Split string with PowerShell and do something with each token

Question

I want to split each line of a pipe on spaces, and then print each token on its own line.

I realise that I can get this result using:

(cat someFileIn         


        

Answer 1

-split outputs an array, and you can save it to a variable like this:

$a = -split 'Once  upon    a     time'
$a[0]

Once

Another cute thing, you can have arrays on both sides of an assignment statement:

$a,$b,$c = -split 'Once  upon    a'
$c

a
