Power shell script

Not sure where to post this.
Can anyone tell me what this does.
C:\WINDOWS\System32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy UnRestricted function IJ($A) {$L = $Null;Get-ChildItem $A -Recurse -Depth 1 -ErrorAction 'SilentlyContinue' | ? {$_.extension -eq '.lnk'} | % {$Hu = [String](Get-Content $_.FullName);$
Someone found it on there computer, I could not answer the question for him.
powershell script - is it dangerous? - Windows 10

Thanks for any insight

It's only part of s script.

The code sets the Excecutionpolicy to Unrestricted (not good)

It then iterates through supposedly a folder passed to the function of all shortcuts in that folder

and copies the contents of each shortcut.

It's useless without parameters being passed to it.

To test run it like this:

Code:

$A = Join-Path $env:USERPROFILE -ChildPath 'desktop'
function IJ($A) 
{
$L = $Null
Get-ChildItem $A -Recurse -Depth 1 -ErrorAction 'SilentlyContinue' | 
? {$_.Extension -eq '.lnk'} | 
% {$Hu = [String](Get-Content $_.FullName)}

Write-Host $Hu
}

IJ($A)

The output would be:

Code:

Edit:

This is (I suppose) what the author intended:

Code:

function IJ($A) 
{
$L = $Null #<--Not sure what this is supposed to do

Get-ChildItem $A -Recurse -Depth 1 -ErrorAction 'SilentlyContinue' | 
? {$_.Extension -eq '.lnk'} |
% $_ {($Hu = [String](Get-Content $_.FullName) + [Environment]::NewLine)} | #Original script does not implement ForEach properly - fixed here

#Create a text file with the shortcuts' content
Out-File (Join-Path $A -ChildPath 'Test.txt')
}


#Add a folder with shortcuts
$A = Join-Path $env:USERPROFILE -ChildPath 'Desktop'


#Run it 
IJ($A)

It produces a text file in the same folder at the shortcuts (in this eg. Desktop) containing all the shortcuts' innards. I can't figure what the use of this may be.

I am NOT really up with PowerShell, but I would find this useful because I have a Toolbar with MANY Shortcuts, and it would be very useful to have the Target: and Start in: entries. Even the Icon Name and Icon Path for Custom Icons that are used.

I will have a look into this tomorrow for either a Batch Script or PowerShell Script solution.

Thank you very much for that.

You are welcome - please check unknown scripts and verify

... and just in case anyone is still confused - The Joker always saves the day ... just saying...

The target of a .lnk file is available as a column in Explorer:



So a Filter can be created to invoke Add-Member add the target as a propetrty of the FileInfo object retruned by Get-ChildItem:

Code:

Filter Add-LnkTarget
{
    If ( $_.Extension -notLike '.lnk' )
    {
        $_ | Add-Member -NotePropertyName LnkTarget -NotePropertyValue $Null
    }
    Else
    {
        $S = { (New-Object -Com shell.application).NameSpace($this.DirectoryName).ParseName($this.Name).ExtendedProperty('LinkTarget') }
        $_ | Add-Member -MemberType ScriptProperty -Name LnkTarget -Value $s -PassThru
    }
}

And can then be used in the pipeline:

Code:

gci | Add-LnkFileTarget | select name , LnkFileTarget | ft -AutoSize -Wrap

If you want all the properties of a .lnk file, make the property a custom object:

Code:

Filter Add-LnkInfo
{
    If ( $_.Extension -notLike '.lnk' )
    {
        $_ | Add-Member -NotePropertyName LnkInfo -NotePropertyValue $Null
    }
    Else
    {
        $wsh = New-Object -Com wscript.shell
        $s2  = { [PSCustomObject](($wsh.CreateShortcut($This.FullName)).PSObject.Properties | % -Begin {$hash=@{}} -Process {$hash.Add($_.Name,$_.Value)} -End {$hash}) }
        $_ | Add-Member -MemberType ScriptProperty -Name LnkInfo -Value $s2 -PassThru
    }
}

and could be used like this:

Code:

gci *.lnk | Add-lnkInfo | select name , {$_.LnkInfo.TargetPath} , {$_.LnkInfo.WorkingDirectory} | Format-List

--- or ---

Code:

gci *.lnk | Add-lnkInfo | select name -ExpandProperty LnkInfo | Out-GridView

If you add the Filter defintions to your PowerShell profile, they'll be available in every PS session.

Thanks for the reply, time, and information @KeithM.

I will have a look at this over the next day or two. I just need it to iterate through a folder on the Root of C:\ and extract the Target:, Start in:, Icon Name, and Icon Path.

I might start a new thread for this as I do NOT want to hijack the OPs Thread.
