Dear Team,

I have a script to obtain all browsers extensions (Safari, Edge, Chrome and Firefox) the script is running well and I would like to use it as EA. Can any body give a hand? Thanks

Here is the output 

[Warn] This script may not be able to access all user directories unless run as root.

Safari Extensions:

Chrome Extensions:

Firefox Addons:

It should be as simple as adding <result></result> to the if/then statement that echos output if _arg_multilineField and _arg_wysiwygField are not set. In my IDE I set line 415 to 

echo "<result>"

and line 443 to:

echo "</result>"

So the last 35 or so lines of the script look like this:

 

# If both _arg_multilineField and _arg_wysiwygField are not set, or if there is an error saving to the custom fields, print the results
if [[ -z $_arg_multilineField && -z $_arg_wysiwygField ]] || [[ $EXITCODE -ne 0 ]]; then
    echo "<result>"
    echo "$safari_title:"
    echo "$safari_extensions" | while IFS='|' read -r user name id; do
        if [[ -n "$name" ]]; then
            printf "User: %s, Name: %s, Id: %s\n" "$user" "$name" "$id"
        fi
    done
    echo ""
    echo "$chrome_title:"
    echo "$chrome_extensions" | while IFS='|' read -r user profileName name id version; do
        if [[ -n "$name" ]]; then
            printf "User: %s, Profile Name: %s, Name: %s, Id: %s, Version: %s\n" "$user" "$profileName" "$name" "$id" "$version"
        fi
    done
    echo ""
    echo "$firefox_title:"
    echo "$firefox_addons" | while IFS='|' read -r user profileName name id description; do
        if [[ -n "$name" ]]; then
            printf "User: %s, Profile Name: %s, Name: %s, Id: %s, Description: %s\n" "$user" "$profileName" "$name" "$id" "$description"
        fi
    done
    echo ""
    echo "$edge_title:"
    echo "$edge_extensions" | while IFS='|' read -r user profileName name id version; do
        if [[ -n "$name" ]]; then
            printf "User: %s, Profile Name: %s, Name: %s, Id: %s, Version: %s\n" "$user" "$profileName" "$name" "$id" "$version"
        fi
    done
    echo "</result>"
    # If no extensions are found, print a message
    if [[ -z "$safari_extensions" ]] && [[ -z "$chrome_extensions" ]] && [[ -z "$firefox_addons" ]] && [[ -z "$edge_extensions" ]]; then
        echo "<result>[Info] No Browser Extensions Found</result>"
    fi
fi

 

That seemed to work in my very limited testing, and produced an EA that looked like this on a machine that only has extensions in Edge:

Hi Everyone,

 

The script worked for me and reflected its output in the Details section under Logs. However, I did not understand how to export this data. Do you have any comments on this?

If you need to export the data you can use an Advanced Search. Select the checkbox on the Extension Attributes tab for the EA that you want to export. Then use the Report tab to export a CSV or schedule the sending of the report.

Thank you @stevewood

This scripts returns old Safari Extension details which removed already and not printing the current Safari Extension which is installed on the device.

Also capturing and returns multiple entry for same extensions with different versions
