+1Hi,
I am trying to create a naming script for computers in my organization based on the inventory preload /Asset Tag field. The goal is to have the computer name be set based on the serial number.
i.e.. If serial is 12345 then name be set to COMP-ID-01
Thanks,

+12Try using the Jamf setComputerName command.
While it doesn't explicitly give you the ability to pull from the asset tag field, it does let you Pull the data from a CSV file.
+8If you are still looking for the solution to this, I recently wrote a script to do this exact thing. The only requirement is that there needs to be an Extension Attribute in the Preload Inventory to define the desired computer name.
It's got some built-in redundancies when naming the computer, but that was by design to make sure all bases were covered.

Hi, cam you help me with this, how to change your script to work 'Asset tag' (just grab Asset tag from Jamf and change the name of the computer to this)? Thanks

Dawid,
Because "asset_tag" is in a different section of the API output, it was easier to create a new script that references the separate section. This version uses "asset_tag" specifically.
