我有一个powershell脚本,它获取文件夹Name,LastWriteTime,Size
cd \myfolder
get-childitem | where {$_.PSIsContainer} | foreach {
$size = ( Get-ChildItem $_ -Recurse -Force | where {!$_.PSIsContainer} | Measure-Object -Sum Length).Sum
$obj = new-object psobject
add-member -inp $obj noteproperty path $_.Name
add-member -inp $obj noteproperty time $_.LastWriteTime
add-member -inp $obj noteproperty size $size
$obj
}
导致路径/名称,LastWriteTime,大小
path time size

我想修改结果以添加以下功能
要添加自动转换功能,我在某个论坛找到了以下内容
# If ( $size -lt 1KB ) { $sizeOutput = "$("{0:N2}" -f $size) B" }
#ElseIf ( $size -lt 1MB ) { $sizeOutput = "$("{0:N2}" -f ($size / 1KB)) KB" }
#ElseIf ( $size -lt 1GB ) { $sizeOutput = "$("{0:N2}" -f ($size / 1MB)) MB" }
#ElseIf ( $size -lt 1TB ) { $sizeOutput = "$("{0:N2}" -f ($size / 1GB)) GB" }
#ElseIf ( $size -lt 1PB ) { $sizeOutput = "$("{0:N2}" -f ($size / 1TB)) TB" }
#ElseIf ( $size -ge 1PB ) { $sizeOutput = "$("{0:N2}" -f ($size / 1PB)) PB" }
#Write-Output $sizeOutput
但是由于我对这个脚本问题缺乏了解,如何将其与现有脚本合并并得到我想要的 结果...... 任何帮助都会非常感激......
答案 0 :(得分:4)
您可以将逻辑放在ex中。一个可重用的函数,用于生成size
的属性值。在这个解决方案中,我使用了计算属性而不是函数。这样我们就可以保留原始大小(长度之和)进行排序,然后修改输出。我还简化了你的对象创建。例如:
GET-FoldersWithSize.ps1:
param ($Path = ".")
$PrettySizeColumn = @{name="Size";expression={
$size = $_.Size
if ( $size -lt 1KB ) { $sizeOutput = "$("{0:N2}" -f $size) B" }
ElseIf ( $size -lt 1MB ) { $sizeOutput = "$("{0:N2}" -f ($size / 1KB)) KB" }
ElseIf ( $size -lt 1GB ) { $sizeOutput = "$("{0:N2}" -f ($size / 1MB)) MB" }
ElseIf ( $size -lt 1TB ) { $sizeOutput = "$("{0:N2}" -f ($size / 1GB)) GB" }
ElseIf ( $size -lt 1PB ) { $sizeOutput = "$("{0:N2}" -f ($size / 1TB)) TB" }
ElseIf ( $size -ge 1PB ) { $sizeOutput = "$("{0:N2}" -f ($size / 1PB)) PB" }
$sizeOutput
}}
Get-ChildItem -Path $Path | Where-Object {$_.PSIsContainer} | ForEach-Object {
$size = ( Get-ChildItem -Path $_.FullName -Recurse -Force | where {!$_.PSIsContainer} | Measure-Object -Sum Length).Sum
$obj = new-object -TypeName psobject -Property @{
Path = $_.Name
Time = $_.LastWriteTime
Size = $size
}
$obj
} | Sort-Object -Property Size -Descending | Select-Object Path, Time, $PrettySizeColumn
用法:
#Current directory (default value)
.\Get-FoldersWithSize.ps1
#Relative path
.\Get-FoldersWithSize.ps1 -Path ".\Downloads"
#Absolute path
.\Get-FoldersWithSize.ps1 -Path "C:\ProgramData"
