Problem with naming computer

Hey all,
A number of years ago I inherited a Jamf platform that I am trying to improve and clean up. We have a policy of naming computers of your choice. Currently, it consists of three scripts, one of which is an AppleScript to bring up a dialog box where you can enter the desired name of the computer.

This solution has worked fairly well until about a year ago. Now you have to run the script twice for it to work, at least for Ventura and Sonoma.

The script looks like below and I was wondering if someone could help me, give me some tips to make it work better so that you don't have to run it twice?

Thanks in advance.

First script (how it's listed in Jamf policy)

#/bin/sh
#Skript som sätter en raett hostname osv. - Made by Marten B. BK.IT

#define variables
name=$(sudo /usr/sbin/scutil --get ComputerName)
sname=$(echo "$name" | tr -cd '[[:alnum:].-]')

        # set computernames
		sudo /usr/sbin/scutil --set HostName "$name"
		sudo /usr/sbin/scutil --set LocalHostName "$sname"
        sudo defaults write /Library/Preferences/SystemConfiguration/com.apple.smb.server NetBIOSName -string "$sname"

sudo dscacheutil -flushcache
sudo killall -HUP mDNSResponder

exit 0;


Second script

#!/bin/bash

sudo jamf recon
sudo jamf policy


Third script (AppleScript)

display dialog ”Set desired computer name: " default answer "like: SE304041-teacher" with icon note buttons {"Cancel", "Continue"} default button "Continue"
set ComputerName to text returned of result

display dialog ComputerName & " will be set as computer name.." with icon stop buttons {"OK"} default button "OK"

do shell script "/usr/sbin/scutil --set ComputerName " & ComputerName & space & "setlocalsubnetname " & ComputerName with administrator privileges

Have you thought about squishing this in to one script? Tossed something together for an idea, but I have not tested this and will need a bit of work to limit what the user can pick but the workflow should be good.

Thanks. I'll give it a try :)

Tried the script but get an error shown bellow. 🤔

@jonrosYou can do this all more simply using the Jamf binary.  That has the ability to change the computer name and does everything you have done making your script smaller.  The manual command if being done by yourself would be

 

 

sudo jamf setcomputername -name whatevernameyouwant

 

 

More info if you check the help for jamf

 

 

jamf help
jamf help setcomputername
