试试这个：

set "myline=if 3 NEQ 2 echo yes"

( %myLin^e%)|sort

或来自批处理文件（双重扩展与批处理文件和控制台的工作方式不同）：

or from batch file (double expansion works differently from batch file and the console):

set "myline=if 3 NEQ 2 echo yes"

( %%myLine%%)|sort

神秘由jeb 这里和此处。虽然你在管道之前遇到了这个问题，但它是同一个bug，因为cmd在管道的每一边创建了两个线程。

The "mystery" was solved by jeb here and here . Though you are facing the issue before the pipe it is the same bug because the cmd creates two threads on each side of the pipe.

以下是for循环的制作方法工作：

Here's how the for loop can be made to work:

set "line=if %a NEQ 0"
(for /L %a in (1,1,9) do @( %lin^e% echo %a))|sort /R
