Reload the path in PowerShell
console, powershell, powershell-ise
Solution
Just to bring Rob's comment to light:
$env:Path = [System.Environment]::GetEnvironmentVariable("Path","Machine") + ";" + [System.Environment]::GetEnvironmentVariable("Path","User")
Problem
If I have an instance of PowerShell ISE running and I install something that modifies the PATH or I modify it in any way outside of PowerShell then I need to restart PowerShell for it to see the updated PATH variable. Is there a way to reload the path from within PowerShell without restarting it?
