批处理如何循环读取txt文件

123rt

代码如下

1. for /f "delims= " %%i in (z.txt) do del %%i.bat
   
2. for /f "delims= " %%i in (z.txt) do echo goto start>>%%i.bat
   
3. for /f "delims= " %%i in (z.txt) do echo :start>>%%i.bat
   
4. for /f "delims= " %%i in (z.txt) do echo a.exe %%i %%i.bat
   
5. for /f "delims= " %%i in (z.txt) do echo if errorlevel 1 goto exit>>%%i.bat
   
6. for /f "delims= " %%i in (z.txt) do echo if errorlevel 0 goto d>>%%i.bat
   
7. for /f "delims= " %%i in (z.txt) do echo :d>>%%i.bat
   
8. for /f "delims= " %%i in (z.txt) do echo (echo %%i^>^>a.txt)>>%%i.bat
   
9. for /f "delims= " %%i in (z.txt) do echo goto exit>>%%i.bat
   
10. for /f "delims= " %%i in (z.txt) do echo :exit>>%%i.bat
    
11. for /f "delims= " %%i in (z.txt) do echo exit>>%%i.bat
    
12. for /f "delims= " %%i in (z.txt) do start %%i.bat
    
13. exit

从z.txt中读取参数给a.exe，把成功的结果输出到a.txt中，现在问题是，z.txt中有几千行的参数，那么运行后，就会产生几千个bat，怎么能设定一次读取100个，完成后继续往下执行，知道读取全部z.txt中的参数，请各位大虾们指教！

由于你要判断a.exe的结果再输出.所以我觉得用两个批好点
第一个,实现每次100个输出,保存任意名字.

1. @echo off
   
2. setlocal enabledelayedexpansion
   
3. set n=0
   
4. 
   
5. for /f "delims=" %%a in (z.txt) do (
   
6. if /i "!n!" neq "100" (
   
7. start "" "a.bat" "%%a"
   
8. set /a n=n+1
   
9. ) else (
   
10. "a.exe" "%%a"
    
11. if /i "%errorlevel%" equ "0" (
    
12. echo %%a >> "a.txt"
    
13. )
    
14. set n=0
    
15. )
    
16. )

复制代码

第二个保存为a.bat,

1. @echo off
   
2. cd /d "%~dp0"
   
3. a.exe %1
   
4. if /i "%errorlevel%" equ "0" (
   
5. echo %1 >> a.txt
   
6. )

复制代码

这种方法我没有实测过.~~估计有问题.~~哈哈,可以当做参考.~
