尝试连续报告CPU时钟速度 [英] Attempting to report CPU clock speed continuously in batch

问题描述

我正在尝试制作CPU时钟速度跟踪器，但是我需要一些有关代码的帮助.

I am trying to make a CPU clock speed tracker, but I need some help on the code.

setlocal enableextensions enabledelayedexpansion
:a
for /f %%a in ('copy /Z "%~dpf0" nul') do set "ASCII_13=%%a"
set /p "=!ASCII_13!" <NUL
wmic cpu get CurrentClockSpeed
goto a

我有兴趣得到这样的东西:

I'm interested in getting something like this:

CurrentClockSpeed
2401

不是这个(我尝试使用的代码输出这个):

not this (the code I'm trying to use outputs this):

CurrentClockSpeed
2401


CurrentClockSpeed
2401


CurrentClockSpeed
2401


CurrentClockSpeed
2401

你能帮我吗?

推荐答案

wmic的行尾很丑陋(另外一个CR)，经常会引起麻烦.就您而言，它可以为您完成工作:

wmic has an ugly line ending (an additional CR), that regularily makes trouble. In your case, it does the work for you:

@echo off
setlocal EnableDelayedExpansion
:loop
for /f "delims=" %%a in ('wmic cpu get LoadPercentage /value ^|find "="') do (
  set "value=%%a"
  <nul set /p "=!value:~0,-1!  !value:~-1!"
)
goto :loop

您应该将wmic输出过滤到一行(wmic也返回一些空行)
(我选择了另一个值(LoadPercentage)来使事情发生)

You should filter wmic output to one line (wmic returns some empty lines too)
(I choosed another value (LoadPercentage) to let something happen)

我将值(包括附加的CR)分配给变量，然后将[variable minus CR]写入三个空格和[value的最后一个字符](即CR). 当新值比旧值短时，必须用三个空格覆盖其余字符.

I assign the value (including the additional CR) to a variable, then write [variable minus CR] three spaces and the [last char of value] (which is the CR). The three spaces are neccessary to overwrite remaining characters, when the new value is shorter than the old one.
