Hi Gary,
The Terminal uses a Unix command shell and yes,that's exactly the syntax used. I copy and pasted the command into the terminal window as is and it worked in solving my Error 16 problem by fixing the permissions the CC Desktop installer altered.
I'm out of ideas at this point and I don't want to engage in guess work when it comes to your system. If no one has any ideas in the community forums,I'd give Adobe Tech support a call.
CS6 refers to the previous Creative Suite, CC is the new version released June 17th. It could be called "CS7", but since it's Cloud license only, they've branded it CC for Creative Cloud.
