复制项目并排除文件夹 [英] Copy-Item and exclude folders

问题描述

我需要将我的所有 c:\inetpub 目录复制到一个新位置，但排除以下文件夹及其子文件夹:

I need to copy all of my c:\inetpub directory to a new location but exclude the following folders and their subfolders:

c:\inetpub\custerr
c:\inetpub\history
c:\inetpub\logs
c:\inetpub\temp
c:\inetpub\wwwroot

到目前为止，我正在这样做:

So far I am doing this:

# Directory name is created with a format string
$dirName = "\\servername\folder1 _ {0}\inetpub" -f (get-date).ToString("yyyy-MM-dd-hh-mm-ss")
$dirName # Check the output

# Create dir if needed
if(-not (test-path $dirName)) {
    md $dirName | out-null
} else {
    write-host "$dirName already exists!"
}

#Copy Backup File to Dir
Copy-Item "\\servername\c$\inetpub\*" $dirName -recurse

推荐答案

这是您可以执行的操作的简单示例.构建要排除的父文件夹的数组.由于您是通过 UNC 路径访问它们，因此我们无法真正使用 c:\ 路径(我们可以解决这个问题，但我将要展示的内容应该足够了.)

This is a simple example of something you could do. Build an array of the parent folders that you want to exclude. Since you are accessing them via UNC paths we cannot really use the c:\ path (We can get around this but what I am about to show should be good enough.).

然后使用Get-ChildItem获取inetpub目录下的所有文件夹.使用 -notin 过滤掉排除项并将其余部分传递给 Copy-Item

Then use Get-ChildItem to get all the folders in the inetpub directory. Filter out the exclusions using -notin and pass the rest to Copy-Item

$excludes = "custerr","history","logs","temp","wwwroot"
Get-ChildItem "c:\temp\test" -Directory | 
    Where-Object{$_.Name -notin $excludes} | 
    Copy-Item -Destination $dirName -Recurse -Force

您至少需要 PowerShell 3.0 才能运行.

You need at least PowerShell 3.0 for this to work.
