Question

I have PowerShell 3 installed, and I need to run PowerShell 2 from Cygwin

$ PowerShell -Version 2

C:\Users\Michael> $host.Version

But as you see it is still running PowerShell 3.

Do you have any ideas what am I doing wrong?

If you curious why I need to run PowerShell from Cygwin, it is because of the git hooks I am writing.
To develop server-side hooks I write PowerShell script, and because of the problem described above, I cannot use my nice trick with breakpoints

UPD: I am using Cygwin 1.7.11 terminal on Windows 8

UPD: I can even run cmd in between to make sure that parameters are passed properly

Answer 1

Works as expected for me.

You might have to give more context to see why this is not working. Only reason I can think of is somehow the -Version 2.0 param is not being passed to powershell.
