Some computer FAQ mostly Linux/Mac
Move a file from one user's Desktop to another on a Mac?
You need to run this script as SUDO, the first line COPIES the file and the second one MOVES the file.
I find this the fastest way to do the copy or move.
sudo cp /Users/user1/Desktop/yesterday.pdf /Users/User2/Desktop
sudo mv /Users/user1/Desktop/yesterday.pdf /Users/User2/Desktop
