到目前为止，var 测试没有给我输出该行的第一个字符

cls
@echo off

SET sourcefile=sourcefile.txt

for /F "tokens=*" %%A in (%sourcefile%) do (

    for /F "tokens=*" %%B in (%%A) do (
        SET leadingLetter= %%B:~0,1%
        echo %leadingLetter%

    )

)

您说您正在处理完整的行，所以这将满足您的要求。

@echo off
find "-" <filein.txt >negative.txt
find /v "-" <filein.txt >positive.txt
