Hi all,  
i am using below powershell script to replace node name in bunch of files.

> $path = "E:\Automation\_DevOps"  
> $pattern = "NODE \"  
> $new\_hostname = "$env:computername"
> 
> $files = (Get-ChildItem -Path $path -Recurse -Filter "\*.pcmd").fullname  
> foreach ($file in $files) {  
> echo $file  
> #$string = (Get-Content $file | Select-String -AllMatches $change\_from)[0]  
> $old\_hostname = (Get-Content $file | Select-String -Pattern $pattern | select -ExpandProperty line).Split("")[1]  
> Write-Host "old\_hostname $old\_hostname"  
> Write-Host "new\_hostname $new\_hostname"  
> (Get-Content $file).replace($old\_hostname,$new\_hostname) | Set-Content $file  
> }

if i run powershell script it works well but when i use same code in powershell\_script resource in chef it throws below error

# Error executing action `run` on resource 'powershell\_script[Update Configuration]'

When using EOH it’s like using double quotes, try adding \ in the path.

$path = “E:\Automatuon\_DevOps”
