Powershell 编辑Get-DirStats.ps1以获取深度（子目录）参数
由于我是powershell的新手，我需要帮助编辑流行的Get-DirStats.ps1，它采用了一个新的（深度）参数，该参数将定义它将读取和输出统计数据的子目录数量 目前的代码将输出所有子目录，我需要限制的深度 这应该在powershell 2.0中，因为我有一些windows 7机器 ps1可在此处下载： 我从这条线索中学到： 这应该是一个普遍的解决办法： $Depth=2 $Levels=“*”*$Depth 但是将其添加到Get-DirStats.ps1会产生错误Powershell 编辑Get-DirStats.ps1以获取深度（子目录）参数,powershell,powershell-2.0,Powershell,Powershell 2.0,由于我是powershell的新手，我需要帮助编辑流行的Get-DirStats.ps1，它采用了一个新的（深度）参数，该参数将定义它将读取和输出统计数据的子目录数量 目前的代码将输出所有子目录，我需要限制的深度 这应该在powershell 2.0中，因为我有一些windows 7机器 ps1可在此处下载： 我从这条线索中学到： 这应该是一个普遍的解决办法： $Depth=2 $Levels=“*”*$Depth 但是将其添加到Get-DirStats.ps1会产生错误 # Written b

.SYNOPSIS
Outputs file system directory statistics.
.DESCRIPTION
Outputs file system directory statistics (number of files and the sum of all file sizes) for one or more directories.
.PARAMETER Path
Specifies a path to one or more file system directories. Wildcards are not permitted. The default path is the current directory (.).
.PARAMETER LiteralPath
Specifies a path to one or more file system directories. Unlike Path, the value of LiteralPath is used exactly as it is typed.
.PARAMETER Only
Outputs statistics for a directory but not any of its subdirectories.
.PARAMETER Every
Outputs statistics for every directory in the specified path instead of only the first level of directories.
.PARAMETER FormatNumbers
Formats numbers in the output object to include thousands separators.
.PARAMETER Total
Outputs a summary object after all other output that sums all statistics.
