This is the script we use. Pretty sure I got it off of here in the past, just make sure you fill in the apiUser, apiPass, and jssURL fields.

If I find exactly where I got it I'll give credit :D

We have this run on any computer that has the wrong name (IT Support account) and also automatically on newly imaged computers before they are assigned to users.

#!/bin/sh



## Change these 3 variables to match your setup. API account must have API write privs

apiUser=" ***** "

apiPass=" ***** "

jssURL=" ***** "



## get this Mac's MAC address

MAC=$( networksetup -getmacaddress en0 | awk '{print $3}' | sed 's/:/./g' )



## Create the xml for upload via API

echo "<?xml version="1.0" encoding="UTF-8" standalone="no"?>

<computer>

    <location>

        <username/>

        <real_name/>

        <email_address/>

        <position/>

        <phone/>

        <department/>

        <building/>

        <room/>

    </location>

</computer>" > "/tmp/blank_location.xml"



## Now upload the xml file

curl -s -k -u "${apiUser}:${apiPass}" "${jssURL}/JSSResource/computers/macaddress/$MAC" -T /tmp/blank_location.xml -X PUT

That script looked very familiar. It took a couple of searches to locate it, but looks like it came from this thread: https://jamfnation.jamfsoftware.com/discussion.html?id=10449

Just a quick note: There's a slightly modified version on the same thread posted by the OP that uses the Mac's serial number instead of a MAC address. I've made it habit myself to start using the Serial number lately with many of my API scripts.

Thanks to both of you. I do like the idea of using the serial number as we've gotten away from using MAC addresses wherever possible.
