this script icacle doesn't work on remote computers. please help

I had this question after viewing Powershell script- running set owner command on multiple servers at once.

Hello,
I have closed the question because the error was fixed and I can run the script now, but the icacle command still only works on the local computer and if I execute it through the command NOT powershell.

I get this error

OI : The term 'OI' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included,
verify that the path is correct and try again.

    + CategoryInfo          : ObjectNotFound: (OI:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException



Here is the script.
Please help:

    param([Parameter(Mandatory=$true,
    ValueFromPipeline=$true,
    ValueFromPipelineByPropertyName=$true)]
    [Alias('hostname')]
    [string[]$ComputerName,

)
Begin {

 if ($nameLog)
   {
       Write-Verbose "Finding name log file"
       $i = 0
    do {
    $logFile = "names-$i.txt"
    $i++
    } while (Test-Path $logFile)
    Write-verbose "Log file name will be stored $logfile"

    }

Set-Permissions -computername server01, server02

Often when calling externals applications, it is a matter of trying quoting different parts, or even escaping certain characters.  
This should work.
icacls E:\ /grant "TESTTARGET\user.svc:(OI)(CI)(F)"
#or
 icacls E:\ /grant TESTTARGET\user.svc:`(OI)`(CI)`(F)

Open in new window


Another useful technique if using PS 3.0+ is "--%" (the stop parsing operator).
icacls E:\ --% /grant TESTTARGET\user.svc:(OI)(CI)(F)

Hello,
thank you so much

With quotes the script is now working but still not updating the remote computer. It doesn't give me any error either.
icacls E:\ /grant "TESTTARGET\user.svc:(OI)(CI)(F)"

Is this the correct command?
Invoke-Command -ComputerName (Get-Content ".\servers.txt") | Set-Permissions

I ran this command with the script and it only updated the local computer
Set-Permissions -computername server01, server02.testtarget.local
oh. I made this work without using a function. How do I pass the function in the script block?

Invoke-Command -ComputerName server02.testtarget.local -Scriptblock {icacls E:\ /grant "TESTTARGET\Administrators:(OI)(CI)F"} -cred testtarget\service

This didn't work with the script I posted above
Invoke-Command -ComputerName server02.testtarget.local -Scriptblock {get-permissions} -cred testtarget\service
Just like variables have scope, functions don't exist outside of the session in which they were defined/created.  Say you open a PS console and create the function, then open another PS console and try to run the function in that window/session - it won't work because the function was only created in the first session.  The same thing applies to remote sessions.

So the only way to run a function in a remote session is to define the function in that remote session.  Just like in a local session, you first run the code that defines the function, then you run the function.  Using the Invoke-Command cmdlet, your scriptblock that you call to be run has to include all those elements.
ok. I understand what you are saying but how to make it work.

Ok, I revised the script but somehow it still doesnt process the remote computer. Posting the revised script here .

Please help. See the screenshot with the results.

oh my fault. It is working now!! You are brilliant. I had a group wrong here because I didn't post the real group name.

 icacls E:\ /grant "TESTTARGET\Administrators:(OI)(CI)F"
        icacls F:\ /grant "TESTTARGET\ADMS.Administrators:(OI)(CI)F"
thank you so much! Tested and it is working great now!
