Automatic Naming Example - Using API

This is a script that gives a specific prefix for Location, adds Dept, then adds an identifier. It's fairly specific but the bash script for scraping the API response is good to use on anything you want to retrieve from JAMF. I currently have the identifier return a 3 digits to align to our naming conventions, but feel free to change it.

I apologize for my bash scripting format... not my primary language.

I set this to run on enrollment, but it can actually continually be run and sets the same name.

DEP Setup: After you associate computer to JAMF, I made several enrollment profiles and just filled in the department and location areas. This allows you to have the purchaser set everything before it even arrives. However, this is the only real manual setup you need to do and could be part of the ordering process. The Policy itself it set to run after enrollment.

Hope that helps people with similar formats.

Edit: If your having issues with the API returns, I have it set to only move to 10 characters past where it sees the tag. You can adjust that by changing the 10 to whatever number you want. Technically I could put 100, but I wanted to run as efficient as possible.
