Nice idea! Looks like the link is broken though:

Keep these coming! You're doing good work here.
Link should be:
https://github.com/ScottEKendall/JAMF-Pro-Scripts/blob/main/ClearBrowserCache/ClearBrowserCache.sh
yea...I am busy moving everything into files with appropriate READMEs and pictures..for some reason, I cannot change my original post to change the links I posted..
This is probably the best link to use: https://github.com/ScottEKendall/JAMF-Pro-Scripts
@ScottEKendall Hey Scott, I'm in the process of trying this script out. I'm not very good at scripting. I changed the portion that uses the .png file, but when I run the script via self service i get the error message. Am I missing something. What I changed was below. I just changed the top one to /Users/Shared and the bottom one to /Desktop/our.png. Thanks in advance.

yep...this line
/Users/Shared//logs/
shows that your LOG_DIR variable (line #38) is not correct...Also check line #35...that is the "root" of the support directory
