Hi,

Take a look at Select-String:

http://ss64.com/ps/select-string.html

You can reference the below code to write your own .

$Avals=Get-Content C:\A.txt
$Bvals=Get-Content C:\B.txt
$Regex='(\d+)'
foreach ($Aval in $Avals)
{
	$MatchValue= $Aval | Select-String -Pattern $Regex | Select-Object  {$_.Matches}
	$Value=$MatchValue.'$_.Matches'.Value
	foreach($Bval in $Bvals)
	{
		if($Value -eq $Bval)
		{
			$Value | out-file C:\C.txt -Append
		}
		
	}
	
}

For matching one of multiple values, you can use regex alternation ('|') to do them all in one pass.

$regex = (get-content b.txt) -join '|'

Select-String a.txt -Pattern $regex |
select -ExpandProperty Line |
Set-Content c.txt

You can also use the -match operator instead of Select-String if you just need the text of the matched lines:

(Get-Content a.txt) -match $regex |
Set-Content c.txt

 

thank you. your answer it's work.
