Creating Extension Attributes Populated by a Custom Script


Manually-created extension attributes can be populated by hand in a text field or pop-up menu, or by running a custom script. This article contains guidelines for running a custom script to populate manually-created extension attributes.

If you choose to populate an extension attribute using a custom script, any text returned to stdout between the <result></result> tag is stored in Jamf Pro when the script runs.

For example, the following script can be used to populate a “Last User” extension attribute in Jamf Pro:

lastUser=`/usr/bin/last -1 -t console | awk '{print $1}'`

if [ $lastUser == "wtmp" ]; then
   echo "<result>No logins</result>"
   echo "<result>$lastUser</result>"


Access to Jamf Pro is required to create an extension attribute populated by a custom script.


To access additional examples of extension attribute scripts:

  1. Log in to Jamf Pro with a web browser.
  2. In the top-right corner of the page, click Settings.
  3. Click Computer Management. On a smartphone, this option is in the pop-up menu.
  4. In the "Computer Management-Management Framework" section, click Extension Attributes.
  5. Click New From Template.
  6. Click the extension attribute template for which you would like to view a script.

Is it possible to have a script that prompts the user to choose "personal" or "company owned" and have that choice populate an extension attribute field?

Patchoo has a bunch of code that will read, prompt and update computer data from the API.

This can read your ext attribute


Pretty rough and ready but it gets the job done.
