Tried it a few more times and found that the reason the first code segment for /f %%i in ('dir /a /b %systemroot%\system32\*.bat') do (find /i "Code by JM" %%i >nul 2>nul && echo %%i was created by a specific program) couldn't execute is that %%i is just the file name, and the full path should be included. Changing %%i to %systemroot%\system32\%%i achieved the expected goal.

The second code segment can achieve the expected goal, but when testing, the specific programs were all in the at scheduled tasks. Later, a test.bat file with only "code by jm" in it was manually created for testing, and it passed completely. It seems that when I was testing before, I was careless, missed some conditions, and did a lot of useless work.

Thank the moderator for continuing to pay attention to this post, which has made many functions in my script improved in time.

This backup script has covered file path check, boot automatic update, regular update, log update, remaining space check, backup task uninstall... It is relatively complete. I plan to make changes today and then will not update this script anymore.

echo Wscript.Echo UCase("%subarea2%")>~Upper.vbs 

for /f "tokens=*" %%a in ('cscript //nologo ~Upper.vbs') do set subarea2=%%a 

for %%f in (~Upper.vbs*) do del %%f

Re namejm:

OK! Since brother intends to release the June 1 final version, to show support, I provide two more suggestions.

Noted that: the change_character segment is only called once in the :subarea_noexist segment, and the drive letter %subarea2% is only echoed once, so there seems to be no need for UpperCase; if there are other reasons, then another more concise solution is recommended.

Also, the comment content in the script has been re-formatted according to the line width of 78 .
UpperCase

echo Wscript.Echo UCase("%subarea2%")>~Upper.vbs 

for /f "tokens=*" %%a in ('cscript //nologo ~Upper.vbs') do set subarea2=%%a 

for %%f in (~Upper.vbs*) do del %%f

Re namejm:

A simple test was performed on version 1.7, and the following issues were encountered:

First, when generating a backup task, an error message was output. After verification, it was because: three lines of code in the build_batch segment were wrapped, and the part of the output file name was truncated. After fixing, the original problem disappeared.

Second, when entering the backup date, it is not possible to only back up on the first day of each month because 1 is assigned to the function of returning to the previous step. In addition, there is also a problem that the setting functions of function keys under different interfaces are not unified, such as 1 and 0, and they may be used as input for dates, task IDs or other normal contents, so it is recommended to use other keys.

Third, there seems to be a problem when adding a backup task in the registry Run item. The batch processing of the backup task has no time control statement, which may cause a backup to be executed every time it is started, which may not be what the user wants. At the same time, after uninstalling a certain task, the relevant startup item is not cleared. If you want to avoid incorrect backup time, you need to judge the task requirements every time you start, which obviously increases the complexity of the task batch processing. Therefore, it is recommended to write the time judgment and backup task module into the main batch processing, and only call the corresponding module in the task batch processing.

In addition, when backing up the folder, the folder itself was not backed up. This may be what the user wants or not, but the customary practice is to keep the structure of the backup target complete, and the folder itself is obviously part of the structure. Some adjustments need to be made to the xcopy statement.

Finally, considering that there are many important files in system32, once there is an error in the program operation, it is very likely to cause a greater impact on the system, and it is difficult to find the batch processing for debugging from it. It is recommended that %batch_directory% be selected from one of the paths such as the temporary directory %temp%, the current path., the program's path %~dp0, and %APPDATA%\%~n0. If it is necessary in the default search path, it can be placed under %systemroot%.

set source=

set /p source=           请输入要备份文件的路径：

if "%source%"=="" goto input_source

set source=%source:"=%

Regarding the section of converting the drive letter from lowercase to uppercase, it is mainly for aesthetic display, and it is also placed as a trick in the script. When I wrote this script, I tried to avoid generating temporary files. Considering that listing more than 20 lines of code for the sake of aesthetics is obviously a bit bloated, this section will be removed in the next version.

Thanks to the moderator for the typesetting. Since there is no 4:3 monitor, I will use the moderator's 78-character width format.

I was just about to release the final version, but then I tested several situations and found that there are still difficult problems in checking the path input. It seems I have to wait until after I finish Children's Day to release the final version :)

The specific problem is:

In the following code, when the path has double quotes at the front and back and has spaces, the program will directly exit and not achieve the expected purpose. The reason is that "%source%" will split this path into two sections from the space, causing a syntax error. And if the statement to judge whether the input is blank is placed after the statement to remove the quotes at the front and back of the path, then when the input is empty, it will also directly exit the program. Hehe, it seems to be another dilemma.

set source=

set /p source=           Please enter the path of the file to be backed up:

if "%source%"=="" goto input_source

set source=%source:"=%

The same problem exists in the section of entering the save path.

I don't know how to solve it.

Hehe, once the boss comes into play, many omissions are picked out, and I'm really grateful.

You said: "There are three lines of code in the :build_batch segment that are wrapped", but I can't detect this on my computer. Could it be caused by wide screens again?

The inconsistency of function keys is indeed a problem, and I'm worrying about it. Before unifying them, I'll make do with it :). Just now, I didn't notice that using 1 as the return to the previous step would cause not being able to backup on the 1st of each month, and I'll change it immediately.

To add a key value under the registry Run, a selection interface needs to be made. Users can give up the function of starting automatically at boot. Then, when stopping a backup task, automatically detect whether the backup task program is still running in at. If it's not running, then delete the backup task program in system32 and the corresponding key value under registry Run. This part of the code will be written in version 6.1. This is also the reason why I have been posting for help these past two days. It has taken up quite a lot of space and is getting close to spamming :). I plan to solve the several problems mentioned in post 34 and the moderator and release it as V1.8. It's estimated that reaching version V1.8 will be quite a success :) Therefore, V1.7 won't be updated for now.

When using the xcopy command to copy folder A, what parameters need to be added to recreate folder A in the new directory and maintain its file structure? I don't know yet. I wonder if the moderator can provide it. Otherwise, I can only prompt users to create a path with the same name as folder A when entering the path in the file saving interface.

Regarding the saving path of %batch_directory%, at first, only the concealment of the saving location was considered (few people would touch the programs in %systemroot%\system32), to avoid being mistakenly deleted and causing backup errors, but the security of the system wasn't considered. It seems that %APPDATA%\%~n0 is a good choice.

Also, it seems that only a few moderators are paying attention to this post, and moderators have numerous tasks and don't have much time to test, resulting in not realizing where their scripts have errors. I've been working on this script alone for half a month. Without everyone's feedback, first, I can't find errors, second, countless tests are tiring, third, the initial passion is gone, and it won't be interesting to continue. Maybe I'll make a final version, then compile it into.exe format, upload it to the forum and then disappear. Hehe, just some grievances.

Re namejm:

Brother, you probably noticed that the title of this thread is highlighted with a red underline in the topic list, which indicates that it has the potential to become an and topic. What's lacking is further improvement, so I hope you can continue to work hard.

The quote issue has been discussed in . For the situation you encountered, you can consider using the solutions from 2-7 in .

The line-wrapping code can be observed in the top post. There are three places where an empty line appears after >>"% .

For the usage of xcopy with a directory name, you can refer to (untested)
for %%p in ("%source%") do set destination=%destination%\%%~nxp
xcopy /d /e /g /h /i /q /x /y "%source%" "%destination%"

How to remove quotes from user-passed parameters?

Get variable witout quotes

set "source=%source:"=%"

The following code still has an error when the input is empty. It's very late, my eyes are heavy. I'll take a good look at the article about removing quotes when I get up in the morning, hoping to perfectly solve my problem.

Re namejm:

The situation where the variable is empty was indeed not noticed, but for this program, the code in the appendix can be used.

In addition, the poor typesetting effect of inserting spaces is because the space width of the default font on the page is only 1/3 of that of Chinese characters. Six spaces are needed to indent two Chinese characters. However, spaces after the post header and , and other codes will be removed. Therefore, when I post, I will use To/Re words at the post header, and try to transfer all quotes and codes to the end of the post.

Another solution is to use two full-width spaces, so that no matter what font the page uses, there will always be an indent of two Chinese characters in any position. But just to enter half-width English, it is necessary to frequently switch between Shift+Space.

set /p source=           Please enter the path of the file to be backed up:

re willsort:

　　It turns out to be a difference between full-width and half-width characters. Let's test by replying to a post :P
　　In the following code, I also thought before that I should add a special symbol in front of the %source% string to mark it, and then test whether this special symbol exactly matches the input in the if statement to solve it, but I never thought to make changes on the set source= line, which led to the attempt to fail.
　　Just came back and saw the moderator's code, so excited. Finally solved a key problem!

 xcopy带目录名的用法，可以参考（未经测试）

         for %%p in ("%source%") do set destination=%destination%\%%~nxp

         xcopy /d /e /g /h /i /q /x /y "%source%" "%destination%"

Rn willsort:

　　

　　The following code, when copying a folder, indeed maintains the original folder's file structure. However, if what is being copied is a file rather than a folder, it will create a folder named "file name.file extension", and there will be only that single file in that folder, which actually increases the number of file layers.

　　Preliminary ideas for solving this problem:

　　When saving the path, prompt the user to make such a choice: if backing up a folder, require entering a path the same as the folder name; if it is a single file rather than a folder, directly enter any path.

　　But doing this will invisibly increase the manual workload of entering the path.

The usage of xcopy with directory names can be referred to (untested)

         for %%p in ("%source%") do set destination=%destination%\%%~nxp

         xcopy /d /e /g /h /i /q /x /y "%source%" "%destination%"

Re namejm:

Handing over the judgment of files and folders to the user is indeed not a good choice, we can judge by ourselves.

for /d %%p in ("%source%.*") do set destination=%destination%\%%~nxp
xcopy /d /e /g /h /i /q /x /y "%source%" "%destination%"

Rn willsort:

　　I see that the boss often uses the for statement, and often a few sentences can solve very complex problems easily. I admire it a lot, and at the same time, I feel the power of the for statement. I really should study the usage of for carefully.

　　Comparing the xcopy statement written by the boss xcopy /d /e /g /h /i /q /x /y "%source%" "%destination%" with the one I wrote myself xcopy /d /h /i /q /s /y "%source%" "%destination%", there are several different parameters. The boss's has /e /g /x more, and discards /s, inheriting file audit settings, empty folders, etc. It can be called a real backup. It seems I didn't think carefully before, and I need to change the parameters.

　　However, I personally think that copying empty directories is of little significance. I don't know what reason the boss has to discard /s and use /e.

Re namejm:

The purpose of using /e is still to keep the backup structure as complete as possible. In any case, this is the responsibility of all backup programs. At the same time, whether a directory is an empty directory cannot be used as the basis for whether it has backup value. In many cases, empty directories can play an identifying role, so it is useful to back them up.

Currently, we are considering whether to enable the cmd auto-completion function to assist in the path input of et /p. Because auto-completion is off by default, and the method to turn it on requires using cmd /f:on, which will create a new CMD instance and may bring some additional impacts. You can try it first.

Re: Regarding Enabling Auto-Completion for File and Directory Names
　　Here's what the book says about enabling the auto-completion function for file and directory names:
　　"By setting the following REG-DWORD values, you can enable or disable the file and directory name completion for all cmd command processing on the computer or in the user session:
　　HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\CompletionChar\REG_DWORD
　　HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\PathCompletionChar\REG_DWORD
　　HKEY_CURRENT_USER\Software\Microsoft\Command Processor\CompletionChar\REG_DWORD
　　HKEY_CURRENT_USER\Software\Microsoft\Command Processor\PathCompletionChar\REG_DWORD
　　To set the RE_DWORD value, you should run Regedit.exe and use the hexadecimal value of the specific control character (for example, use 0x9 for the TAB key and 0x8 for the BACKSPACE key). User-specific settings take precedence over computer settings, and command-line options take precedence over registry settings."
　　I'm currently a registry novice, and I don't understand at all how to represent control characters with hexadecimal values. I'm also unable to act on the moderator's suggestion of "try it out first," and I'm eagerly looking forward to the moderator giving an example.

The control keys for automatic completion are already default settings in the registry. Ctrl+D is for directory completion, and Ctrl+F is for file completion. We can just use cmd /f:on directly. Here is a simple example.
