Why so?
Because Power Shell is teh best thing invented in this century, IMO
Far from it that there are no tries before that, but nothing that succesifull. Guys developing it took the best out of it, unix shells and scripting languages around and combined it into PS.
I will compare it to unix shell, because I don't find cmd.exe to be shell worth mentioning (its quite emberessing)
So, if bash is 10, Power Shell is 100. I never thought I will say this for any MS product .....
After reading interview with architect / developer it was clear why is that so... both dont' come from windows society.
Its a lot there to grasp, but in short, you have object oriented console where you can pipe objects between CLI apps (cmdlets) without loosing any information (contrary to bash text parsing). The best thing is that every shell important thing is stanardised, like names of custom cmdlests or names of parameters of cmdlet to prevent so called "syntax explossion" coming from using dozens of lil CLI tools from different developers each inventing its own little syntax. You have access to entire dotNet framework etc...
For instance:
Get-Process | ? { $_.Threads.Count -gt 25 } | Tee-Object c:\1.txt
First cmdlet, return array of objects (each is dotNet type Process) which are then sent to ? (where-object) for filtering those that have more then 25 thread which are then sent to file via Tea cmdlet and to output.
OR
new -type file -name Foo.txt -value "Foo"
new -type Variable -name MyVar -value 4
new -type Function -name MyFunc -value { some code }
new -type Registry ....
Here, each command is implemented in different provider but they all conform to the same standard, so usage is the same, no matter if you want to make file or function or registry key.
Why cmd.exe CLI tools loose value ?
Becase its not in the PS spirit, although you will be able to use them in PS too the same way as in cmd.exe. The simple fact that they are not accepting objects as input and give objects as output makes them 2nd league comparing to pure PS cmdlets.
Its amazing tech. Everybody should know it. Crossplatfrom port is 40% finished.
