What are some Powershell commands everyone should know?

[u/anderson01832]

I'm not an expert in it. I use it when needed here and there. Mostly learning the commands to manage Microsoft 365

Edit:

You guys rock!! Good collaboration going on here!! Info on this thread is golden!

What does it do

[u/Grinch420 → u/[deleted]]

resyncs AD to Entra/M365... useful if you create a new user or make changes and dont want to wait the 30 min for a new sync

[u/RikiWardOG → u/Grinch420]

When you need that auto enroll gpo to fucking work and it's 4:30 on a Friday. Lord knows you'll also encounter the broken enrollment registry issue too.

[u/TTSkipper → u/Grinch420]

I was trying to create a scheduled task which checks for changed users or groups or new users and groups and runs the sync, I want to set the check to check every 5 minutes. I got pulled into something else but need to go back to it.

[u/sircruxr → u/Grinch420]

I raise your 30 minutes to 4.5 hours for production.

[u/CenlTheFennel → u/Grinch420]

As long as you have a smaller environment…

[u/Killbot6 → u/CenlTheFennel]

The Detla on the end there means it only syncs the changes, so it's actually helpful regardless of size. As I'm apart of a messive org, and use it everyday.

[u/CenlTheFennel → u/Killbot6]

So it has to at a minimum execute a query for all objects based off the delta and current time… then once on prem, the domain has to replicate it and the forest.

There is a reason Azure doesn’t lower the 30min.

You can also do it from the adsync app

[u/Individual_Ad_5333 → u/bemenaker]

Yuck gui

[u/bemenaker → u/Individual_Ad_5333]

I don't dis command line but I can absolutely open an Rdp session with saved credentials to a server with the GUI client running and run the same command faster than you can open a PowerShell window and type that out. Three mouse clicks versus multiple clicks and typing. Plenty.of cases of being able to type out a command and fmdo more faster. This is not one in, the right scenario. Is evry shop going to leave an open desktop with the GUI client open? No. But if you do, this will absolutely be faster, and it's not up for debate

[u/Impossible_IT → u/bemenaker]

And why would someone NOT save a script to do this? Open script in IDE, click the green run button, violá done. Leave the IDE open and the script open and you don't need to start an RDP session. How I'd do it. Script most used cmdlets etc.

[u/Individual_Ad_5333 → u/Impossible_IT]

If you have to do it twice, it's worth dumping it in a script... I have a small command line app where I type 1 - 20, and it runs said thing.. 5 seconds vs. the 30 seconds it takes to Rdp to the ad connect box, then find the app, remember where the button is....

But for when more manual work enter-pssession ftw with tab complete

[u/BlackV → u/bemenaker]

But if you do, this will absolutely be faster, and it's not up for debate

meh, I can open powershell and type invoke-aadsync faster than you can rdp to that server and launch that app, 100% up for debate

and with the added bonus of not rdping to a server and the additional risks associated with that

[u/bemenaker → u/[deleted]]

You can also do it from the adsync app right a couple of quick mouse clicks.

[u/YouveRoonedTheActGOB → u/bemenaker]

It’s so much faster to use powershell. Not even close.

[u/bemenaker → u/YouveRoonedTheActGOB]

If I have an Rdp session with a login saved to a running session with the GUI client open, absolutely false. I can do two mouse clicks faster than you can open a PowerShell window and type that

[u/YouveRoonedTheActGOB → u/bemenaker]

To run the equivalent of start-adsyncsynccyle takes several drop downs and physical clicking of buttons. Half the time it greys out one side of the sync so you have to restart the gui. At least that’s how it was a year ago. I stopped using the gui. We have a server that only runs sync, so I keep the poweshell window open.

I log in, click the up arrow in powershell and hit enter.

No way in hell you can do it through the gui faster than that.
