好像写得有点繁，呵呵。
问个问题：批处理中有对文本进行进行换行的常量吗？如VB中有vbcrlf。

答：

 @echo off
setlocal enabledelayedexpansion
echo =======替换版==========
for /f %%a in (a.txt) do (
   set a=%%a
   set a=!a:他娘的=TND!
   echo !a!
)
echo.
echo =======去除版==========
for /f %%a in (a.txt) do (
   set a=%%a
   set a=!a:他娘的=!
   echo !a!
)
pause>nul
复制代码

效果：


======================
end;

solid

@echo off
SETLOCAL ENABLEDELAYEDEXPANSION
for /f "tokens=*" %%a in ( a.txt ) do (
set ti1=%%a
set "ti=!ti1:他娘的=TND!"
echo !ti! >>b.txt
)
del a.txt
ren b.txt a.txt
for /f "tokens=*" %%a in ( a.txt ) do (
set ti1=%%a
set "ti=!ti1:TND=!"
echo !ti! >>b.txt
)
del a.txt
ren b.txt a.txt

    set "s2=!s1:TND=!"   
)
echo !s1!
echo !s2!
pause>nul

有点遗憾是没能实现换行显示！还请各位前辈赐教。。。

不过原理不是很清楚只是依葫芦画瓢，所以希望知道原理的前辈给晚辈详细讲解一番，晚辈在此先谢过了。。。
