Change computer name via scutil and then change it in the JSS

Recon should update the JSS record. Wait up to 24hrs, or kick off a recon in your script.

If all you did was change the computer name then all it needs to do is check-in and the JSS should update to the new name.

Ok thanks guys. So at the end of my script I'll impose a check-in. Just to confirm, all that would be needed is "jamf policy" or a "jamf recon"?

I just did a quick test which showed 'jamf recon' is required at the end for the JSS to see the new name, yielding a different result than @strider.knh suggests. Of course, you should do your own tests to confirm.

@danshaw, if you're running this as a policy, you don't need to include the "jamf recon" trigger to force inventory to update. There's a maintenance category under any policy where you can select "Update Inventory", which will run recon after all other tasks have finished.

Awesome, thanks @NoahRJ . And thanks for the rest of you who also chimed in. I appreciate the help! I'll give it a try now.

I use a version of a cocoadialog enabled script in Self Service to enable local support staff to properly change a computer name and re-bind to AD with the new name. Check it out:

The ADBind policy has an "Update Inventory" on it, so I didn't include it in the script.
