break /? says:
If Command Extensions are enabled, and running on the Windows platform, then the BREAK command will enter a hard coded breakpoint if being debugged by a debugger.cmd /? says:
Command Extensions are enabled by default. (I learned that we can manually enable/disable by cmd /E:ON/OFF)
Since Command Extensions are enabled by default, then
休息/？说：如果启用了Command Extensions并在Windows平台上运行，那么BREAK命令将在调试器调试时输入硬编码断点。 cmd /？说：默认情况下启用命令扩展。 （我了解到我们可以通过cmd / E手动启用/禁用：ON / OFF）由于默认情况下启用了Command Extensions，
for /f "tokens=*" %%f in (textfile.txt) do (
echo %%f
break
)
should work, but unfortunately not.
Why it's not working? What is the proper way to use break to set a breakpoint in the for loop?
Thanks in advance.
应该工作，但不幸的是没有。为什么它不起作用？使用break在for循环中设置断点的正确方法是什么？提前致谢。

You're not debugging it so naturally nothing happens. More info: breakpoint definition.
To exit from a loop use goto to an outside label:
你没有调试它，所以没有任何反应。更多信息：断点定义。要退出循环，请使用goto到外部标签：
for /f "tokens=*" %%f in (textfile.txt) do (
echo %%f
goto break
)
:break
