Restart/Refresh Dock - killall Dock - cache

Question

I've made an app which changes the OSX Trash icon. However after it has replaced the icon .png files in .../CoreServices/Dock.app/Resources it will not show the new icon before the Trash has changed state (fx. empty -> full or full -> empty). I've tried making the change appear by using killall Dock, killall Finder but not working.. I've also read about deleting a dock cache file in Library/Caches/com.apple.dock... But i can't seem to find this file?

Can you help me?

Answer 1

I actually ended up using the bash command find . -name com.apple.dock.iconcache. Then I deleted all of the matches. It works perfectly!
