find /i "Code by JM" %systemroot%\system32\%%i >nul 2>nul && echo %%i由特定程序创建))
del /q "%tmp%\list.txt">nul 2>nul
pause>nul
Last edited by namejm on 2006-5-27 at 11:04 ]
I want to extract the path in the "Command Line" column in the at command. First, I export the result of the at command to a text file, and find the format as follows:
Status ID Date Time Command Line
-------------------------------------------------------------------------------
1 Monthly execution date: 1 2 3 4 5 6 7...12:40 C:\WINDOWS\system32\Jiayi Financial Data Backup.bat
2 Monthly execution date: 1 2 3 4 5 6 7...19:00 C:\WINDOWS\system32\Jiayi Financial Data Backup.bat
3 Monthly execution date: 1 2 3 4 5 6 7...22:00 C:\WINDOWS\system32\Jiayi Financial Data Backup.bat
There are several square black dots in between (Directly copying the above content and saving it as a text file will not have them, but if you use the at>list.txt command, you will find that there are square black dots). I don't know what is used to separate the rows and columns in this format, which makes it impossible to use the for command to extract.
What should I do?
It would be even better if I can extract without generating temporary files.
The above problem has found a solution, but it is not perfect because temporary files are still generated. The code is as follows:
@echo off
del /q "%tmp%\list.txt">nul 2>nul
at>"%tmp%\list.txt"
(for /f "skip=2 tokens=4 delims=\" %%i in (%tmp%\list.txt) do (find /i "Code by JM" %systemroot%\system32\%%i >nul 2>nul && echo %%i created by a specific program))
del /q "%tmp%\list.txt">nul 2>nul
pause>nul

用了如下命令:

用at命令查看清单,结果如下:

难道是我的电脑显示不正常吗?
(另:在论坛里用插入图象的功能,似乎只能插入网络上的图片,难道就不能插入本机上的吗?)
The commands used are:

When checking the list with the at command, the result is as follows:

4 Execution date of every month:... 22:00 c:\windwos\system32\家易理财数据备份.bat
Is it that my computer is not displaying normally?
(Another thing: When using the function to insert an image in the forum, it seems that only images on the network can be inserted. Can't I insert local ones?)

Last edited by namejm on 2006-5-27 at 10:58 ]
Assuming the files are in a text format, in a batch script (using Windows batch commands), you could do something like this (but this is a simplified example, adjust according to actual situation):
```batch
@echo off
findstr "C:\WINDOWS\system32\test.bat" 2.txt > extracted.txt
```
This would find the line containing "C:\WINDOWS\system32\test.bat" in 2.txt and put it into extracted.txt. But if you are using a programming language like Python, it could be:
```python
with open('2.txt', 'r') as f:
content = f.read()
target_line =
if target_line:
with open('extracted.txt', 'w') as f_out:
f_out.write(target_line)
```
This Python code reads the content of 2.txt, finds the line that contains the target path, and then writes that line to extracted.txt. Please note that the actual implementation may need to be adjusted according to the specific operating environment and more detailed requirements.

xcopy复制了0个文件也算执行成功吗?
使用 LLM 解释/回答一下
发现了一个问题:
当没有更新备份的时候,即xcopy执行后提示"复制了0个文件"的时候,按照我的本意,是不用在log.txt文件里写入任何内容的,结果却写入了内容,难道xcopy复制了0个文件的时候也算执行成功吗?如果也算的话,&&及其之后的内容该怎么写?
Last edited by namejm on 2006-5-28 at 17:17 ]
Found a problem:
When there is no updated backup, that is, when xcopy prompts "0 files copied", according to my intention, I don't need to write any content in the log.txt file, but it actually writes content. Does xcopy count as successful when copying 0 files? If it does, how should && and the subsequent content be written?

Re namejm:
21楼at命令的记录输出，是以换行符（ASCII:0A）而非回车换行符（ASCII:0D 0A）作为行结束，而记录域之间以普通的空格界分。因为记事本工具只能识别回车换行符，所以行被粘接显示，但是在我的测试中，这并不影响for对at命令输出的识别。以下命令是正常执行的。
for /f "skip=2 delims=\ tokens=4" %%f in ('at') do ...
22楼的第4条记录显示，是因为三个执行日（星期一 星期二 星期三）无法同时显示，所以用省略号替代显示，不影响任务的属性。如果你想抽取任务的执行日，则需要其它的方法。
23楼的差异比较，那要看文件属何种差异类型，是文件2.txt总大于1.txt，还是1/2互有不同内容，相同记录是否在同一行等？这决定了代码的复杂度。
24楼xcopy的返回值确实是这样的规则，因为它找到了源文件，并且复制过程中没有出现错误或被用户中止。暂时解决的办法是用find/findstr过滤xcopy输出结果。
xcopy /d /h /i /k /f /s /y "%source%" "%destination%" | find "->">nul && (...
Re namejm:
The record output of the at command on floor 21 uses newline characters (ASCII: 0A) instead of carriage return newline characters (ASCII: 0D 0A) as line endings, and the record fields are separated by ordinary spaces. Because the notepad tool can only recognize carriage return newline characters, the lines are displayed stuck together, but in my test, this does not affect the for to recognize the at command output. The following command executes normally.
for /f "skip=2 delims=\ tokens=4" %%f in ('at') do ...
The 4th record on floor 22. It is because the three execution days (Monday Tuesday Wednesday) cannot be displayed at the same time, so it is replaced with an ellipsis, which does not affect the task attributes. If you want to extract the execution days of the task, you need other methods.
The difference comparison on floor 23 depends on what type of difference the file is, whether file 2.txt is always larger than 1.txt, or 1/2 have different contents from each other, whether the same records are in the same line, etc.? This determines the complexity of the code.
The return value of xcopy on floor 24 is indeed such a rule, because it found the source file and there were no errors or being aborted by the user during the copying process. The temporary solution is to use find/findstr to filter the xcopy output results.
xcopy /d /h /i /k /f /s /y "%source%" "%destination%" | find "->">nul && (...

2.txt总是大于1.txt
我的本意是:检测at任务中用到的bat批处理程序,提取"命令行"栏目下的bat文件名,然后和%systemroot%\system32目录下的bat文件作个比较,如果不在at任务栏中,并且是本程序创建的(标志符为Code by JM) ,则删除该bat文件.

2.txt is always larger than 1.txt
My original intention is: detect the bat batch processing program used in the at task, extract the bat file name in the "Command Line" column, and then compare it with the bat file in the %systemroot%\system32 directory. If it is not in the at task column and is created by this program (identifier is Code by JM), then delete the bat file.
How to handle this?
