Need help using Createfile to run a powershell script

1

Hello everyone,

I am using the following createfile that is exiting with code=1

delete __createfile
delete powershell.ps1

createfile until EOF
Get-NetAdapter * | Where-Object {{ $_.TransmitLinkSpeed -EQ “25000000000” }} | Set-NetAdapterAdvancedProperty -DisplayName “Jumbo Packet” -DisplayValue “9014”
EOF

move __createfile powershell.ps1

waithidden powershell.exe -ExecutionPolicy Bypass -File powershell.ps1

This is what is showing on the client log

If I run the PowerShell cmd directly on Windows it does what it needs to do.

What am I doing wrong?

Thanks!

Try saving off the generated Power shell file to test it.

I suspect it’s how you’re trying to escape the curly brackets though.

Your {{ is correct, that escapes the open-curly and translates to a literal { in the PowerShell script instead of beginning a Relevance clause. But I think your }} needs to change - because you’re not inside a relevance substitution, that is passed literally into the PowerShell script as }}

Any reason not to do this using BigFix’s native support for powershell?

So I had first tried it with the curly bracket on the front, but that didn’t work so I thought that maybe I needed that at the end as well…that didn’t work either. But lo and behold after you mentioned it, I tried it again with the double single curly on the front only and the action completed successfully this time. :face_with_diagonal_mouth:

corrected action script

delete __createfile
delete powershell.ps1

createfile until EOF
Get-NetAdapter * | Where-Object {{ $_.TransmitLinkSpeed -EQ “25000000000” } | Set-NetAdapterAdvancedProperty -DisplayName “Jumbo Packet” -DisplayValue “9014”
EOF

move __createfile powershell.ps1

waithidden powershell.exe -ExecutionPolicy Bypass -File powershell.ps1

At first that is what I was trying to accomplish, nice easy deployment with built-in PowerShell support but the action kept on failing.

At least it’s working now.

Thanks!
