Automatic Naming Example - Using API

[FrozenWaltDisne]

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.

#!/bin/bash

MACADDRESS=$(networksetup -getmacaddress en0 | awk '{ print $3 }')
JSS=https://yourcompany.jamfcloud.com:443
API_USER=api
API_PASS=password


## Get JAMF XML
XML=$( curl -H "Accept:text/xml" -ksu $API_USER:$API_PASS $JSS/JSSResource/computers/macaddress/$MACADDRESS -X GET )

##Find ID
#String to search
STRI="<id>"
#Find Position in string
IDPOS=${XML%%$STRI*}
IDPOSNUM=${#IDPOS}
#Find length of search variable
STRLNGT=${#STRI}
#Start after Tag
IDFPOS=`echo "$STRLNGT + $IDPOSNUM" | bc`
#Terminate string Length
IDFPOST=`echo "$STRLNGT + $IDPOSNUM + 10" | bc`
#Grab String and cut excess
ID=`echo ${XML:$IDFPOS:$IDFPOST} | cut -d "<" -f 1`

##Find Department
#String to search
STRD="<department>"
#Find Position in string
DPTPOS=${XML%%$STRD*}
DPTPOSNUM=${#DPTPOS}
#Find length of search variable
STRLNGTD=${#STRD}
#Start after Tag
DPTFPOS=`echo "$STRLNGTD + $DPTPOSNUM" | bc`
#terminate string length
DPTFPOST=`echo "$STRLNGTD + $DPTPOSNUM + 10" | bc`
#Grab string and cut excess
DEPT=`echo ${XML:$DPTFPOS:$DPTFPOST} | cut -d "<" -f 1`

##Find Location
#String to search
STRL="<building>"
#Find Position in string
LOCPOS=${XML%%$STRL*}
LOCPOSNUM=${#LOCPOS}
#Find length of search variable
STRLNGTL=${#STRL}
#Start after Tag
LOCFPOS=`echo "$STRLNGTL + $LOCPOSNUM" | bc`
#terminate string length
LOCFPOST=`echo "$STRLNGTL + $LOCPOSNUM + 10" | bc`
#Grab string and cut excess
LOCATION=`echo ${XML:$LOCFPOS:$LOCFPOST} | cut -d "<" -f 1`


#Find if it's a laptop
IS_LAPTOP=`/usr/sbin/system_profiler SPHardwareDataType | grep "Model Identifier" | grep "Book"`
#find ID length
idlength=`echo ${#ID}`

#Add Location
if [ "$LOCATION" = "Home Office" ]; then
   PREFIX=HO
else
  echo "Unknown Location"
  exit 1
fi

#Determine Laptop or Not
if [ "$IS_LAPTOP" != "" ]; then
    PREFIX=$PREFIX"L"
else
    PREFIX=$PREFIX"D"

#Sort Department Naming

    PREFIX=$PREFIX"777"

    PREFIX=$PREFIX"444"
else
    PREFIX=$PREFIX"XXX"
fi

#format ID to 3 characters
if [ $idlength -gt 3 ]; then
    ID=echo ${ID: -3}
    Name=$PREFIX$ID
elif [ $idlength -lt 3 ]; then
    ID="0"$ID
    Name=$PREFIX$ID

    Name=$PREFIX$ID

#set name to match

#Report to Jamf

exit 0

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.
