Disclaimer: I'm inexperienced with bash and powershell.

I just converted a bash script to a powershell script. Some things are a lot easier (like writing errors or info messages in different colors). But I had a lot of problems getting the exit codes from maven calls to determine the exit result. Checking for 0 in shell works fine all the time, in powershell checking $LASTERRORCODE works sometimes but not always. I'm using try catch now but it's a bit of a hassle (which is ironic, comic from a java developer).
