如何使用powershell將文本檔案作為列添加到現有csv？

2022-06-14 02:36:06 區塊鏈

我發現了很多類似這樣的問題，這些問題解釋了如何添加在整個 csv 中重復的具有相同值的列。

我所擁有的有點不同。我有 randlist.txt，它看起來像這樣：

24830
4557
30795
19711
15481
42181
17331
32468
39411
30067
5124
35030
17776

有超過 40,000 個值。與此 allpeeps.csv 檔案中的行數相同，如下所示

到目前為止我最接近的是

$rands = Get-Content ./randlist.txt;$People = ./allpeeps.csv;$csv = @();for ($i = 0; $i -lt $rands.Count; $i  ){$row = "" | Select rands,People;$row.rands = $rands[$i];$row.People = $People[$i];$csv  = $row};$csv | Export-Csv ./newpeeps.csv -NoTypeInformation

但是，這會導致 csv 包含 2 列 - 一個看起來正確的“rand”，另一列稱為人員，并且所有資訊都集中在一個列中。我怎樣才能將此列添加到 csv？

uj5u.com熱心網友回復：

這可能會奏效，因為無需對現有 Csv 進行任何修改，您可以將其視為簡單的文本檔案，只需在新檔案 ( randlist.txt) 的行前加上逗號即可。

# the comma before `rand` is important, don't remove it!
$newData = , 'rand'   (Get-Content .\randlist.txt -ReadCount 0)
$csv = Get-Content .\allpeeps.csv -ReadCount 0

& {
    for($i = 0; $i -lt [math]::Max($newData.Count, $csv.Count); $i  ) {
        # `$csv[$i].TrimStart('"')` if you need to remove the leading double-quote
        $newData[$i]   ','   $csv[$i]
    }
} | Set-Content .\newData.csv # Use a test file here before replacing the original Csv
