Load variables from text file

Question

The script below asks for the $tag1 variable and uses that, but instead of entering in 1 variable at a time, I want to load a text file with many variables. I know you can use Get-Content c:\scripts\test.txt | Foreach-Object but I am not sure how to use it in this situation.

Get-Content C:\Users\ajstepanik\Desktop\tags.txt | Foreach-Object { write-host $_

    #Windows XP 
    $reg  = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $tag1)
    $key  = $reg.OpenSubKey('SOFTWARE\Microsoft\Windows NT\CurrentVersion\WinLogon')
    $winxp = $key.GetValue('DefaultUserName') -replace '^.*?\\'

    #Windows 7
    $reg1  = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $tag1)
    $key1  = $reg1.OpenSubKey('SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI')
    $win7 = $key1.GetValue('LastLoggedOnUser') -replace '^.*?\\'

    set-alias psloggedon 'C:\Users\ajstepanik\Desktop\PSTools\PsLoggedon.exe'




    echo "Windows XP"
    echo "----------"
    echo $winxp

    "`n"

    echo "Windows 7"
    echo "----------"
    echo $win7

    "`n"

    $pstools = psloggedon \\$tag1
    echo $pstools

}

Answer 1

I'm not going to attempt to rewrite your script for you, but you need to do something like this:

$fileinput = Get-Content c:\tags.txt

foreach ($tag in $fileinput)
{
  Write-Host $tag
  # Or whatever it is you're trying to do here
}
