PowerShell-根据文件名和扩展名过滤子项

Question

I am attempting to filter a result based off the filename with a variable for the previous day and the file extension.

I have attempted to filter using different methods but the latest is the closes I have gotten.

$Date = Get-Date #-Format "yyyyMMdd"
$DateAdd = (Get-Date).AddDays(-1)
$DateStr = '{0:yyyyMMdd}' -f $DateAdd

$srcRoot = "U:\test\Processed"  
$exRoot = "U:\test\Extract" 


Get-ChildItem $srcRoot -Filter *.zip | Where-object -Property Name -Like *$DatStr  | Expand-Archive -DestinationPath $exRoot -Force

As of right now the code gets all the compressed files in the srcRoot directory. I am only trying to return the compressed file for the date variable.

Answer 1

Using recommendation from AdminOfThings 's comment above. I was able to filter the results as I was attempting.

Get-ChildItem $srcRoot -Filter "*$DateStr*.zip" 

This returns the correct file after testing.
