[文本处理] 批处理如何查找到文本中含有指定字符串时在该行后面加上特定字符串？

welky

如c:\test.txt文件中有如下内容:

"我爱BAT!"
call c:\test\test.bat
echo copy finished!

想找到以"call"开头的行后面加上字符串" -- -p test.class"
完成后应该如下：
"我爱BAT!"
call c:\test\test.bat -- -p test.class
echo copy finished!

请问该怎么实现？
谢谢

@echo off
for /f "delims=" %%a in ('findstr /b "call" a.txt') do set %%a=a
for /f "delims=" %%a in (a.txt) do (
   if not defined %%a (echo %%a) else echo %%a -- -p test.class
)
pause

echo.%%i|findstr/i ^call.*$ >nul 2>nul&&echo %%i-- -p test.class>>_test.txt||echo %%i>>_test.txt
)
