How to repeat a command forever in Powershell?

I'm running a command that I want to rerun when it completes, without needing to navigate back to the terminal to enter the command again.

I know in Ubuntu, I can run a terminal with a command, and it'll loop forever if I have it set up right, something like gnome-terminal -x $MY_COMMAND.

Given that I can't mark Powershell to rerun the command instead of closing the window, how can I repeat a command indefinitely?

Turns out the answer is fairly straight forward, wrap the command in a loop forever. This'll allow you to Ctrl-C out of it, and it'll keep repeating even after your command completes or otherwise exits the first time.

while ($true) { my_command; } 

Or in my case as a one liner: while ($true) { python3 .\manage.py runserver_plus 8080; }

This will infinitely run a command repeatedly after execution completes:

while ($true) { Start-Process -FilePath python3 -ArgumentList .\manage.py, runserver_plus, 8080 -Wait -ErrorAction SilentlyContinue } 

Alternatively:

#requires -Version 3 while ($true) { try { $params = @{FilePath = 'python3' ArgumentList = '.\manage.py', 'runserver_plus', '8080' Wait = $true ErrorAction = 'Stop'} Start-Process @params } catch { <# Deal with errors #> continue } }
