文件内容与文件夹名称不匹配时运行Powershell脚本

Question

I'm trying to run a Powershell script that only runs when the file contents of a .txt file match the name of a folder in a different folder. I don't know if I over complicated the script, but any help would be greatly appreciated.

$From = "c:\test folder\content"
$To = "c:\test folder\archive\new"
$Content = Get-Content -path "c:\Test Folder\Content\content.txt" | Out-String
$Archive = Get-ChildItem -path "c:\Test Folder\Archive\" -name | Out-String

If($Archive -notin $Content){ 
#gets child items and copies them to a new folder
Get-ChildItem $From -recurse | Copy-Item -destination $To
#gets content of file
$Text = Get-Content -path 'c:\test folder\archive\new\content.txt' 
#renames the item
Rename-item -Path 'c:\test folder\archive\new' -NewName $Text
}

Get-Content | Out-String Get-Content | Out-String is going to output an object of one string rather than an array of strings.

Example Text file with 3 lines:

(Get-Content -path Example.txt | Out-String).count
1
(Get-Content -path Example.txt).count
3

This means that when you do the array compare after using Out-String on the text file with -in / -contains is basically doing -eq .

As Matt suggests in the comments you could use wildcard or regex operators to look for the name inside the larger string.

$Content = Get-Content -path "c:\Test Folder\Content\content.txt" -Raw
$Archive = Get-ChildItem -path "c:\Test Folder\Archive\" -Name

If($Content -notmatch $Archive){ 

Alternatively, with the assumption that the Archive name is a row in the file. You could get rid of the Out-String and just use Get-Content to get the array of strings and use the array comparisons.

$Content = Get-Content -path "c:\Test Folder\Content\content.txt"
$Archive = Get-ChildItem -path "c:\Test Folder\Archive\" -Name

If($Archive -notin $Content ){
