OS-X has six major flavors of the Bourne and Csh families of Unix shells already, any of which are at least as capable as Powershell
What I meant by that was that I can use those shells to do my work. Can't use Powershell.
When Powershell runs on the computers I use and administer, I'll reconsider its usefulness.
Until then, it's like a handsome, sexy male model in an advertisement. He may be attractive and exciting to half the population. But he doesn't do a thing for the rest of us. :)
