WMIC输出到文件而没有其他行问题 [英] wmic output to file without addtional line issue

问题描述

我已经查看了所有这些主题和帖子:

I've looked at all these threads and posts:

线程: https://superuser.com/questions/1082530/如何删除我的Wmic命令的最后空白行

线程:如何从wmic输出中删除空行?

帖子: https://stackoverflow.com/a/37725658/8262102

到目前为止，没有任何帮助，其中大多数使用 findstr/r/v"^ $" 来完成.

So far and none help and most of them use findstr /r /v "^$" to do this.

与它们有关的所有问题是，就我而言，当写入文件时，输出包含额外的一行.

The issue with them all is that in my case the output contains an additional line when written to a file.

我想要的文件输出应该是:

My desired output to file should be:

[Microsoft Windows 10 Pro]

但是我得到了:

[Microsoft Windows 10 Pro
]

这是我的代码，它将在您的桌面上创建输出文件:

Here's my code which will create the output file on your desktop:

@echo off
Setlocal EnableDelayedExpansion
cd /d "C:\Users\%username%\Desktop"
(
  for /f "skip=1 delims=" %%A in (
    'wmic OS get Caption ^| findstr /r /v "^$"'
    ) do echo [%%A]
  )>output.txt && exit

任何帮助将不胜感激.

推荐答案

最简单的解决方案是更改 wmic :

The simplest solution is to change the output format of wmic:

    For /F Tokens^=6Delims^=^" %%A In (
        '"%__AppDir__%wbem\WMIC.exe" OS Get Caption /Format:MOF'
    ) Do Echo [%%A]

上面的答案对于所问的问题是有效的，该问题从一个特定值返回字符串结果.根据您的其他信息，它不再有效，但这不是代码的错误，而是由于您无法提出正确的问题.

对于您要查找的特定值，它们是 Manufacturer ， Name ， Description ， CurrentClockSpeed ， NumberOfCores 和 NumberOfLogicalProcessors ，我会建议使用一种完全不同的方法，即使用 powershell :

For the specific values you were looking for, which were Manufacturer, Name, Description, CurrentClockSpeed, NumberOfCores, and NumberOfLogicalProcessors, I would have suggested a completely different approach, using powershell:

$c = GCIM "Win32_Processor"
$o = ForEach ($i in $c) {
    "Manufacturer:                 " + $i.Manufacturer
    "Name:                         " + $i.Name
    "Description:                  " + $i.Description
    "Current Clock Speed:          " + $([Math]::Round($i.CurrentClockSpeed/1000,2)) + " GHz"
    "Number Of Cores:              " + $i.NumberOfCores
    "Number Of Logical Processors: " + $i.NumberOfLogicalProcessors
}
$o | Out-File ".\CPUInfo.txt"

为了通过批处理文件标签，这是完整的

In order to keep that on topic with the batch-file tag, here's a complete batch-file which leverages powershell:

@"%__AppDir__%WindowsPowerShell\v1.0\powershell.exe" -NoP ^
  "$c = GCIM 'Win32_Processor';" ^
  "$o = ForEach ($i in $c) {" ^
    "\"Manufacturer:                 \" + $i.Manufacturer;" ^
    "\"Name:                         \" + $i.Name;" ^
    "\"Description:                  \" + $i.Description;" ^
    "\"Current Clock Speed:          \" + $([Math]::Round($i.CurrentClockSpeed/1000,2)) + \" GHz\";" ^
    "\"Number Of Cores:              \" + $i.NumberOfCores;" ^
    "\"Number Of Logical Processors: \" + $i.NumberOfLogicalProcessors};" ^
  "$o | Out-File \".\CPUInfo.txt\""
