Question

我想这样做：

@echo off
for %%x in (0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F) do (
    ctext.exe {07} %%x
)
echo.
for %%y in (0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F) do (
    ctext.exe {07}%%y
    for %%x in (0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F) do (
    ctext.exe {%%x%%y}%%x%%y
    )
    echo.
)
pause>nul
exit /b

进入一行，但如何在for循环后获取命令？

@echo off && for %%x in (0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F) do ( ctext.exe {07} %%x ) <-- Here -->

我无法使用&&，因为它在for循环中使用它。

Answer 1

&&和||相当于基于上一个命令的错误级别的条件的then else部分。以下是

echo "test" | find "is" > nul
if errorlevel 1 (
    echo not found
) else (
    echo found
)

可以写成

echo "test" | find "is" >nul && echo found || echo not found

连接命令所需的是&并放置一些括号以确保命令的分离

(for in () do ( a & b )) & (for in () do ( b & c ))

批处理文件一行编码（for loops）
