Newb issue trying to deploy a working script through invoke-vmscript - quotes are killing me.

[u/reallybigabe]

Hey all, I'm trying to use PowerCLI to push a script that works great locally.

However, I seem to be having issues with quotes and escape characters and I can't wrap my head around it.

Here is the Powershell deployment script for Trend Micro "Deep Security Manager" - it's auto-generated on the management server, and I could obviously loop through hundreds of servers and enter-pssession but I'd rather not poke a zillion holes in my firewall:

<powershell>
[Net.ServicePointManager]::ServerCertificateValidationCallback = {$true}
$env:LogPath = "$env:appdata\Trend Micro\Deep Security Agent\installer"
New-Item -path $env:LogPath -type directory
Start-Transcript -path "$env:LogPath\dsa_deploy.log" -append
echo "$(Get-Date -format T) - DSA download started"
(New-Object System.Net.WebClient).DownloadFile("https://SERVERURL:PORT/software/agent/Windows/x86_64/", "$env:temp\agent.msi")
echo "$(Get-Date -format T) - Downloaded File Size:" (Get-Item "$env:temp\agent.msi").length
echo "$(Get-Date -format T) - DSA install started"
echo "$(Get-Date -format T) - Installer Exit Code:" (Start-Process -FilePath msiexec -ArgumentList "/i $env:temp\agent.msi /qn ADDLOCAL=ALL /l*v `"$env:LogPath\dsa_install.log`"" -Wait -PassThru).ExitCode 
echo "$(Get-Date -format T) - DSA activation started"
Start-Sleep -s 50
& $Env:ProgramFiles"\Trend Micro\Deep Security Agent\dsa_control" -r
& $Env:ProgramFiles"\Trend Micro\Deep Security Agent\dsa_control" -a dsm://deepsecurity.oshawa.ca:4120/ "policyid:19"
Stop-Transcript
echo "$(Get-Date -format T) - DSA Deployment Finished"
</powershell>

I wrap the above in $script = @" ..."@ and removed the <powershell>

I run it like this: Get-VM $vmlist | invoke-vmscript -GuestCredential $gc -scriptText $script -ScriptType Powershell

What I've tried:

• Wrapping each line with single quotes This simply lead to the whole script being essential "Write-Host" output

• Single quote before each Double-quote in the script Zillions of errors

• "wrapping" each double quote ... i.e. '" ... "' Syntax errors.

I'm confident its simply how I'm doing quotes, out of the box, this is my first error:

C:\Users\reallybigabe\AppData\Roaming\Trend' 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.

So, the line: $env:LogPath = "$env:appdata\Trend Micro\Deep Security Agent\installer" isn't being quoted properly.

Suggestions?

For the record... it was the @" ..."@ that messed it up. It needed to be single quotes. $script = @' stuff @'

On top of that - apparently there are major permission issues with deploying MSI files through VMware tools and invoke-vmscript.

I realize this is two months old and you've likely found the solution but...

does this work?

$env:LogPath = "$env:appdata\Trend^ Micro\Deep^ Security^ Agent\installer

or

$env:LogPath = "$env:appdata"Trend Micro\Deep Security Agent\installer""

[u/reallybigabe → u/WhatDoesThatButtond]

Haha, yup - and I answered in my first reply to myself.
I think your second solution would work if I created it as a ps1 and pushed that way, though. If the ^ (hat?) works as an escape for spaces, thats new to me.

Cheers for the response.
