用于比较两个文件并将输出合并到第三个文件的 PowerShell 脚本
PowerShell script to compare two files and merge the output the into a third file
我有 2 个文件需要与 PowerShell 进行比较，并使用合并输出生成第三个文件，其中包含来自 file1.txt 和 file2.txt.
的所有行
这是 file1.txt 和 file2.txt 的示例：
file1.txt内容

我在论坛里查看过类似的post
但它没有产生我需要的结果。谁能帮忙想个办法。
谢谢。
您可以使用 Group-Object cmdlet 计算出每个名称的主机，然后将新的 属性 添加到 file1 中的每个新对象，并使用 [=13= 加入分组数据].
$file1 = Import-Csv .\file1.csv
$file2 = Import-Csv .\file2.csv
# Group file2 by Name and output as a hashtable
$group2 = $file2 | Select-Object Name, PresentTo | Group-Object -Property Name -AsHashTable
$file1 | ForEach-Object {
# Add the new property (column) 'PresentTo' with the matching file2 Hosts joined by ';'
$_ | Add-Member -NotePropertyName PresentTo -NotePropertyValue ($group2.($_.Name).PresentTo -join ';') -PassThru
} | Export-Csv .\file3.csv
# have a look at our new file
Import-Csv .\file3.csv | Format-Table *
输出
