I need it urgently, handling thousands of records is really too hard

Requirement: for lines that exist in A.txt, search through B.txt line by line, and then output the ones not found to 结果.txt

for /f "delims=" %%i in (a.txt) do set "%%i=="

for /f "delims=" %%i in (b.txt) do if not defined %%i >>c.txt echo.%%i

Using a.txt as the sample for comparison, if the same line does not exist in b.txt then output it to c.txt

for /f "delims=" %%i in (a.txt) do set "%%i=="

for /f "delims=" %%i in (b.txt) do if defined %%i >>c.txt echo.%%i

Using a.txt as the sample for comparison, if the same line exists in b.txt then output it to c.txt
