 『楼 主』:
去掉文件名称前的特定字符
使用 LLM 解释/回答一下
这个是我在GOOGLE组上看到的，顺便发到这里供大家学习，虽然局限性很大，不过可以看看。
主要是去掉文件名前的0
处理前：
0000001.txt 00000010.txt 00000011.txt
00000012.txt 00000013.txt 00000014.txt 00000015.txt 00000016.txt
00000017.txt 00000018.txt 00000019.txt 0000002.txt 00000020.txt
0000003.txt 0000004.txt 0000005.txt 0000006.txt 0000007.txt
0000008.txt 0000009.txt
处理后：
1.txt 10.txt 11.txt 12.txt 13.txt
14.txt 15.txt 16.txt 17.txt 18.txt 19.txt 2.txt
20.txt 3.txt 4.txt 5.txt 6.txt 7.txt 8.txt
9.txt
@echo off
for /f "delims=" %%a in ('dir/b *.txt') do call :next %%a
echo Finish...
goto :eof
:next
set pp=%1
:loop
if %pp:~0,1%==0 set pp=%pp:~1%& goto :loop
ren %1 %pp%
This is what I saw on the GOOGLE group, and I sent it here for everyone to study. Although it has great limitations, you can take a look.
Mainly to remove the 0 before the file name
Before processing:
0000001.txt 00000010.txt 00000011.txt
00000012.txt 00000013.txt 00000014.txt 00000015.txt 00000016.txt
00000017.txt 00000018.txt 00000019.txt 0000002.txt 00000020.txt
0000003.txt 0000004.txt 0000005.txt 0000006.txt 0000007.txt
0000008.txt 0000009.txt
After processing:
1.txt 10.txt 11.txt 12.txt 13.txt
14.txt 15.txt 16.txt 17.txt 18.txt 19.txt 2.txt
20.txt 3.txt 4.txt 5.txt 6.txt 7.txt 8.txt
9.txt
@echo off
for /f "delims=" %%a in ('dir/b *.txt') do call :next %%a
echo Finish...
goto :eof
:next
set pp=%1
:loop
if %pp:~0,1%==0 set pp=%pp:~1%& goto :loop
ren %1 %pp%

如果名字纯粹是楼主所示（类型），貌似还可以利用数字的特性来处理开头的"00....."简化代码：
@echo off
for /f "delims=" %%i in ('dir/b *.txt') do (
echo 正在处理.......
set /a name=%%~ni+0
call ren "%%i" "%%name%%%%~xi"
)
echo 处理完毕
pause
If the name is purely as shown by the owner (type), it seems that the characteristics of numbers can be used to handle the leading "00....." to simplify the code:
@echo off
for /f "delims=" %%i in ('dir/b *.txt') do (
echo Processing.......
set /a name=%%~ni+0
call ren "%%i" "%%name%%%%~xi"
)
echo Processing completed
pause

欣赏youxi01兄非常巧妙的方法～：）
太巧合啦，SET /A 居然把这么多的０前缀的 00000020 当成了以0开头的８进制数字了，结果８进制的20正好是10进制的16～：）
C:\TEMP\file>set /a 00000020
16
意外的是那个 00000020.txt 被 SET /A 由 SET认为的８进制转成了１０进制的 16.txt 了～：）
不过这只是意外：）
欣赏youxi01兄好玩的实现方法～：）
Appreciate brother youxi01's very clever method~ :)
It's too coincidental that SET /A actually treats so many 0-prefixed 00000020 as octal numbers starting with 0. As a result, octal 20 is exactly 16 in decimal~ :)
C:\TEMP\file>set /a 00000020
16
The unexpected thing is that the 00000020.txt was converted by SET /A from the octal number that SET thought into 16.txt in decimal~ :)
But this is just an accident~ :)
Appreciate brother youxi01's fun implementation method~ :)

『第 8 楼』:
使用 LLM 解释/回答一下
set /a 的方法要么受进制的影响容易出错，要么就是难以得知首位0的个数从而不易通过在首位添1再减的方式来求出结果，还是通过探测首位是否为0来决定是否继续抛弃首位的一个0这种方法比较具备通用性。
The method of set /a is either affected by the number system and prone to errors, or it is difficult to know the number of leading zeros, so it is not easy to find the result by adding 1 at the leading position and then subtracting. Still, the method of detecting whether the leading digit is 0 to decide whether to continue to discard one leading 0 is more universal.

不好意思，忘记了进制的问题，自己比较粗心（冲动）的性格还是没有改变啊！namejm的说法不错，不过这个问题也不是没有解决的，看看下面的代码还存在什么的问题（解决了进制的问题）：
@echo off & echo 正在处理.......
for /f "delims=" %%i in ('dir/b *.txt') do (
set /a name=2%%~ni-1%%~ni
call set /a name=1%%~ni-%%name%%
call rename "%%i" "%%name%%%%~xi"
)
echo 处理完毕
pause
I'm sorry, I forgot about the issue of number bases. My careless (impulsive) personality still hasn't changed! namejm's statement is good, but this problem isn't without a solution. Let's see what other problems there are in the following code (after solving the number base issue):
@echo off & echo Processing.......
for /f "delims=" %%i in ('dir/b *.txt') do (
set /a name=2%%~ni-1%%~ni
call set /a name=1%%~ni-%%name%%
call rename "%%i" "%%name%%%%~xi"
)
echo Processing completed
pause

这种取位循环去零法的确很爽, 通用各种情况. 在批处理处理浮点数中也屡试不爽.

This method of taking digits in a loop to remove zeros is indeed very cool, and it works well in various situations. It has also worked well in dealing with floating-point numbers in batch processing.
Regarding the problem of octal errors, there has been a discussion before.
