Question

我遇到一些问题让Windows PowerShell做我想做的事情。基本上，我在当前文件夹中有24个子文件夹，名为Angle1，Angle2等，最高为角度24。

在每个子文件夹中都有一个名为output.txt的文件。在output.txt中，有10列数据，以空格分隔。我想获取每个子文件夹中每个output.txt文件的第9列，并将它们全部放在名为total.txt的父文件夹中的新文件中。所以，最终，我会有24列数据，每列都用空格分隔。 total.txt的第一列对应于Angle1等中output.txt的第9列。

请注意，Angle文件夹包含其他我想忽略的子文件夹。

尽管有很多尝试，但我还是无法让它发挥作用。我不确定是否需要使用-Recurse选项来执行此操作，或者如果Powershell甚至能够执行此操作。这里有没有人是powershell的专家，可以说这是否可能？

除了一个output.txt文件之外的一小部分：

我使用的代码是在Linux中，它在某种程度上起作用：

awk '{print $9}' Angle1/output.txt >>tmp
for ((i=2;i<25;i++))
do
awk '{print $9}' Angle${i}/output.txt |paste -d " " tmp - >>total.txt
mv total.txt tmp
done
mv tmp total.txt

但是，现在我需要在Powershell中运行，而不是linux。目前我还没有任何远程适用于此的代码。基本上是Get-Child命令等的集合，但没有任何接近我想要的东西。

Answer 2

试试这个

            $result = @()
    $Anglecount = 0

    do {
    $Anglecount ++
        $content = get-content (".\Angle"+$i+"\output.txt")
        foreach ($line in $content) { 

            $trimmed = $line.Trim()
            $split = $line.Split(" ")
            $result += $split[8]

        }
        $Anglecount
    } until ($Anglecount -eq 24)

    $result | Out-File total.txt

不是最优雅的解决方案，但会为您解决问题

Answer 3

如果这是逗号分隔输入，这将很简单。所以我创建了一个简短的脚本来将数据转换为CSV，以这种方式保存，然后我展示了如何使用它的简短示例。

function Get-ColumnData { param（[string] $ folder）

$fileInput = Get-Content -Path "$folder\output.txt"

# initialize an array
$fileOutput = @()

# put title headers for later import as CSV
# I chose arbitrary names, they can be almost anything, but avoid spaces and special characters
$fileOutput += "Column1,Column2,Column3,Column4,Column6,Column7,Column8,Column9,ColumnA"

foreach ($line in $fileinput) {
    # here's the meat, trim whitespace off the end and replace spaces with commas
    $line = $line.TrimEnd() -replace ' ',','

    # add the results to the array
    $fileoutput += $line
    }
# write to a csv
# there's proabably another way to go from an array of strings to an array of objects, 
#    but saving as a CSV, then importing the CSV is dirt simple
$fileOutput | out-file 'C:\temp1\converted.csv'
$Objects = import-csv 'C:\temp1\converted.csv'

# Select the next to last column
$Objects | Select -ExpandProperty Column9 
}

    $location = "c:\temp1" #set to whatever local or remote path
    $folders = Get-ChildItem $location -Directory
    foreach ($folder in $folders) {
        if (Test-Path $folder\output.txt) {
            $folderColumn = Get-ColumnData $folder
            }
            # at this point you have a column of data but it's stored as a collection of strings
            # need to do something here to add it to your data file and I'm stuck there
        }

您需要从这里找到一种方法，从$ Objects中获取一列，并将其作为最终答案的列。

使用PowerShell收集某些数据列
