For example, there is a text file with several lines of content, such as:
1,2,3,4
7,8,9,10
……
How to count the number of commas in it?

In fact, I don't have a very good way for this kind of question. I think the limitations are also very big, and I haven't found a good way to solve it. But the landlord can try the following code:
@echo off
setlocal enabledelayedexpansion
set a=
for /f "delims=" %%a in (要检索的文件.txt) do set a=!a!%%a
:back
set /a b+=1
set a=%a:*,=%
if "%a%"=="这里是最后一个逗号后面内容" goto end
goto back
:end
echo There are %b% commas

set a=
for /f "delims=" %%a in (要检索的文件.txt) do set a=!a!%%a

set /a b+=1
set a=%a:*,=%
if "%a%"=="这里是最后一个逗号后面内容" goto end
goto back
:end
echo There are %b% commas

Look at help
set 变量名=%变量:1=2%
This means to replace 1 in front with 2 after =.

Thanks to bagpipe, I can use it with a little modification based on your code.
——The limitation you mentioned should be that the content after the last comma in "if "%a%"=="here is the content after the last comma" goto end" needs to be entered manually, right?

The limitations I mentioned are not what Brother namejm said. In fact, I can get the content after the last comma. The limitation I mentioned is because you assign all the characters in the file to a variable, and then how many characters this variable can bear at most. If there is no content after the last comma, this situation will not be the case.
