problem with $_. RRS feed

  • Question

  • Hi,

    I have just started with powershell and programming. I am experimenting with Functions a bit. I would like to get al the files that have not been used or written to for a while.

    I have writen the script below:

    #Function Variables
    Function Get-Variabelen{
    $script:Path =  Read-Host "Welk path wil je zoeken"
    $script:Days = Read-Host "Hoeveel Dagen"

    #Function: DirectoryorFiles
    Function Get-Directoryorfiles{
    $dirorfilesvar = Read-Host "Wat wil je zien. Voor directory's [1] voor Files [2]"
    if ($dirorfilesvar -eq 1) {$script:dirorfile = "-Direcory"}
        Elseif ($dirorfilesvar -eq 2) {$script:dirorfile = "-File"}
        Else {write-host "Je hebt geen juist getal gekozen" exit}

    #Functions Get-Result
    function Get-Result{
    Get-ChildItem -Path $Path -Recurse $dirorfile | Where-Object {($_.LastWriteTime -lt (Get-Date).AddMonths(-$Days))} | select FullName, LastWriteTime


    The most part of the script works fine. But this part doesnt work:

    Get-ChildItem -Path $Path -Recurse $dirorfile | Where-Object {($_.LastWriteTime -lt (Get-Date).AddMonths(-$Days))} | select FullName, LastWriteTime

    When i execute the scipt by hand it works. But when i execute is in a scipt or function it writes this down.

    Get-ChildItem -Path $Path -Recurse $dirorfile | Where-Object {(.LastWriteTime -lt (Get-Date).AddMonths(-$Days))} | select FullName, LastWriteTime

    It always misses the $_. part after the where-object. I am doing something wrong. 

    Is there someone who knows what?

    Thanks in advance.

  • Please edit your post and format the code as code. That will avoid unwanted line breaks in your code.

    Your code is a little convoluted and overcomplicated for such a little task. But you could start with removing the parenthesis inside the curly braces of your not working Where-Object block.

    Live long and prosper!

  • What IDE are you using to write program?

    Can you provide the error message you are getting?

  • Variables defined inside a function do not exist after the function exits.
