Question

我正在尝试编写Get-foldersize函数，但我无法安排完整的输出。最后是圆点。

以下是脚本详细信息。

Function Get-FolderSize 
{

[CmdletBinding(DefaultParameterSetName='FolderPath')]
param 
(
[Parameter(Mandatory=$true,Position=0,ParameterSetName='FolderPath')]
[String[]]$FolderPath,
[Parameter(Mandatory=$false,Position=1,ParameterSetName='FolderPath')]
[String]$graterthan,
[Parameter(Mandatory=$false,Position=2,ParameterSetName='FolderPath')]
[switch]$Recurse

)
Begin 
{
#$graterthan and $ZeroSizeFolders cannot be used together
#Convert the size specified by Greaterhan parameter to Bytes
$size = 1000000000 * $graterthan

}

Process {#Check whether user has access to the folders.


        Try {
        Write-Host "Performing initial tasks, please wait... " -ForegroundColor Magenta
        $subfolders = If ($Recurse) {Get-ChildItem $FolderPath -Recurse -ErrorAction SilentlyContinue } 
        Else {Get-ChildItem $FolderPath -ErrorAction SilentlyContinue } 

        } 
        Catch [exception]{}

        #Calculate folder size
        If ($subfolders) 
        {
        Write-Host "Calculating size of folders in $FolderPath. This may take sometime, please wait... " -ForegroundColor Magenta
        $Items = $subfolders | Where-Object {$_.PSIsContainer -eq $TRUE -and `
        @(Get-ChildItem -LiteralPath $_.Fullname -Recurse -ErrorAction SilentlyContinue | Where-Object {!$_.PSIsContainer}).Length -gt '0'}}


        ForEach ($i in $Items)
        {

        $subFolders = 
        If ($graterthan)
        {Get-ChildItem -Path $i.FullName -Recurse | Measure-Object -sum Length | Where-Object {$_.Sum -ge $size -and $_.Sum -gt 1000000 } }
        Else
        {Get-ChildItem -Path $i.FullName -Recurse | Measure-Object -sum Length | Where-Object {$_.Sum -gt 1000000  }}
        #Return only values not equal to 0
        ForEach ($subFolder in $subFolders) {
        #If folder is less than or equal to 1GB, display in MB, If above 1GB, display in GB 
        $si = If (($subFolder.Sum -ge 1000000000)  ) {"{0:N2}" -f ($subFolder.Sum / 1GB) + " GB"} 
        ElseIf (($subFolder.Sum -lt 1000000000)  ) {"{0:N0}" -f ($subFolder.Sum / 1MB) + " MB"} 
        $Object = New-Object psobject -pro @{            
        'Folder Name'    = $i.Name                
        'Size'    =  $si
        'Full Path'    = $i.FullName          
        }
        [array]$space = $Object 
        $Object | Select-Object 'Folder Name', 'Full Path',Size 

} 

}


}
End {

Write-Host "Task completed...if nothing is displayed:
you may not have access to the path specified or 
all folders are less than 1 MB" -ForegroundColor Cyan
}
}

输出：

Name                          Created                **FilePath**                          SizeMB

我正在尝试获取完整的文件路径。甚至我试过out-string -width 300并尝试外包。当我尝试输出字符串时，它显示完整的文件路径，但每次在新输出行之前打印对象。

请有人建议正确的方法来打印完整的文件路径和所有没有点的输出。在此先感谢：）

说实话，这不是你担心的。数据不会丢失，只是为了显示目的而被截断。

public void capture(View v){
captureImage();
}

当你直接看房子时，就在那里。

最终用户将决定何时查看完整输出，或根据需要对其进行格式化：

$data = Get-FolderSize
$data.FilePath

如果您真的希望特别显示命令的输出，可以create a custom format specification，但这也需要您创建一个新类型以应用该格式。

对于你的例子，我真的不认为这是值得的。使用PowerShell的人倾向于快速习惯返回对象的想法，以及如何使用和操纵这些对象进行显示。

不要在你的功能中使用$data | Format-Table -AutoSize $data | Format-List;通过这样做，您正在销毁原始对象并将输出转换为纯文本。
