Question

我尝试在网格框中查询磁盘空间信息并将其导出为CSV。

我能够使用Marc Weisel的脚本使其使用不同的凭据。我用过computers.csv

存储计算机名称和引用的凭据。这是有效的，虽然我面临的问题是网格框打开csv中提到的所有服务器。

我想查看同一网格框中的所有磁盘空间信息。

以下是我使用

的脚本和模块

    Import-Module D:\get.psm1
Import-Module D:\out-CSV.psm1
$ComputerList = Import-Csv -Path d:\Computers.csv;
#$servers = 'laptop-pc','laptop-pc','laptop-pc'
$CredentialList = @{
    Cred1 = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList 'laptop-pc\laptop', (ConvertTo-SecureString -String 'tamboli' -AsPlainText -Force);
    #Cred2 = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList 'tnt\administrator', (ConvertTo-SecureString -String 'Atlantic12' -AsPlainText -Force);
    }
foreach ($computer in $ComputerList ) 
{
Get-DiskFree -ComputerName $Computer.Name -Credential $CredentialList[$Computer.Credential] -Format | ? { $_.Type -like '*fixed*' } | select * -ExcludeProperty Type |
}

您需要将Get-DiskFree的结果附加到循环中的数组中，并将结果从循环外部传递给网格视图：

foreach ($computer in $ComputerList ) 
{
    $result += Get-DiskFree -ComputerName $Computer.Name -Credential $CredentialList[$Computer.Credential] -Format | ? { $_.Type -like '*fixed*' } | select * -ExcludeProperty Type 
}

$result | Out-GridView

或者，更好的是，从Foreach-Object循环外部管道结果：

$ComputerList | % {
    Get-DiskFree -ComputerName $_.Name -Credential $CredentialList[$_.Credential] -Format | ? { $_.Type -like '*fixed*' } | select * -ExcludeProperty Type 
} | Out-GridView

使用单独的凭据为不同的服务器获取可用磁盘空间
