How to launch PowerShell script from the OS command line?

I have a PowerShell script for building my project files, and I'd like to have capability to run it from my file manager's command line (and, possibly, make a shortcut to this script so I can start build from my desktop)
Any way to do this?

If you're on PowerShell 2.0 use:

PowerShell.exe -File c:\users\john\myscript.ps1

If you're on 1.0 use:

PowerShell -Command "& {c:\users\john\myscript.ps1}"

Depending on what you do/load in your profile script you may also want to specify `-NoProfile`. Of course, if your script requires something that is loaded in your profile then don't use this parameter. Otherwise, it can speed up execution of your script a bit.
