As the title says, suppose text file 123.txt contains characters like the following
yiqiweiaoyunjiayou



]end title



abc
abcdef
I want to find the lines that start with and display them



The code findstr "^$" is not right. How should it be modified? Thanks!

findstr /r "^\$" 123.txt

In the FINDSTR command, are metacharacters in regular expressions, so you must use \ to escape them into literal characters

Thanks to the poster above.

If the last line is just , rather than a blank line after it, then will not be displayed.

I agree with the poster above

Why can't it display the last line [12345]?

Don't just talk about my code, look at what your own code is saying too

As long as your last line has a carriage return and line feed, my code is enough

Thanks, but it still feels like if I tweak it just a tiny bit more it would be perfect! Indeed, sometimes there is no newline at the end.
Brother s11ss's code is fine, but it would be best if something like "findstr "^\$" 123.txt" could be used.

This line shouldn't be displayed in the first place, since it doesn't start with

Sigh, the key point is that it does display it

findstr ^$

It really is a bit wrong. I didn't notice this point at first either. If there are characters before

If there's no carriage return line, then forcibly add one. I do that sometimes.

Before processing 123.txt, no matter whether its last line has a carriage return or not, first execute the following code:

echo. >>123.txt
