通过批处理文件删除WMIC结果中不需要的空格 [英] Remove unwanted spaces in wmic results through batch file

问题描述

我正在处理一个批处理文件，其中我需要显示电池的剩余电量，我已经实现了我的目标，但是由于命令结果中存在多余和多余的空格，我对结果不满意.

Im working on a batch file in which I need to show the estimated charge remaining of the battery, I have achieved my goal but sadly I am not happy with the results due to excesive and unwanted spaces in the command result.

这是我的代码:

:charge
FOR /F "delims= skip=1" %%i IN ('WMIC PATH Win32_Battery Get EstimatedChargeRemaining') DO ( SET CHR=%%i
GOTO results )

:results
ECHO "Battery Percentage: %CHR%"
PAUSE
GOTO menu

以上命令的结果为:电池百分比:100"

如何在结果末尾去除那些空格?

How do I get rid of those spaces at the end of the result?

预先感谢，非常感谢您提供任何帮助.

Thanks in advance and any kind of help is greatly appreciated.

推荐答案

尝试如下:

:charge
@echo off
FOR /F "tokens=* delims=" %%i IN ('WMIC PATH Win32_Battery Get EstimatedChargeRemaining /format:value') DO (
    for /f "tokens=* delims=" %%# in ("%%i") do set "%%#"
)
echo %EstimatedChargeRemaining%

WMIC添加了其他字符，但可以使用一个for循环将其删除-> https://www.dostips.com/forum/viewtopic.php?t=4266

WMIC adds additional character but it can be removed with one more for loop -> https://www.dostips.com/forum/viewtopic.php?t=4266
