Creating Smart Group to sort by Screen Sharing Version

You could make an extension attribute for the version number with a command like this:

defaults read /System/Library/CoreServices/Screen Sharing.app/Contents/Info.plist CFBundleShortVersionString

The command works when I run it in Terminal on a machine and returns the version number, but when I create an extension attribute using that command it always returns as blank.

Post your script.

Extension Attributes must echo back any result within <result></result> tags or you get a blank result.. In other words, like this-

echo "<result>$version</result>"

Jacob's command above was only an example of what to use, not a full Extension Attribute script.

#!/bin/sh
version= defaults read /System/Library/CoreServices/Screen Sharing.app/Contents/Info.plist CFBundleShortVersionString
echo "<result>$version</result>"

Close. Your script needs to store the variable as the output of the command. You can do so by putting in between a $ and two parentheses:

#!/bin/sh
version=$(defaults read /System/Library/CoreServices/Screen Sharing.app/Contents/Info.plist CFBundleShortVersionString)
echo "<result>$version</result>"

To be fair, you should probably mark Jacob's response as the answer, because he provided the defaults command to get the version string. All I did was clear up confusion on how to build an EA script.

Thank you, it wasn't working first but then I realized I had set the data type to "string" instead of "integer"

@mm2270 But yours provided better detail...

You both helped a lot, thanks!
