Powershell script to get all Sharepoint user id and user login

Question

I am importing data into a SharePoint list. One of the columns is the user's login/name which links to their profile via their SharePoint user id.

FARMURL/userdisp.aspx?ID=56

In order to import correctly, I first need to pull out the id and login, so that I can match them to their appropriate rows, then import the data accordingly.

How can I get the logins and ids?

Answer 1

This could work, but only for a given SPWeb:

Get-SPUser -Web http://localhost | ForEach-Object { $_.Id }
