How can I get only one line for output of command in powershell?

Question

In Linux I use this for select specific line:

ip a | sed -n '3p' | xargs

But I don't know how can I make it in Powershell.

Answer 1

As Smorkster mentioned, powershell works in objects.

you can use dot notation as shown here to access a property of an object and then use indexing

(Get-NetIPAddress).ipaddress[3]

Answer 2

Powershell works (almost exclusively) in objects. That way you can use indexing to get a certain value/output. So you can do

( Get-NetIPAddress ).ToString()[3]
