批处理 for循环[通俗易懂]

@echo off
for /d %%i in ("c:\*.*") do @echo %%i
pause

@echo off
cd "C:\Program Files"
for /d %%i in (??????) do @echo %%i
pause

@echo off  
rem for的 递归执行
cd "C:\Program Files"
for /r  %%i in (*.exe) do @echo %%i
rem for /r c:/ %%i in (*.exe) do @echo %%i 显示C盘下所有的exe
pause

::显示C:\Program Files目录下的所有exe

@echo off
for /l %%i in (1,1,5) do @echo %%i
pause

@echo off
for /f %%i in (a.txt) do echo %%i
pause

@echo off
for /f "tokens=2,3 delims= " %%i in (a.txt) do echo %%i %%j
pause

rem 设置tokens=2,3 这样只读取每一行中的第二个和第三个元素

@echo off
for /f "tokens=* delims= " %%i in (a.txt) do echo %%i
pause

rem 设置tokens=* 这样读取每一行的内容

@echo off
for /f "tokens=2,* delims= " %%i in (a.txt) do echo %%i %%j
pause

rem 设置tokens=2,* 这样读取每一行第二列和后面的元素

@echo off
for /f "skip=2 tokens=*" %%i in (a.txt) do echo %%i
pause

@echo off
for /f "eol=. tokens=*" %%i in (a2.txt) do echo %%i
pause

rem 忽略以“.”开头的行

@echo off
for /f "skip=1 delims=" %%i in (a.txt) do echo %%i
pause

rem 难道delims设置为空时，默认是回车么？？？

for /f tokens^=1^,2^ delims^=^" %%a in (a.txt) do echo %%a %%b
    pause
