foreach with two or more equal strings, how?

Question

using test script on my printserver I'm getting some output:

I need to launch foreach or same process for this, but before that I need to delete one of dnj-500.1 strings. How can I do this via powershell?

So you just want to delete the duplicates? – Martin Brandl Mar 30 '16 at 08:50 — Martin Brandl, Mar 30 '16 at 08:50

Both approaches work. Be sure, to select the right column (Name):

(I used get-process for demonstration purpose)

(get-process).count
133

(get-process | select name -Unique).count
106

(get-process | select name | Get-Unique -AsString).count
106

Hmmm, and if I have more than one column? `Name, Smth1, Smth2` and I need to kill strings with duplicate names? – Utka Kanibal Mar 30 '16 at 10:51
add smth1, smth2 etc to the select Statement. `select Name, Smth1, Smth2` – Martin Mar 30 '16 at 11:56

Solved this by using Sort-Object | Get-Unique -AsString

| select -unique leaves only

Name                                                                                                                        
----                                                                                                                        
dnj-500.1

Kinda strange, but Get-Unique result is fine.

try `| select Name -unique`. This should just delete the duplicate names. – Martin Mar 30 '16 at 09:48
