Also, please trouble again: Why not add a .* at the end, in the form of ".*\.*", what is the difference between this and not adding it?
...

.*\ just matches if the conditions are met, so it doesn't matter if there is content after the
Adding .* after means it matches whether there is content after the or not.
But if it is ". *\..*", it's different. It means there must be at least one character after the

Oh, that is, .*\[..*\] just needs to meet the conditions to match, I got it, thank you very much. Does for /f not ignore lines starting with ; by default?

Why does the empty line of [ not become empty anymore? It only deletes the ; and all spaces.
@echo off
for /f "delims=:" %%a in ('findstr /n ".*\[..*\]" a.txt') do set .%%a=a
for /f "tokens=1* delims=:" %%a in ('findstr /n .* a.txt') do (
if defined .%%a echo.
for /f "tokens=*" %%i in ("%%b") do echo.%%i>>temp.txt
)

If you add a .* later, then lines like add that don't end with ] will also be matched, and such lines are not what the楼主 wanted, right?


Lucky! There are no such things in the file I modified.

Adding or not adding .* both match [reg]add. Because .* can be nothing, but ..* means there must be at least one character.

Your changes are too many. You solve one and another comes.
Moreover, I can't understand the simplified language above you.

@echo off
for /f "delims=:" %%a in ('findstr /n ".*\" a.txt') do set .%%a=a
for /f "tokens=1* delims=:" %%a in ('findstr /n .* a.txt') do (
if defined .%%a echo.
for /f "tokens=*" %%i in ("%%b") do echo.%%i
)

This code basically already achieves what I said. How to output?
