I've just started reading various books on SharePoint development and have come across a wonderful tool called PowerShell. From the looks of it, it could replace the old DOS tool cmd.exe. There are a few blogs discussing PowerShell vs. cmd.exe, but I have found none really useful one discussing PowerShell vs. cmd.exe in the eyes of a SharePoint developer.
Simply put, is it possible to only use PowerShell as the only command line tool as a SharePoint developer, or do you still rely on cmd.exe?
