An extremely powerful feature (that isn't all that well known) is the ability to assign values to multiple variables in one line. Take the following example:
PS> $one,$two,$three = "first","second","third"
PS> $one;$two;$three
first
second
third
This technique can be used in custom functions to parse the $args value
PS> function show-greeting {$greeting,$name = $args; "Hello $name, $greeting"}
PS> show-greeting "Nice to meet you" "Andy"
Hello Andy, Nice to meet youOne last thing to note is what happens if you have more values than variables. Does it blow up. An error. Not really. Check this out
PS C:\Users\andys> $one,$two = "first","second","third",4
PS C:\Users\andys> $one
first
PS C:\Users\andys> $two
second
third
4
PS C:\Users\andys> $one.count
PS C:\Users\andys> $two.count
3
PS C:\Users\andys>
The last variable gets the remaining values assigned to it.
