I discovered something last week – I had not blogged about little things that I thought I had blogged about. What the heck does that mean? It means that I tried to reference my blog for something because I thought “I totally blogged about that”…and found out that was not the case.<\/p>\n
Starting now, I am fixing this situation. There was something that popped up today that called for a PowerShell script and the Get-ADGroupMember<\/a> cmdlet – get a list of users from a list of groups. Some users are in there more than once so this needs to be a distinct list, unless you are into manually cleaning up things like this, and then I will be sad for you. Because that is kinda sad.<\/p>\n I originally wrote a script with two arrays (one for the initial list and one for the de-duped list of users), but even though this is quick and dirty, that was a little too dirty. Enter the Group-Object<\/a> cmdlet – it takes this list of names and groups them. No black magic this time. Just a cmdlet, that comes baked into PowerShell giving me what I need.<\/p>\n What? You wanted the code too? Oh, OK.<\/p>\n There you have it – quick, dirty and to the point. Enjoy. \ud83d\ude42<\/p>\n UPDATE:\u00a0Mathias Jessen<\/a> tweeted a one liner for this….so no need for the one array! Woohoo!<\/p>\n I was trying to do this but was also just trying to get it done, and if in doubt, I slap things in arrays. Thanks Mathias!<\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" I discovered something last week – I had not blogged about little things that I thought I had blogged about.
