Doing things in PowerShell is often simple, but finding them out for the first time is sometimes not. This little tidbit took a good half hour of my day. I wanted to call another script from my first script. I didn’t mind if I needed to wait for execution to finish before moving on, and I had no requirements to pass variables or any information between scripts. This did the job for me:
If it can’t be done in PowerShell (yet!), there is the option of calling psexec or powershell.exe or cmd.exe directly using Invoke-Expression. MoW talks about calling a process and leveraging the WaitForExit method, which could be useful as well.
