Bash Help required for Extension Attribute

Question

Hi,

I am trying to find all installed Apps from the Mac App Store which have not been purchased through the VPP/Self Service.

This is what I got with the help of an older Script from Craig Lindsey

#!/bin/bash
    
# JAMF Extension Attribute that finds any MAS apps
# that were NOT purchased through VPP
# Based on Script from: Craig Lindsey for Starz 2017-2-10


checkMD=$(mdfind -onlyin /Applications/ 'kMDItemAppStoreReceiptIsVPPLicensed == "0"')
#echo "### checkMD - $checkMD"

if [ "$checkMD" = "" ]
then
	echo "<result>Not Found</result>"
	exit 0
fi

result=""

mdfind -onlyin /Applications/ 'kMDItemAppStoreReceiptIsVPPLicensed == "0"' | while read VPPApp 
do
	AppName=$( echo "$VPPApp" | awk -F'/' '{print $NF}' | sed -e 's/^"//' -e 's/"$//')
	result+="$AppName"
	echo "### Result - $result"
	
done

echo -e "### Result-TEST - $result"

#echo -e "<result>$result</result>"

exit 0

And this is the Result I get

### Result - Push Diagnostics.app
### Result - Push Diagnostics.appiMazing Profile Editor.app
### Result-TEST -

How can I transfer the $result from the loop to the end of the script?
Thanks in advance!

Hi @daniel_behan

thanks for the help, my "problem" is solved :-)
This is the EA which I use now:

#!/bin/bash
# Extensions Atrribute: Find all appstore apps in /Applications
# lists all apps not bought through VPP (Self Service)
# Based on Scripts from Heiko Horn 2020-04-16 and Craig Lindsey for Starz 2017-2-10

checkMD=$(mdfind -onlyin /Applications/ 'kMDItemAppStoreReceiptIsVPPLicensed == "0"')
#echo "### checkMD - $checkMD"

if [ "$checkMD" = "" ]
then
	echo "<result>Not Found</result>"
	exit 0
fi

# initialise a array list
arrAppStoreApps=()
# search the metadata for apps that were installed from the app store
arrAppStoreApps=$(mdfind -onlyin /Applications/ 'kMDItemAppStoreReceiptIsVPPLicensed == "0"')
# sort the array list
sorted=$(printf '%s\\n' "${arrAppStoreApps[@]} "|sort)

echo "<result>${sorted}</result>"

And this is the output I was looking for:

<result>/Applications/Push Diagnostics.app
/Applications/iMazing Profile Editor.app </result>

Here's the one I use to list App Store Apps, but I'm not parsing out which ones were assigned by VPP.#!/bin/bash# Extensions Atrribute: Find all appstore apps on this mac# lists all apps from the apps store# written by Heiko Horn 2020-04-16# initialise a array listarrAppStoreApps=()# search the metadata for apps that were installed from the app storearrAppStoreApps=$(mdfind "kMDItemAppStoreHasReceipt=1")# sort the array listsorted=$(printf '%s\n' "${arrAppStoreApps[@]}"|sort)echo "${sorted}"
