Powershell single line file exists check

Hi Powershell experts,

please help me in the logic. Below is the current single line script.

foreach($line in Get-Content C:\filepath.txt){(Get-Content $line).replace('DB_URL', ${RDSInstance.Endpoint.Address}) ^| Set-Content $line}

Open in new window

Would like extend a bit by
  1. check if file exists, then apply replace logic,
  2. else get next line

Haven't tested this but it should work:

$FileCheck = "c:\filepath.txt"; if (!test-path $filecheck){Exit}else {try{foreach($line in Get-Content C:\filepath.txt){(Get-Content $line).replace('DB_URL', ${RDSInstance.Endpoint.Address}) ^| Set-Content $line}}catch {write-host "Something Went Wrong Processing line $($line)"}}
