@Brad_G Thanks for that link. I'm seeing different results for Serial Number on each device but helpful to know the Volume and Activated entries.
@spraguga I found a hidden file that appears to have the same Serial Number that is displayed when going through a Creative Cloud app (Photoshop, Illustrator, etc) menu for Help>System Info. Seems to be the same hidden file whether it is a full suite install, a couple apps, elevated permissions, Named or Device license, or whatever. From the 30-40 computers I've polled from so far, they all have the same hidden file that is pulling the correct entry for but I'd be interested to know if the same is in your fleet. One note, is it seems to be working for CC 2015 & 2017, but not CS6.
I set this up as an Extension Attribute with Data Type: String and an Input Type: Script.
#!/bin/sh
serial=$(awk '{if(/Serial/) print $7}' < /Library/Application Support/Adobe/SLCache/TXVzZS0xLjAtTWFjLUdN.slc | cut -f2 -d">" | cut -f1 -d"<")
#If a number is returned, print the serial number. If not, the file is not found and will result with a "Not Installed" result
if [[ $serial =~ [0-9] ]]; then
echo "<result>"$serial"</result>"
else
echo "<result>Not installed</result>"
fi
Would love any feedback!
