How can I trim/split the following

aa-computername-cc
aa-computer-name-cc

I basically want to trim the aa- and the -cc, but leave the computer name regardless if it has a "-" or not.

Easy: takes two steps:
1. Split the name on "-"
2. Rejoin the name, skipping the first (id=0) and the last (id=count -1)

$Original = $ComputerName -Split "-"
$Final = (1…($Original.count - 2) | foreach {$Original[$]}) -join "-"

Worked like a charm. Can you briefly explain this line
$Final = (1…($Original.count - 2) | foreach {$Original[$]}) -join "-"

Thanks
