... So I'm thinking of making a shell script that will: 1) compare two folders 2) move files from SOURCE to TARGET which don't exist on TARGET 3) compare files which exist on both. 3a) If identical, delete the copy from SOURCE. 3b) If not identical, move from SOURCE to TARGET But then I thought "I wonder if I'm reinventing the wheel?" Any ideas? Where should I be looking? >From your description: cp -R <source> <target> should do the trick. Read the man page. Craig
