Does anyone have a really good tutorial or getting started guide for Microsoft's PowerShell? I'm a long time Linux/Unix user, and very familiar with scripting languages, command-line usage with bash, ksh and zsh. I'm an intermediate Ruby programmer, and have used all these tools for command-line file management and automation tasks.
I would love a "PowerShell for Bash Experts" guide if such a thing exists, or is on that level of detail.
