Sometimes, newly-copied apps (though a bash script) end up retaining the "circle with strike-through" on top of their icon, even after running them. Restarting the system fixes this issue.
Is there any way to trigger a "refresh" of said icon, preferable exclusively, from the CLI? Since this is supposed to run on other systems than mine, I don't feel comfortable deleting the icon cache.
Asking in the context of OS X 10.8 and up.
[L.E.] I would also avoid relaunching Finder, if possible.
