I don't deny that it is much more powerful than cmd, but it feels a lot like "emacs rather than vi" in its design, and I much prefer the latter (which would be more (ba)sh-like.)
* usable tab-completion: scrolling through all available cmdlets is a poor substitute, and usually increases my keypresses instead of decreasing it.
* workable history editing: if I edit a previous command, I must remember to never use tab completion again, because pressing <tab> halfway in a command erases everything following the cursor
* consistent interface: In a powershell shell window, I can use left mouse button to select and copy, right mouse button to paste. In command shell window, I must use right mouse button to select "Mark" in context menu before even left-mouse selection works. In powershell ISE, left mouse button selects but does not copy, right mouse button still opens a context menu.
My first impression of it? It went like this:
Task: you need to connect to Hyper-V VM console via Remote Desktop.
Hiccup: for that, you need to know it's GUID. How to find it out? Just run this handy posh script... (https://blogs.msdn.microsoft.com/virtual_pc_guy/2014/11/25/u...)
Another hiccup: That script does not work, it needs some library that's not loaded by default. Try to find out how.
Another hiccup: It does not load, because it breaks some policy, that's off by default. Investigate, what to do.
How it ended: forget it, I have better things to do than solve problems with Powershell. Look into VM files and find out, that it's one of the GUIDs there.
Result: Won't touch posh again and anyone singing about its virtues is getting promptly ignored.
Maybe it's not fair to Powershell, but the first impression counts.
OTOH, you'll spend way less time scraping stuff for regexs and actually just asking posh for fields. It's really, really worth learning.
